You can check the ESN history directly though the service provider or via an online database.

    How to Text From My Laptop to a Cell Phone

    Text messaging isn't relegated to just cell phones; they can also be sent from a laptop if you don't have a text messaging service, if you've used up your monthly text message allowance or if you find yourself in a location with a Wi-Fi signal but no cell signal. You have several texting options by accessing a website, sending an email or using Google Voice. Except for the latter, you'll need to know which wireless carrier your text message recipient uses.

    How to Port a Landline to a Cell

    When you first set up cell phone service, your mobile carrier may automatically assign you a new phone number by default. However, if you're making the change from a land line to a mobile phone, you don't have to lose your old phone number in the switch.

Mounting the right booster in your vehicle keeps the phone safe and stable on the road, while providing you with the communications, navigation and entertainment features to which you've become accustomed.

    Cheap Way to Boost a Cell Phone Signal

    Your phone may include a camera, GPS, gyroscope and 120 apps, but none of that helps you get reception when you are a little too far from the nearest cell tower. Your wireless provider is more than willing to help you -- if you're willing to shell out for a repeater or femtocell. If you're not flush with cash, or if you're in a pinch, you have cheaper options at your disposal.

    How To Download a GPS System Onto a Cell Phone

    The GPS chipsets built into modern cellular phones were initially intended as a way to locate subscribers who reported emergencies. However, they've made your phone capable of acting as a full-blown GPS navigation device when an appropriate app is installed.

You must purchase a separate rate plan called Laptop Connect or DataConnect if you plan on using your cell phone for tethering.

    How To Buy Home Video Equipment

    Home video equipment largely falls into three categories: HD video camcorders; DVD players and Internet media boxes; and flat screen televisions. In the field of DVD players and set-top boxes, the hardware has largely become commodity products – the components are identical and only the branding label makes any difference. Camcorders are nearly at that stage now, but there's a lot more differentiation in product types in that field. Most camcorders on the market are well made, reasonably priced and feature rich. Your primary choices boil down to a combination of the features you want and your available budget.

    How To Hook Up GPS

    Portable and cell phone-enabled GPS units can make travelling by car, bike or another type vehicle a safer and more pleasurable experience.

    What Is TTY Mode on Cell Phones?

    Cell phones have so many features, it can be tricky to figure out what they all do. One of the more mysterious options is the TTY mode. The TTY abbreviation stands for teletypewriter, a device that allows deaf or hearing-impaired individuals to communicate via the telephone by typing text messages. Cell phones with a TTY mode are compatible with this technology and perform the same service after they're connected to a TTY device.

    How to Buy an HTC Smartphone

    Before HTC became the first company to release an Android-powered phone, the T-Mobile G1, few Americans had heard of the Taiwanese manufacturer even though they have been making phones and other portable devices for other well-known companies since 1997. Since the release of the G1, HTC has come into its own as a major player in the cell phone and smartphone space and produces some highly sought-after models. HTC produces a variety of smartphones for other companies as well as those the company brands under its own name. If you are thinking about purchasing an HTC smartphone, you should consider several important factors before deciding on a particular model.

    How to Track Stolen Phones

    Losing an old-fashioned cellular phone was inconvenient, but nothing a new phone couldn't cure. With modern Internet-connected smartphones, losing a phone is a much bigger issue. Your smartphone probably contains enough personally identifiable information -- sometimes including credit card numbers and bank account passwords -- to cause serious problems. If your phone is lost or stolen, several apps and services can help you locate it before it can be resold or mined for data. Most will also lock or erase the phone.

    How to Operate the Car Remote Via Cell Phone

    Modern smartphones can be used for a wide range of noncommunications purposes, from playing games to acting as a remote control for your TV. They're also becoming a larger factor in automotive design.

    What Are the Differences Between OEM & Non-OEM Cell Phone Batteries?

    Handheld portable devices such as tablets and smartphones have become remarkably powerful since the turn of the century, and the most powerful can replace standalone computers for some uses. Unfortunately their powerful processors and large, crisp screens play havoc with battery life, and you might need to replace the battery before you replace your phone. Whether you're upgrading from choice or replacing a failing battery, you have the choice of a factory-original or third-party battery.

