Hi!

We are still not sure that it is your handset, If you are using two different phones with two different network mode, that could be the problem. If your phone (able to send messages) is using 2G (GSM) signal, that's fine. And your other phone is using 3G-3.5G (UMTS) signal and you are not able to make a call or even send text messages, then, that could be it, you have to switch its network mode to 2G (or GSM mode) because with 3G, the more mobile uses the signal, the lesser the coverage.

Cheers!

TO BROWSE AND DOWNLOAD WITH 3G SPEED JUST MAKE FOLLOWING CHANGES IN SETTING.
1.FROM THE MAIN MENU OPEN SETTING OPTION.
2. GO IN NETWORK SETTING.THERE WILL BE THREE OPTION AVAILABLE
NO.1 GSM
NO.2 DUAL
NO.3 UMTS
SELECT THE OPTION OF UMTS AND SAVE IT YOUR PHONE WILL BE RESTART(OPTIONALLY)
NOW YOU ARE DONE.
ALWAYS USE FIXYA TO FIX YOUR PROBLEM.
