I looked at Nokia's phone page and apparently none of their feature phones will operate in the USA since they are all dual-band GSM 900/1800 MHz phones and most of them are 2G.The important thing to know about the 3310 is it will not work in the US.
AT&T pulled the plug on the their legacy 2G GSM network at the end of last year. I have two old handsets that will no longer register using an MVNO's SIM that uses the AT&T network.
