i have a problem with my communication. my phone is xperia mini pro, i have problem with my sim card's signal. it is always up and down, and sometimes it has no signal (emergency calls only). First i thought that this problem comes from my provider. but a few days letter, i do a test, i move my simcard to my father's phone, and the signal is always full, if down it is only get down 1 bar only. and it never lost the signal. so what is the main cause of my problem? hope you can help me.
