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, I've been with Virgin Mobile, a prepaid subsidary of Sprint for a few years now. Virgin Mobile phones don't have SIM cards, so I've never delt with those before. I found out that T-Mobile has a prepaid service plan for the same price as my current plan, and I am wanting to switch over to them because I feel that Virgin Mobile has an appalling lack of good (or decent, for that matter) android phones. Here are a few of my questions:
1. Can I use a T-Mobile SIM card in any Unlocked phone? Even phones on another carrier such as Verizon or AT&T?
2. Is there a difference between T-Mobiles Pre-paid SIM cards and their contract SIM cards?
3. Would I have to get my phone / SIM card unlocked before I can use it in another phone?
Thanks for any help you can offer me.
Bump?

Perpaid sim cards do not differ from contract sim cards.
Your sim card will work in most unlocked phones from other carriers. Verizon uses CDMA technology, and does not use a sim card, but they do have a few world phones with sim card slots.
I've never used a prepaid plan, so I'm not sure as to which devices will be compatible. From what I understand, (I could be wrong), iPhones and Blackberry devices are the only devices not compatible with prepaid sim cards.
Hope this helps. Good luck!

So...I have a company phone with Verizon and they (my company) won't let me activate an Android on my line.
My BlackBerry has a SIM card (and since I don't quite understand how factory SIM cards work, so...), can I just buy an Unlocked Sensation and stick my SIM card in it?
Thanks...
I don't think that's gonna work. Sensation is GSM phone, but verizon uses CDMA. It's not compatible.
Dang it...forgot about that...
Hello, I brought a HTC HD7S unlocked version from Amazon. When I first got the phone, I put a AT&T prepaid sim card into the phone, it works well. However, because I need to modify the Live ID, I reset the phone to the factory setting. And then, bad things happened. When I put a AT&T prepaid sim card, it said, the SIM card is missing or invalid. When I put another AT&T prepaid sim card, it still did not work. However, when I put a AT&T family plan card into my phone, it works well. So what`s the problem and how can I use a AT&T prepaid sim instead of the family plan sim card ??
Best wishes for everyone
Help anyone who knows the answer . Thank you so much
I read on this forum that the at&t sim card from straight talk would work for my unlocked phone only to find out that it wouldn't and now my number is ported to straight talk and I have no phone to use it for. I went to at&t store today and they plugged in my sim card and it asked for 17 digit number i think and he said it wouldn't work and I was just googling it and it seems like unlocking a cheap phone from the at&t store would work. This is very frustrating for me because I can't just call at&t and ask what there cheapest phone is and google it to see if it can be unlocked and will work because I have no phone and I also can't go to the store and simply google the phone product number to see if will work because I have no phone. any help would be greatly appreciated.
I really need help I'm very stressed out can someone help me? is there a store I can buy a phone from that will work?
What kind of phone did you put the Sim card in? Maybe you put the AT&T Sim into a phone that only uses T-Mobile bands.

I'm heading to Europe in a month and plan on using a European sim as I don't want to deal with Sprints free slow internet and $25 a week is more than I want to spend. Sprint is telling me my phone is unlocked (and I was under that impression years ago) but I want to be absolutely sure before I leave due to issues I've heard people have with Sprint phones. When I do the UICC unlock (with the Sprint sim still in), the phone tells me it can only be used with Sprint and to contact them. I called Sprint and they told me it is saying that because the Sprint sim is in the phone and the phone will work when another sim is added. I want to test my phone with my friend's at&t sim card. I really don't know squat about sim cards considering I've been a Sprint user my entire life. Therefore, I'm wondering:
1. Can I just turn off my phone, put the at&t sim in, reboot, and see if things work to test that the phone is truly unlocked?
2. After I'm done testing, can I put the at&t sim back in my friend's phone, and my Sprint sim back in mine, and have things go back to normal, or will this somehow screw things up with his phone or mine?