    How to Get Better Signal With Verizon Wireless

    Verizon Wireless sells cellular phone services and wireless data plans for both phones and as an alternative to conventional broadband services for the home. These data plans are part of Verizon's 4G LTE network. Wireless connections have any number of reasons for bad reception, mostly dealing with signal strength and the relative distance to a cellular tower.

    Difference Between Digital & Tri-Band Cell Phones

    Cellular phones use channels defined by frequency hopping within a slice of the broadcast spectrum. The four commonly used bands of the radio spectrum used by cellular phones are 850 MHz, 900 MHz, 1800 MHz and 1900 MHz. Of these, the 850 and 1900 MHz bands are most commonly used in the U.S. and Canada, while the 900 and 1800 MHz bands are more commonly used in Europe and Eastern Asia. A tri-band phone is one that has multiple antennas and can connect to any of these frequency ranges. Technically all tri-band phones are digital phones, but not all digital phones are tri-band; many sold in the U.S. and Canada only use the two frequencies that their carrier supports.

    How to Erase All Contacts on a Samsung

    The versatility of modern cell phones and tablets is one of their greatest attractions. Putting all your contacts, your calendar, e-mail and favorite websites onto a single, easy-to-use device is irresistibly convenient. Unfortunately, it also places your whole life at the fingertips of anyone else who uses that phone or tablet. If you plan to resell or give away a device from one of the major manufacturers, such as Samsung, it's prudent to spend a few minutes erasing your contacts and other personally identifiable data. Android and Windows devices all work much the same way, but feature phones are more variable.

    What Is the Difference Between 3G and 4G?

    When shopping for a new cell phone, one of the most important decisions you have to make is whether to select a 3G or newer 4G model. In most cases, 4G phones offer greater data speeds than their 3G counterparts, but this can vary based on a number of different factors. Understanding the different 3G and 4G technologies, as well as doing some research on coverage in your area, can help you decide if opting for 4G is worth the extra expense for you.

    How to Geocache Using a Phone

    With a smartphone in hand, geocaching can be a fun activity for the whole family to get outside and discover hidden treasures. Geocaching apps use the phone's Global Positioning System (GPS), which combines satellite GPS systems, cell phone towers and even Wi-Fi hotspots to pinpoint your location and compare it to the location of a nearby cache. Caches are usually filled with small toys or other trinkets left by those who have already found it. Don't forget to bring a trinket of your own to leave behind when you find the cache.

    How To Purchase a SIM Card

    A Subscriber Identity Module card contains a microchip that phones compatible with Global System for Mobile Communications use to identify users on a cellular network. SIM cards encode service plan and account information, encrypt transmissions, and can store text messages and basic contact information, such as names and telephone numbers. Most SIM cards purchased from United States cellular carriers are limited to a specific network and will not work on competing networks, especially for locked phones. However, network-independent, third-party SIM cards are available. These can be useful options for those who cannot commit to long-term contracts and for travelers looking for cost-conscious alternatives to expensive, overseas roaming charges.

    Does the Phone Make a Difference in Reception?

    Different cell phone models get different reviews on their overall quality and reception. Many factors contribute to cellular phone reception, including make and model of the cell phone. Each phone is a small, low-power transmitter, and each phone also has one or more antennas that pick up the signals from nearby cell towers.

    How To Purchase a Verizon Contract Phone

    Modern cell phones can cost a bundle. In fact, a smartphone can easily run over $500 if purchased without a contract. While that would give you the freedom to purchase service and disconnect it at will, it may be hard to swing that kind of cash up front. To avoid the major price tag of a new phone, purchase one with a contract from a cell service provider such as Verizon. This will lock you into a service plan for a period of years, but Verizon will subsidize the cost of the device - saving you money. Pick up the phone in a store to get it up and running immediately.

    Pros & Cons of Personal Tracking Devices in Cellular Phones

    Since 2001, cell phone carriers have been making it easier to track your cell phone, whether your phone uses GPS or not. Part of the reason is the FCC regulation that make it possible for 911 emergency services to locate emergency calls. However, police also use this information in non-emergency situations to identify where people have been and where they are in real time. When it comes to cell phone tracking, consumer benefits, as well as personal and public safety, intersect with privacy issues and the ability of criminals to use this information to endanger people and property.

