I've a SE W350 (At&t). Currently i'm in India. Last week i unlocked it from a service guy. After unlocking it works only with one provider, Vodafone. It does not work with other providers like Airtel. The frequencies for the providers in my area are -
Airtel - 900
Vodafone - 1800.
Its a Quad-band world phone - 850/900/1800/1900 MHz. Could you please help me fix this problem?
same thin with me I called AT&T and revceived the code which unlocked the phone but I dont see Airtel network. I see only Vodaphone,Tataindicom.
Any one please help us!
I think because your handsets are W350a (does not operate 900Mhz frequency)
You need W350i or W350c
W350i - 900/1800/1900 MHz for Europe
W350c - 900/1800/1900 MHz for China
W350a - 850/1800/1900 MHz for America
Before buying i checked to ensure that its a quad band phone! Is it not? Still AT&T says its a quad band phone on their site?
No, it's a tri-band phone. Probably AT&T means it can operate at all frequencies.
