Why does T-Mobile lock your phone?

  • The major reason cell phones are locked is to keep users under contract.
  • If you are a T-mobile user then you will be under contract with T-mobile wireless carrier.
  • Under the contract, if you purchase a new i-phone then the cost of the i-phone will be broken up and it will be added into a three years 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 the T-mobile wireless carrier.
  • Now if you wish to change the carrier then you should request for unlocking your cell phone.
  • Generally unlocking means you will have to pay extra to remain out of the contract.

What do you mean by a locked phone? 

  • A locked phone is a mobile device that is tied up with a particular mobile carrier network.
  • If you purchase a new cell phone under some contract then it is a locked phone.

Are all cell phones locked?

  • All cell phones are not locked. The cell phone purchased from a carrier under some kind of contract is locked.
  • But if you purchase a phone directly from the manufacturers, it is unlocked. In this case, you can easily switch from one carrier to another.

Basic Meaning of phone lock code 

 A unique code used to prevent any unauthorized person from using a phone is called a phone lock code. A typical default code is the last four digits of your phone number.

  If a service provider locks a cell phone, such a device is programmed with some unique codewords. Due to this, the Device will not operate with other wireless operators.

Difference between locked phone and unlocked phone

  • In the case of a locked phone, there is an inbuilt software code.
  • This process of inserting a software code is called encoding. Such locked phones are also said to be encoded cell phones.
  • This code prevents getting services from another carrier.
  • So if you purchase a locked phone from a T-mobile carrier and if you insert another SIM then it will not be activated.
  • This is because the software code allows the signals only from T-mobile carriers and net from any other carrier.
  • On the other hand, for an unlocked phone, there will not be any software code.
  • Even if there exists a software code for an unlocked mobile, you will get some other code that unlocks the original code.
  • This procedure of unlocking is called decoding. 

Advantages of getting the phone unlocked

●   The important prime benefit is that you will not be stuck up with the same wireless carrier.

●   If you have an unlocked phone, insert another carrier’s SIM card and then proceed to sign up with new services. But you need to check the carrier compatibility.

●   In this case, you don’t have to buy a new cell phone for a new wireless operator.

●   So, you can think of getting the cheapest services using the unlocked phone.

●   This provision is more beneficial if you are traveling abroad.

●   Replace the SIM card, insert a local carrier SIM card and start using the service.

●   In this case, you will get a new local number. Using it, you can make calls and access the internet. It will be much cheaper.

●   Usually, unlocked cell phones do not have unnecessary apps.

Are there any drawbacks of an unlocked phone? 

  • The unlocked family device might not work with full functionality on another carrier’s network, because of differences in carrier technologies.
  • T-mobile does not take any responsibility for any such limitations in the service while using another provider’s networks after the phone is unlocked
