Not registered to Network

I bought this unlocked Samsung Galaxy Note II about 9 months ago, and it worked perfectly. All of sudden, it stopped recognizing the network. It keeps saying that it's unable to connect, but it can recognize T-mobile signals. It looks like the phone knows that there is a signal but is unable to connect to the network. Everything on this phone has worked very well other than this network problem. I can use WiFi perfectly, but I cannot make or receive calls. Would you please help me? Thank you so much.

Answer this question I have this problem too

Is this a good question?

Easiest, but not likely: your SIM is shifted or the contact continuity has degraded. Shut off phone, pull out sim and check condition of contacts on SIM. I've had to clean a really old and corroded SIM with the eraser on a pencil before. I stuck the center of the eraser over each contact pad on the SIM and gave a dozen or so back-forth twists to rub the oxide buildup away, repeating in a grid pattern to cover the entirety of the contacts. Once done, blow off any loose debris and pop the SIM back in and give it a go., Pay attention to SIM pad to phone contact alignment, particularly if you're using a cut down full size SIM, also.

IF that doesn't work, there's another common, but really annoying firmware corruption issue that occurs somewhat often:

1. Go to the phone dialer and enter *#*#4636#*#* to pull up the hidden testing menu.(4636="INFO") and the menu should pop up as soon as you press the last * key, without having to hit dial.

2. pick first menu option "Phone information"

3. The first line on the phone info menu should be IMEI. Compare it to the IMEI printed on the label under the battery.

If they don't match, it's likely that the IMEI from the menu got overwritten or corrupted somehow.

At boot, Your kernel pulls a config file from a factory-programmed, device-specific config file in the EFS folder on the root of your internal stoirage. If the EFS has bad info, the IMEI will get set to a single, specific value that is the same on every GN2. I don't remember the valyue offhand, but it's mentioned on XDA a few times in the forums.

Hopefully, you have a backup of default and proper EFS partition handy that you can restore in recovery mode.

Barring the existence of a valid backup, I think there are a few, complex methods to flash a generic stock image via ODIN, then you can go into root explorer and manually update the file(s) with the appropriate values.

I had this happen anout 2 weeks ago and freaked out because I couldn't find an EFS image backup in CWM recovery. After about a day of dinking around with no success, I realized I had a TWRP backup from when I first rooted the phone, so I restored just the EFS partition image via the advancved backup menu in the PhilZ CWM recovery.

After flashing and rebooting, the SIM got provisioned on the network, but my phone app and gvoice kept crashing. I updated my to a later, fresh version after doing a cache/dalvik/factory wipe from recovery and it's back 100% now.

Update

Make sure you're flipping the # and * characters on both ends:

*#*#4636#*#*

start: * before #

end: # before *

There are a lot of reasons you may be facing the not registered on network problem . These are

1 Nulled IMEI Number

2 No Service

3 Unknown Baseband

4 Outdated Firmware

5 Radio is off

You can check your IMEI number by dialling * # 0 6 # , you will see 0000 or nulled if it's corrupted.

If you have an Unknown baseband then i suggest your to backup and restore your EFS Folder.This folder contains all the information about your phone.

Simply go to settings , then go to about, then hit the update button.This will update you to an higher OS version

If your radio is off , dial *#*#4636#*#* . Then click Phone Information.Run a quick Ping. After, Turn Radio OFF/ON

Is it not taking any network signal or it seldom takes and sometimes doesn't take? If it is not at all connecting to any network then it can be software issue but if it is switching between getting or not getting signals then it be a hardware issue aswell
