Bought it off of craigslist. Whenever I put my sim in it says it needs a code to unlock the sim or can only be used with a specific sim card...
Tried going to the store and calling att and samsung.. no luck. Anyone able to help with this?
I'm going to ask it. Are you sure it's an i637 and are you on AT&T? If so, keep calling until you get the right tech at AT&T. You probably just need the P-U-K code.
I called them up and all they gave me was an unlock code <_<
I got a free Samsung Focus today, thanks to the Microsoft giveaway for TechEd, where the first 50 from TechEd who publish get a free phone. I was told that the phone was carrier unlocked... But since I'm on Verizon, I can't use it anyway. I am probably going to sell it on ebay (although I'm considering loaning it to a couple iPhone friends for a bit, so they can get the full WP7 experience), but I want to make sure it is unlocked before I advertise it as unlocked. How do I know for sure?
Also, if I do loan it out to friends, can an ATT (or T-Mobile since it is supposedly unlocked) customer just pull out their SIM and put it in here, and go with it? Or is there something their carrier needs to do?
Thanks!

Correct, you just put in a SIM card and use it. No carrier attention needed. To test if it is unlocked, you need to find a T-Mobile SIM card, or any other non-AT&T SIM card, and put it in. If it is locked, the phone will let you know immediately and you won't be able to use the phone or cell data.
Thanks. I'll have to have one of my iPhone friends try it for me. I don't know if anyone around here is on T-Mobile.
you can usually just go to tmobile and ask for one, sometimes they'll give one to you. and it doesn't have to be activated.
I bought a nexus s 4g sph-d720 on craigslist and found out it had bad esn but I want to flash to straight talk anyway. The phone is unlocked but what sim card should I get from straight talk? Will a sprint sim card work?
First things first: Sprint does not use SIM cards. CDMA phones in general don't use them. So if the carrier of choice you want to use this phone on requires a SIM card, this is not the phone for you.
Hey guys. Im a sales associate at radioshack and i had a customer come in with the Infuse and wanted it unlocked and to use with a NET10 sim card. All sounded good to me so i called AT&T. I got the unlock code for him. Them i had to call NET10 to port his number from Intelos Wireless or whatever it is. All went good. I put the sim card into the phone and done the unlock. Said successful. I rebooted the phone. It comes up and says sim car unimprovised or something. I would look for sure but the customer is not here in store anymore so i cant look. Now the only reason im thinking that im getting that sim card issue is cause the sim card is not activated yet cause the port has not gone through? What you guys think?

I currently use a Motorola Atrix HD cell phone . The Android version is 4.1.1 and it will not update to a newer version. It is probably 4 years old at least. I want to get a newer phone but really was trying to avoid signing another 2 years contract with AT&T so wondered if I bought an unlocked phone that is AT&T compatible, can I just move the SIM card to the new phone and then use it as my new phone? I am older, 75, and need help with this decision. I don't need a phone with all the bells and whistles, just a basic smart phone to call, text, do email and other basic online functions. I did go to Best Buy and selected one of their unlocked phones but my SIM card would not fit the new phone so had to cancel that. Any help, comments or suggestions will be greatly appreciated.

Yes. Switching your current AT&T SIM card to another unlocked phone will work. There are a few things to watch out for:
1. Don't forger to somehow transfer your contacts to your new phone. This can be done with Google account sync or (easier) you could export your contacts from your phone to your SIM card.
2. There are multiple SIM card sizes (as you notices). There is standard size sim, micro sim and nano sim. Make sure your SIM size is compatible with your phone. If it's too big or too small go to AT&T and ask for a different size SIM card. Just don't ever use SIM adapters. They can break the phone's SIM tray permanently.

Thanks Janekmuric. I'll have to take out my SIM card and see what type it is. Also will try to see if there is a way on my phone to put my contacts on my SIM card. So moving my SIM card to a new phone (assuming it fits) will then enable me to begin to use that phone as my normal phone. I just can't believe it's that easy and that AT&T won't have their claws in there for some kind of fee or charge. I'll have to look for a phone then and want to try to get one that is at least version 6, I think that's Marshmallow. I've seen a number of these on Amazon that are unlocked and compatible with AT&T and not very expensive. I just need as I said earlier a basic smart phone to do calls, text, email and some basic internet. I do not do streaming or use my phone for music and all that.

Good luck with finding a new phone. You can use GSMArena Phone Finder to find a phone you need. You put in what you want from the phone, what android version you want, what battery capacity, price, size and so on, and it returns a list of phones that fall into that category.
Samsung Galaxy J7 is good for what you need. It's responsive, fast, stylish and costs 220 USD on Amazon.com
