No, you cannot use the LG Voyager because AT&T uses sim cards and Verizon does. You might be able to use the LG Voyager for Sprint since they do not use sim cards either.
if it's unlocked I think so, if not, procedures all over internet
no no
Sure. As long as your iPhone model has the SIM Card slot. Just make sure your LG uses Micro SIM Cards, or else you just have to cut your SIM Card to fit.
Yes, as long as you are using ATT/Cingular. I have switched my sim card from a Motorola to an Ericsson and now im using an LG.
can att lg xpression connect to my wifi
You can't use an ATT LG Cf360 on Cricket because it runs on a different frequency, which the ATT phones do not support.
of couse it does every phone has a sim card
NO the lg muziq is a CDMA phone and therefore doesnt use a sim card, it has an sd card slot for mass storage but no sim slot
no you can not
From what I understand, The Rumor Touch does not use a SIM card.
i heard that sprint and verizon both do NOT have sim cards with the exceptions of some of the new 4g phones but this is a question that I have been wondering myself, and cant get a straight answer to myself.
