Calls breaking up

[Guest]

I have a GT-I8190N Samsung Galaxy S3 mini that is unlocked. It is GSM capable.

When I install my 3G mini Sim and identify the IMEI to the AT&T network, I am able to call and receive calls but the calls break up during talk time and sound like they are in a tin can.

I contacted AT&T tech and they could not identify any problems with their side of the system.

There is 5 bar signal strength, mobile data is 'Edge' and working,and I have no text plan. The web browser works great and I can receive email.

Is the phone bad or is it something else?

Does this happen only when using the phone as a handset? Or, does it also happen when using a headset (wired or wireless)?

This situation happens with and without a headset. According to AT&T tech this phone is a Sprint phone and will have problems with AT&T network (BS).

I have found that working AT&T tech for the past three hours that they say there is not a problem with their network, but when I make a call from my home the called individual hears fading audio and the audio is breaking up.

Could there be interference caused by other wireless in the local?

It could be interference, but it is most likely the handset itself if this occurs everywhere.
