Hello folks,
A while back, I managed to get AT&T to block network data on my mobile line.
Shortly thereafter, I purchased an unlocked HTC Touch in Europe and experienced no problems receiving/making calls in the U.S. Inserting my AT&T SIM was plug-and-play, for lack of better words.
During a recent trip to Europe, I purchased a Samsung Galaxy S4. After inserting my AT&T SIM, I can not receive/make any calls.
I have bars, get a Voice Mail notification, as well as a 'Not registered to network' message. I am also unable to register to the AT&T networks the phone searches and finds...
Any feedback will be greatly appreciated!
apn settings would not stop registration.. maybe the phone was a black listed imei that went to europe and you bought it and are trying to use it here.
what is the model number.

you got screwed dude. the phone has bad esn and they blocked the phone already. sorry to hear
Isn't this the "region Locking" that Samsung has been getting flack for lately? If you buy a phone in EU, you have to register it in EU with an EU SIM (Any EU SIM if it an unlocked phone) initially. After that, I think you can then use ATT SIM if the phone is unlocked. It doesn't always work though and people are mad
I am assuming you bought an unlocked phone in EU
Google "SAMSUNG Region lock"
Could be the radio IC blown. That's what happened to my phone, which has a perfectly-fine IMEI (not blacklisted).
See this thread. I'm about to get my phone back from the factory today.
OK, so I bought a Samsung Galaxy S5 from an friend of mine, and found out that it was from a different carrier than my phone before this one, (which I still have and could use if this can't be fixed) the S5 is from AT&T, and I usuall do Virgin Mobile. I know that when I put in my old SIM card it will ask me for a SIM key, which I do not have. My question is, is there a way to get the SIM key, or do I have to have access to my friend's AT&T account in order to get it? People say I have to call my carrier to get the key, but I'm not sure if that is how it works. Thank you in advance.
OK sounds good. But I heard that you can contact the network it came from to get it, or is it the network your SIM card is from? If it's the company the phone came from, then it would be AT&T, and would I need to have my friend's at&t account in order to get the Network Code? If that's the case, then I'll just have to use the website you gave.
Is there any way at all to get Wi-Fi calling on an S5 with Verizon?
I bought a new S5 to replace my existing one because I thought Verizon brought that to the S5 some time ago, or so I heard online.
But the phone came with Android 5.0 build# DONGCHAO.A816 with a 15xxxx CID and no sign of Wi-Fi calling.
So my understanding is that the 15xxx CID allows unlocking the bootloader, from there is there any update I can move to with Wi-Fi calling (preferably also root)?
Or even another ROM, like CM? Or is it strictly locked out by Verizon?
Did I jump the gun and buy a phone that isn't going to do what I need?
Hey everyone!
I am about to purchase a Samsung Galaxy S8 (Unlocked-US G950U), and was wondering if the mobile hotspot feature works even if the carrier does not authorize it to (as they must if you're on a carrier's phone & unrooted). I am on the AT&T New Unlimited Plan and they don't technically allow tethering. I am wondering if this phone will block the feature as it would if it was a carrier's phone (as if was purchased through AT&T). I assume it should work without authorization as it's an unlocked phone, however I want confirmation. I contacted Samsung and they didn't want to give me a straight answer.
Thanks!
Hello all!
I bought the Samsung S7 phone in unlocked condition from eBay in US. Then I had to move to India for work related purposes and I was able to use the phone using an Indian sim. The phone developed charging issues and it was not charging. So I had to send it to US where Samsung changed the motherboard. Now, I received the phone which is working but it shows invalid sim if I put any Indian sim. It seems Samsung have restored the phone to original settings which is locked to Sprint network. Samsung tells me to contact Sprint. While Sprint says that they need the account details or confirmation from the person who bought the phone from Sprint. The eBay account from which I got the phone does not exist anymore.
I think I need to unlock the phone so that I can use other sim in India. Could anyone suggest what could be done here?
Thanks!
