I have had my Galaxy S 4G for about a month now and suddenly yesterday, I stopped being able to make or receive calls or connect to the data network. When I try to make a call it says "not registered on network." I see a few other people have had this problem, but I haven't found anything that has resolved the problem for me in the forums. I have tried restarting my phone and removing/reinserting my SIM card with no luck.
Some details that may or may not be relevant:
1. I was potentially in a roaming area two days ago. Yesterday, I was able to get data service on my phone at least. My one incoming call late yesterday went straight to voicemail.
The only fix I know of that you could try would be:
Go to Settings -> Wireless -> Networks/Mobile Networks -> Network Operators
and see if T-Mobile is an option. If it is, select it. Or you can try the Automatic option.
See if this does the trick. If not, stop by a local T-Mobile USA store and see if they'll let you swap the SIM, although that seems to be a bit extreme for this particular error.
Hope this helps.
On the Network Operators screen, I don't see any networks to select. When I tell it to search for networks on that same screen, I get an error: "Error while searching for networks."
I am also experiencing this same issue. When I try to make an outbound call, it says "not registered on network".
I have resetted the phone to factory settings and removed the batter and SIM for more than 15 minutes.
When you search and gives you that area means one of the following:
There is absolutely no T-Mobile or att like coverage there (tower down)
Problem with the Sim card (try a new one)
Problem with phone software (try master reset)
Were any of the suggestions helpful in resolving your issue? If so, let us know!
After a few calls to customer service, they were finally able to tell me what the problem is: the phone's IMEI number is blocked. I was able to return it and get a new phone, which is on its way and hopefully won't have any problems. Thanks, everyone.
I got this T-Mobile phone from a friend brand new. Samsung Galaxy S 4G, Unforunatly I don't think I can take mine back like you can. What is an IMEI and is there any way I can fix it myself?
I've also called T-Mobile customer support and they couldn't resolve the issue.
It says (Searching) or (No Network)
When I try to make calls it says "Not registered on network"
I've tried everything! I love this phone so much but it stopped working for me after about a month.
I just recently had this problem.
It fixed just like was said above:
1.Settings -> Wireless -> Networks/Mobile Networks -> Network Operators
2. Automatically it starts searching for a network
3. After that there is a sign - you are registered.
4. In the end I took my sim out and put it back.
