The technological invention of AT&T provided a base for the world’s telecommunication industry. AT&T also makes use of the GSM technology.
Effect of carriers on unlocked mobile
- A locked GSM phone can be unlocked using a unique code, and the operator can be changed.
- AT&T uses GSM carriers, but Verizon and Sprint have CDMA carriers.
- Since AT&T and T-Mobile use the same carrier (GSM), you can use it with T-Mobile if you unlock a phone from AT&T.
- The CDMA carrier is more restrictive. So unlocked phones from Verizon cannot be used with sprint.
- Before unlocking the phone, one should check whether it is compatible with other carrier networks or not.
What do you mean by a locked AT&TPhone?
The primary reason cell phones are locked is to keep users under contract. For example, if you are an AT&T Mobile user, you will contract with an AT&T Mobile wireless carrier. Under the contract, if you purchase a new phone, the cost of the phone will be broken up, and it will be added into a two or three-year contract.
This cost will be divided into EMIs, and it will be adjusted into the monthly bill. It will be in addition to service charges. Under such circumstances, the phone will be locked with AT&T Mobile wireless carrier.
If you wish to change the carrier, you should request unlocking your cell phone. You are generally unlocking the phone means you will have to pay extra to remain out of the contract.