    How to View the Icon Glossary on a Verizon LG Phone

    Spending a few moments browsing the Icon Glossary on your Verizon LG cell phone will help you to recognize some of the phone's key functions and features. The glossary is also a useful tool if you accidentally hit the wrong button on the phone's keypad and display an icon that you don't recognize. The Icon Glossary is available on most older LG cell phones, including the Glance, Versa and handsets in the VX series. Use the Verizon LG cell phone's keypad to navigate and view the gallery of icons and their descriptions in the Icon Glossary.

    Types of Antennas in Basic Communication Systems

    Whether you see it or not, every wireless device uses an antenna to send and receive radio frequencies. The size and shape of an antenna depends on the size of the signal's wavelength. High radio frequencies, like those used in cell phones, have short wavelengths, so the antennas can be very small. Low-frequency radio signals have long wavelengths, so longer antennas are needed. Antennas can be made from almost any metal or alloy. The part that receives or sends a signal is called an element. Other parts you may see protruding from an antenna are called reflectors or directors, which help capture the signal on the element.

    Texting With Apple iPhones

    Wireless phones were capable of sending text messages long before the iPhone came along, thanks to the Simple Messaging Service protocol. However, the iPhone's ease of use, with a full on-screen keyboard, visual display of an entire conversation and one-click access to send photos via MMS, was a quantum leap over the "triple tap," single-message SMS display of old-fashioned phones. Apple upped the ante with the iMessage service, which enables unlimited texting between Apple devices without messaging charges.

    Importing a Contact List CSV to the iPad

    Most contact-management software has the ability to export your contact list into a comma-separated value file, but no software native to the iPad can import it. Apple's iCloud system of contact management can import your contacts from most email programs, but that isn't quite the same as being able to export a subset of your contacts and just import them to the device. Getting the file imported requires the use of a third-party application.

    How to Improve In-House Reception of AT&T Wireless

    If you find yourself with a mobile-phone dead zone in part or all of your house, know that AT&T has developed a portable mini-receiver called a MicroCell that improves your in-house AT&T reception. The MicroCell uses your broadband Internet connection to increase cellular reception in your house. You can register up to 15 phone numbers to your MicroCell and connect up to four AT&T cell phones at the same time. The MicroCell only works with AT&T phones, so if you also use another carrier, contact that provider to find out if a similar option is available.

    About Cell-Phone Boosters for the Home

    Cell-phone boosters solve the problem of spotty coverage in your home. Better boosters often create a strong-enough signal for users to drop Wi-Fi, choosing to use their data service's 3G or 4G connection instead. Cell phone owners that routinely lose calls in certain areas of their homes most directly benefit from these devices, making cellular calls nearly as reliable as land-based phone connections.

    Does AppleCare Cover Lost iPhones?

    Thefts of cell phones -- especially the iPhone -- are on the rise. Apple offers an extended warranty called AppleCare+, which offers support for damaged or malfunctioning devices, but does not provide for the replacement of lost or stolen phones. You have up to 90 days after the date of the iPhone purchase to decide whether to purchase AppleCare+, which extends the traditional one-year warranty term to two years from the date of the original device purchase. Since it does not cover lost or stolen phones, your best bet may lie with considering private, third-party iPhone insurers.

    How to Use Android Cell Phone as a Modem to Get Internet on Your Computer

    Tethering your Android smartphone with your computer enables the device to share its cellular data connection, so your computer can access the Internet even when a wireless connection is unavailable. Android 4.x offers three ways to create this connection. Connecting your computer to your Android phone using a USB cable directly shares the Internet. Bluetooth-enabled computers can also pair with the phone to share data. The Android device also offers a portable hotspot feature that creates a Wi-Fi hotspot to which up to eight computers can connect.

    Tips to Increase Cell Phone Battery Life

    Your cell phone may state it has a specific battery life, but that's with minimal use. Apps, hardware settings and even the brightness of your screen all drain cell phone batteries faster than you may expect. With a few changes to your phone, you can increase battery life so your phone doesn't die when you need it most.

    How to Set up a Motorola Android With Wireless LAN

    Most Android smartphones from Motorola are configured with some kind of data plan through a cellular provider. However, this data plan might be extremely limited and incur additional fees should you go over your allotted bandwidth. To conserve bandwidth, your Wi-Fi enabled Motorola phone connects to mobile hotspots, so you use traditional LAN settings when browsing the Internet instead of your data plan. This setup potentially saves you considerable data bandwidth when downloading or sending large videos, photos and e-books.

