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

Hi, I have bought an unlocked Samsung Omnia 2 i920 online, I was told I can insert my fido sim card, however I don't see any sim card slot. I have looked everywhere. I was wondering if you guys can tell me if there is a sim card slot somewhere hidden or somewhere i did not see, please take a picture if you have one. If not then how do I choose a network to go with other then the current Verizon network if its unlocked? Please let me know. Thanks.

I saw your image, though mines doesn't look like that (is that when you took the battery out from the back?) mines the i920, I think your's the i8000. Anyways the tech support called me, since i sent the person a message about the sim slot, and he told me there isn't a sim slot in my phone however i can exchange it for another one that has one (i made a thread about it). Thanks for helping though.
RUIM Phone-without SIM
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 brought my att skyrocket to seoul so i could use a prepaid sim card. my assistant got a sk telecom prepaid sim card for my phone and inserted in my phone and upon booting up, it's asking for the sim network pin code. the card that the sim card came with has a pin code and a puk code on it which none of it works. i've already chatted with at&t and they told me the code has nothing to do with at&t and the pin code is for the prepaid card ive put in. anyone know what i'm doing wrong? is it be possible that it's because its a weekend and that monday might start working?
thanks in advance

Sent from my SAMSUNG-SGH-I727
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?
