Yes as long as the phone is att and has a sim card slot
any AT&T phone that can take that sort of sim card.
Sprint doesn't use SIM cards...
yes, but i wouldn't do that. It should work on any phone including t-mobile and att
No because first of there is no slot for it and apple probably wouldn't allow it anyway
the iphone is from att and am looking to put it onto tmobile and the phone is not under contract and was under att next
Could I put a simple mobile sin card to my HTC from ATT
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, provided your ATT phone is SIM unlocked.
yes
No. And if you use the "internet" you will be charged per byte used. You will need to call ATT and select a data plan.
You can put any SIM card in an unlocked cell phone.
yes
