Unlock phone gsm: Unlocked Gsm Phones : Target

What does GSM, Lock & Unlock Mean

The term GSM means – Global System for Mobile Communications. It is the most popular standard for mobile phones in the world. GSM differs significantly from its predecessors in that both signaling and speech channels are Digital call quality, which means that it is considered a second generation (2G) mobile phone system. GSM is an open standard which is currently developed by the 3rd Generation Partnership Project (3GPP).

From the point of view of the consumer, the key advantage of GSM systems has been higher digital voice quality and low cost alternatives to making calls such as text messaging. The advantage for network operators has been the ability to deploy equipment from different vendors because the open standard allows easy inter-operability. Like other cellular standards GSM allows network operators to offer roaming services which mean subscribers can use their phones all over the world.

To help you further understand, GSM is simply a standard used by phones to communicate with each other. It is a new standard that has been adopted to all new models of phones and is now so prevailant that it has become the ‘norm’ in the phone world.

Now to answer your other question, with respect to locked and unlocked phones. A phone is locked when it is attached to network. For example if you go to AT&T and purchase a phone from them then that phone is said to be locked unto the AT&T network and as such it cannot work on another network such as SPRINT or NEXTEL. Thus an unlocked phone is a phone that is bought, that is not locked to any network. And as such it can work on any network.

The network it will lock unto will depend on the SIM card you put into the phone. For example if you put a AT&T sim in an unlocked phone then it will work on the AT&T network. In the same way if you put a NEXTEL SIM card in an unlocked phone then it will work on the NEXTEL network.

However if the phone is locked to a particular network, like say for example AT&T then changing the SIM card in the phone to another SIM card from another network such as NEXTEL will not work. This is because the phone is locked unto to AT&T network and as such will not work on any other network.

Yes, you can use the prepaid SIM card on the phone once the phone is either unlocked or on the same network as the SIM card you are going to put into it. It should work just fine.

Unfortunatly is isn’t possible to have more than one phone on the same line. It is possible to have more to than one phone on the same account, in fact, some providers will allow many many lines on one account.

The reason why your unable to do this is that your phone has a ESN (electronic serial number) that assoicated with that line. What this does is allow your network to send the calls to your phone. If there is more then one ESN per line then it will cause problems receiving calls.

For example, I had a phone that i wasnt using anymore when i bought a new one, well my old phone was recieving text messages that my new one was supposed to get, but the new one would get all the calls. To resolve the issue that had to erase the programming on the phone.

Benefits and Questions Before Getting an Unlocked Phone | Articles

Consumers have more freedom than ever when it comes to buying a smartphone and choosing a wireless carrier. Most mandatory-length contracts are a thing of the past, as is sacrificing your cell number when transferring carriers. Only one big barrier remains — the locked smartphone.

A carrier-imposed “lock” is a software code that prevents your phone from working on another cellular network. With an “unlocked” phone, on the other hand, you can get service with any carrier on a compatible network — and that’s just one of the benefits of an unlocked phone.

What are the differences between locked and unlocked phones? How can you tell if your phone is locked? And are unlocked phones eligible for the Verizon BYOD program? We have the answers.

Locked vs. unlocked phones.

There are a couple of benefits to purchasing a locked device. First, it is generally sold at a discounted price. By having you agree to stay on their network, the carrier subsidizes a portion of the cost (or bundles it into your monthly subscription rate).

Also, locked phones prevent theft. Unlocked phones are more likely to be sold illegally or used overseas with different carriers. Verizon locks its new phones as a security precaution. (Users can unlock them; more on that below.)

Although locked phones remain the most prevalent in the U.S., unlocked devices are growing in popularity for a few reasons:

• Freedom and flexibility: You can use the same phone with any compatible carrier, allowing you to switch providers and plans as desired to secure the best coverage areas and rates. 
• Resale rates: You’ll typically get more money when you sell a used, unlocked phone because buyers know they have more choice about where they can use it.
• International savings: When traveling abroad, you can activate your unlocked device with any foreign carrier that’s compatible with the phone’s technology. This allows you to pay local rates rather than roaming charges (or have a phone that doesn’t work at all).

Unlocked phones are often considered a good option for international travelers. They may also benefit anyone who likes to frequently upgrade phones — you’re free to buy a new model at any time. Forgoing carrier discounts means you pay full price for an unlocked phone, but you can also sell an older unlocked device to help offset the cost of a new one.

The best unlocked phones.

“Unlocked” doesn’t always mean universal. In fact, some phones are only compatible with GSM or CDMA networks, while many others allow for connectivity on both.

The best unlocked phone is one that can switch to any service provider. Check which networks a device supports before you buy or you could wind up with an unlocked phone that doesn’t offer as much freedom as you hoped. (The Moto G7 Play, Sony Xperia XZ2 Compact and Samsung Galaxy Fold are all examples of unlocked phones that are certified to work on Verizon as well as other networks. )

Does Verizon support unlocked phones?

It’s illegal in the U.S. to unlock a phone without the carrier’s consent, so never pay a 3rd party who promises to hack the lock code. But don’t worry — carriers must give the code to consumers at no cost, so long as they meet certain criteria.

Among wireless carriers, Verizon provides an unlocking policy that’s both generous and straightforward. To combat theft and fraud, Verizon locks all prepaid and postpaid devices for 60 days (check out the full Device Unlocking Policies). After that time, Verizon automatically removes the lock and will not lock phones again at any time.

An exemption to Verizon’s 60-day lock period is provided to military personnel who receive relocation orders outside of Verizon coverage area. In this case, contact Verizon’s Customer Service to unlock a device at any time and suspend service.

The Verizon BYOD Program (Bring Your Own Device).

Have an unlocked smartphone you own and love? You bring the phone, Verizon supplies the plan — and a $250 prepaid Mastercard when you switch (plus another $100 if you switch your tablet, too).

Activate your existing eligible smartphone on a new Verizon prepaid or postpaid plan, transfer your number from any wireless carrier and then visit vzw.com/digitalrebatecenter to redeem this special offer within 30 days. 

To ensure voice and data work properly, only select BYOD devices with approved hardware and software for use on the Verizon Wireless network. To see whether your unlocked phone meets the criteria, check our Bring Your Own Device page.
