Well.....I don't have the T610, but my friend does. He lives in Houston (near my house) and so far.......his reception isn't very good...the phone only have like.....4 bars...i think....and most of the time, there's no signal. Plus, whenever someone tries to call him, it goes directly into his voice mail while he have signal and full battery! it's weird! but then again, that happened to me when i was in Sprint with the Samsung A460 also...so I don't know if it's the phone or the network or what....hope this helps.