    Changing the Background on a Samsung Android Phone

    Changing the Android wallpaper on your Samsung smartphone customizes the device with personal pictures or preset wallpapers included in the phone. Preset wallpapers include still and animated photos that offer quick activation on your phone. Personal pictures, including those you might have downloaded, are almost as easy to apply, but the phone additionally enables you to crop images. Selecting just a portion of the image enlarges the selection across the relatively small phone screen.

    Adding a PNG Signature to the Apple iPad

    You can change the email signature on your iPad in the settings menu, but you're limited to text only. If you want to use a PNG or other image format as a signature, you will have to add it manually for each email you send. While this might sound like a hassle, it's actually quite fast and easy to do if you prepare beforehand. First, you delete the default signature, then upload a PNG file you've prepared on your computer to the iPad. You can use a logo, a scanned image of your own signature or any other image you want. If you place your signature in its own folder it will only take you a couple of taps to quickly add it to any email.

    The Advantages of No-Contract Cell Phones

    If you are shy of commitments, a no-contract, no-penalty cell-phone service may be in order, particularly if you are not comfortable with having a credit check run and giving away your personal information. Traditional mobile phone service plans require a one- or two-year commitment, locking you into the plan by offering you a wireless phone for pennies on the dollar. One trade-off is that your no-contract cell-phone plan requires you to buy your phone upfront without the long-term contract subsidy.

    Where to Find Free Cell Phones

    The wireless market is very competitive, both for phones and service. Carriers subsidize phones so that you'll sign a contract for service, slashing hundreds of dollars off the unsubsidized cost of devices such as the iPhone. How low do these discounts go? It is possible to get a free phone, depending on the phone you're willing to take and your economic circumstances, but sometimes a free-phone deal that looks too good to be true is just that.

    How to Determine What Smartphone Is the Right Fit?

    When selecting a smartphone, the most important factors for you to consider are your wireless provider, the available apps, the data plans and model selection. Smartphones, unless they are unlocked, only work with a specific cell phone provider. Also, since each cell phone provider carries its own line of smartphones, they don't all offer the same selection. Therefore you should choose your provider and data plan before you select your phone. Think about the features of the phone and the applications offered, keeping in mind which you think you will use.

    How To Buy Prepaid SIM Cards

    Buying a prepaid SIM card for a cell phone or smartphone is an alternative way to pay for your mobile calls, text and data without having to sign up for a contract that locks you into a single network provider for a long period of time. Even if you have your own contract phone, you might also want to invest in a prepaid SIM card that you can give to a child or an elderly relative so that you know they will have enough credit to call you in an emergency. Electronics retail stores offer a range of prepaid SIM cards that you can buy from the store or its website.

    How to Block Text Messages

    Unwanted text messages are not just a hassle, they can also be dangerous. In September 2012, CNet reported a rash of phishing using text messages on mobile phones, luring people into providing confidential information like passwords and account numbers to unscrupulous hackers. Even harmless text messages can cost you money if you pay for each text received on your phone. Your options for blocking text messages vary depending on who your service provider is. There are two ways of sending a text message to a cell phone: through email or from another cell phone. Spammers often use mass emails to send text messages to cell phones.

    What Is a Cell Phone Data Plan?

    Modern cell phone data plans encompass more than just text. Internet browsing, music streaming and GPS functionality all rely on data access. Without the right plan, you may be shocked by your cellular charges at the end of each month. Unique to each carrier, data plans are chosen by usage amount, calculated in gigabytes. Choosing the right plan is critical to keeping the information flowing to your smartphone without breaking your budget.

    FCC Regulations Concerning Cell Phone GPS Tracking

    The ever-increasing use of cellular and smartphones alters the face of security and emergency awareness in the United States. Today, every cell phone made must be equipped with a GPS receiver to more easily locate those that cannot make outgoing calls due to injury or other impairment. With estimates placing over 70 percent of 911 emergency calls coming from cell phones, the Federal Communications Commission has comprehensive regulations regarding where calls are routed and how they are handled by emergency service providers.

