Here's my question, I hope someone knowledgeable will help me out: I'm going with Net10 soon, but am looking at an LG Optimus L7, factory unlocked- lots on Ebay and Amazon. These phones are GSM 850/900/1800/1900, and
WCDMA (UMTS) 900/2100, unbranded. I want to use AT&T towers in my area. If I buy an AT&T compatible SIM card from Amazon (NET10 doesn't sell them in my area anymore), and stick it in this phone, will I get full service? I'm mostly concerned with 3G. I've gotten various answers from several people, and am pretty confused at this point!
