Make sure you have your mobile data turned on. On some phone models, when sending an MMS, the phone will automatically enable it until it is sent. In order to receive one, you may have to enable your mobile data from the phone's menu. Since you're unlocked on T-Mobile, it's possible that your phone supports sending MMS over standard networks, but not receiving, in which case your phone's antenna is not compatible with T-Mobile's network frequency.
Using an unlock screen is easy. Enter the code.
but, there are two types of code,
A Subscriber set pass code

A PUK Code, aka a SIM Lock
Which do you have? Click Comment.

DVD drives region settings can be changed to view DVDs from different region, but on the 4th change the DVD player will lock on the 4th region change. The DVD player can be made region free by upgrading the firmware, if it is available, but if you make a mistake the the DVD player will be a piece of junk. The best way to make a DVD player region free is to install a piece of software on the computer to make the DVD player region free.

It is very easy to do. You just follow these steps and that's it.
* Go to settings
* Go to the Privacy
* Now you will see an option "Factory Data Reset" (Click on it)
* Then Click on "Erase Everything"
after that, your device will reboot itself and it will perform an operation which will reset your data from the factory.
