Nokia mobile phone can't receive SMS.

Soft Grid: After entering *#7370# on the mobile phone, the lock code is required. The initial password is: 12345. If you have changed your mobile phone password, it is the changed password (not the password of the SIM card). After that, a white screen will appear, showing only the words Nokia, which will be completed in 3~5 minutes. After the grid is completed, re-enter the mobile phone time; 2. Hard grid: Turn off the power first, press and hold the dial key, * key and "3" key while turning on the power, and turn on the power until the word "NOKIA" appears. You can't release any keys during this process, just wait a few seconds until the words "Formatting ……/" appear, and then release the key. After 3~5 minutes, the system is formatted, the mobile phone automatically restarts to enter the standby screen, and the mobile phone time is re-entered; 3. Through the software grid: Install the SystemTools software, which has formatting options and can grid the machine without entering the lock code.
