I am almost positive that you will be able to use that SIM card. I was told that any At&T; card can work in any At&T; phone. However, if the one phone is not 3g, then you will have some limitations. Since you are going from 3g to 3g, you should be ok. I was ok when I switched over to this phone. I had an intermediate phone that was AT&T; that was not 3g, i could not make international phone calls. So, I got this Pantech and am getting international phone call capability.

I don't see why not. But I'm not an expert. To be certain, you really need to talk with one.

yes, i just got mine from Amazon and put my sim card from my other phone in and got message that 50 dollars was added to my gophone account, phone is great , you need to be a att customer for at least 4 months it says for upgrade.So you should be ok Just dont put new sim card that comes with it. use the one you already have.

I say yes because I am using mine with AT&T.; If you have a really old AT&T; SIM Card, you can get a newer SIM Card from an AT&T; store, probably for free. I got significantly better coverage than with my previous Nokia phone on AT&T.; I suspect it is because it is quad-band and the other one wasn't.

Yes... But you need to get a new sim card and activate it by calling AT&T enjoy your phone

Yes, I used the one I had from my LG A340 flip phone.The provider you use should be able to provide a card for the phone. But check with the provider.Not all providers will accept this phone.

As long as you have a micro-SIM card you can just pop it in and select your network to connect to (it auto-detected correctly for mine but you can verify through settings). If you don't have a micro-SIM card then just swing by your AT&T; store and ask them for one, they'll hand it to you over the counter and get your account flipped to use it. 5 minute process. Enjoy the phone!

We have AT&T; service and I just placed the Sim card from my husbands old phone into the Just5 phone. No problems what so ever!

Yes. Call AT&T; customer service and tell them you have purchased the phone to replace existing phone. They will ask for Pantech phone info (ID #, etc). Can use your existing plan, but will need to add Data Plan ($20/up) to use the mobile data feature when WiFi not available. You should be able to use your existing SIM Card from old phone also. I did all of above.

I used this phone with AT&T.; Just took the SIM card out of the existing handset and popped it into this phone.

As far as I know the RM-937 which I have is the "international" version.... mine was unlocked and all I did was get a nano lte sim card from my provider and worked fine.... I guess you would have to do the same, tell at&t; you have a unlocked phone and you need a sim card they should be able to help..... hope that helps......

If you have an AT&T; phone right now, you can swap your sim card from your old phone to the new one. The store will do it for you, but look up on the internet on how to swap sim cards. It's easy. Your account will not change.

Yes to both questions. I've had one for about 14 months and it arrived unlocked and ready for my SIM card. But be sure that the frequency bands it offers are compatible with your needs. For use in North America, this phone has the 1900 mhz band for both calls and 3G data. That's compatible with most of AT&T;'s coverage area and some of T-Mobile's (only large cities at this juncture), but not every single square inch of either. Checking the applicable coverage map will answer that question. I hope this was helpful. :)

Hello Timothy,You should be able to, but I am not 100% certain of this since I do not have experience with doing that. I've only used the same phone to switch sim cards and to a new prepaid plan. There is a lot of info online how to unlock this phone. Please ask AT&T; regarding your contact and if this is possible to switch phones. Thanks, Nathaniel

I have not used this sim card for that exact phone, but I have used these sim cards on numerous AT&T phones. Just make sure the sim card is the same size because they do vary. Once you have that all sorted out just activate the card with your new number and you will be good to go! As far as additional charges... NONE unless you choose add on features like Data (for downloads outside of wifi) etc.. Hope this helps:)

the 3G network of AT&T is WCDMA, and this phone support WCDMA, so it will still work with your SIM card