    How To Buy a BlackBerry Without a Contract

    Cellular phones are heavily subsidized by the carriers, who make back their investment on monthly billing, data plans and a variety of other fees, charges and options. That takes time, so carriers typically offer larger subsidies on longer contracts. However, sometimes you might want to simply buy a capable phone, like a BlackBerry, and not take on the obligation of a carrier's contract. It's not difficult, though your upfront cost can be higher.

    How to Forward Voice Mail Messages on an iPhone

    When the iPhone was introduced in 2007, Apple also introduced "visual voicemail," which displays your incoming messages in a list. Unfortunately, the iPhone doesn't offer message forwarding. However, using a third-party service or application such as Google Voice, YouMail or Fusion Voicemail, you can forward your voice mail messages to anyone's email inbox. These services also include other features, such as the ability to check your email from any computer.

    How to Find a Lost Cell Phone Using GPS

    Losing your cell phone is no fun. In addition to losing touch with friends and family, modern smartphones contain critical personal and financial information, such as contact details and passwords. Fortunately, the GPS functionality built into today's smartphones allows lost phones to be located using a Web browser, either on a second smartphone or a laptop.

    Ways to Save Money on Cell Phone Plans

    Cell phone budgets can easily get out of hand. The carriers don't make it particularly easy, either. Between the list of major and secondary carriers, the options they present for calling plans, group plans, contract-less plans, minutes per month, data amounts per month and more, it's easy to get overwhelmed. Even worse, you might be trying to make this decision just as your old plan is expiring, and there's a lot of pressure to make the decision as quickly as possible.

    How to Read Data Stored on a SIM Card

    Subscriber identity module cards are smart memory cards used by GSM or CDMA cellular phones to store user identity, network authentication, personal security information, text messages and contact phone numbers and email addresses. SIM cards can be read by other compatible cell phones and smart card readers using special software. In order to read a locked SIM card, you should call your cellular carrier to get the personal identification number or PIN unlock key associated with your SIM card. You can then make backups of or modify your contact and text messages on the SIM card.

    Uses of GPS Tracking

    Global Positioning System (GPS) receivers work by receiving signals from GPS satellites; each signal has the time it was broadcast and the orbital information of the satellite. A specialized chip on the receiver or a specialized program in a smartphone, convert this information into a set of coordinates. These coordinates get used in a lot of ways, some of which are a little surprising.

    How to Switch Phones Easily With Verizon Wireless

    Verizon Wireless enables you to quickly change the cell phone that's associated with your account. There are two ways to accomplish this switch: You can visit a Verizon store and have the customer service make the change, or you can access the My Verizon website and complete the transfer from a computer. Both methods enable you to purchase a new phone and connect it to your existing number. This will also work with phones acquired from friends, as long as the phone is compatible with the Verizon network.

    How to Charge a Cell Phone Without a Charger

    If you rely heavily on your cellular phone, discovering that your battery is nearly dead can be a shock. All those wonderful features of modern smartphones use battery power, and your battery can fade rapidly even while the phone is in your pocket. Fortunately, you have several options for replenishing your battery, even if your charger's broken or forgotten at home.

    How to Add a Bluetooth Device to a Cell Phone

    Bluetooth technology connects your smartphone to Bluetooth-enabled devices, such as headsets, keyboards and even other phones. Most phones can maintain a list of previously connected Bluetooth devices for subsequent use, but you can only connect to one device at a time. The procedure for adding a Bluetooth device varies slightly between iPhone, Android, Windows and BlackBerry phones, but each operating system makes the procedure simple to easily connect to peripheral devices.

    The Best Cell Phone for People Who Have Hearing Aids

    In August 2003, the Federal Communications Commission established rules and standards for digital wireless phones to guarantee their compatibility with hearing aids as well as ensure the availability of acceptable models by setting benchmarks for manufacturers. These rules became part of the Hearing Aid Compatibility Act, which Congress passed for landlines in 1988. Hearing impaired cell phone users should understand the issues and become familiar with device technologies to choose the best cell phone. Consider factors that include both cell phone and hearing aid ratings, the connection standard of your service provider, assistive phone features and bridge accessories.

    How to Download Music to a Cell Phone

    Cell phones have transitioned to smartphones, and even before the smartphone transitions, they'd already consolidated several other consumer electronics devices, like MP3 players and small digital cameras.
