Mobile phones can't send text messages.

It may be that the mobile phone is poisoned, or the sequela left by uninstalling the software leads to the incompatibility of the system, which will seriously slow down the speed of the mobile phone!

If you are poisoned, the simplest and most direct way is to check the machine! ! (that is, format the phone), which is equivalent to restoring the phone to the original factory setting data!

It is best to back up important information such as business cards before the grid machine.

Soft Grid Machine: Enter *#7370# in standby mode.

If there are still files left after formatting, you can try the hard grid machine: press and hold four keys (power on key, dial key, * key and 3 key) at the same time to turn on the phone, and then release the key until the blue Nokia font appears on the phone.

I hope this helps.
