“Can I use this in India since there is a AT&T logo on back of the phone? Hi.. I Purchased "Samsung - Galaxy S III 4G Cell Phone (Unlocked)" phone dated Jun 29 to send it to India.. but I can see AT&T logo on the back of the phone. Can I use this phone in India with India Sim card from any India service providers? Or I have to use only in US with AT&T network. Please let me know whether I can use this in India or not?”
