[Q] S3 on Bell: not registered on network

hi everyone,
I got my S3 from Bell two weeks ago, it worked fine most of the time including calls, sms and data.
but occasionally for whatever reason the phone cannot make call or send sms, no ring for incoming call also. it shows "not registered on network" when I try to dial. at the time showing this error, there was signal on the bar.
maybe after long time, it can registered itself into network again, but most of the time, I just restart the phone and it works fine again.
I called Bell and they asked me to replace the SIM card, so I did, but I still see this error. So I think it is not SIM issue.
anyone has idea what the cause could be? or is there anyway to fix it?
I tried to search online before I ask, just couldn't find a solution so far.
so post here and hope anyone can help,
thanks for the help in advance.

I've had this issue as well.

I had this problems with rogers as well. Same as you I contacted rogers they told me to remove the sim and replace it. Worked for a while but kept happening. I got fed up and rooted then installed kyan rom and haven't had the problem since. Not sure if it was rom based or if the factory reset before flashing resolved the issue but haven't had it since. Hope someone figures this out though because it's annoying especially on a new phone that is stock.

Good to hear you had fixed it.
I might try factory reset to see what happen.

Had this problem on bell a few times the first 2 weeks I had my phone. Went to the bell store and without hesitation they told me to change the mobile network mode from gsm/hspa+/lte
To just gsm/hspa+.
Reason given was the Lte network where I was using my phone (west island, montreal) wasn't strong enough. So my phone would switch between networks until eventually it got in that state. Personnaly I think the problem was more signal penetration into the computer lab I work in.
It's been 2 weeks stable so far. A co-worker reported the same problem to me last week and he took my advice and hasn't had the problem since.

Thank you very much for the tip. I was wondering that too, because I noticed that the network icon at top bar keep changing between H+ and LTE by itself. and I wonder why too.
I will try and see what happened.
thanks

SAMSUNG i747M not registered on network
I had this samsung s3 i747M from canada. Got it unlocked here in Pakistan. Placed a local sim in it. It recognizes the sim, registers it, makes calls, but then after a while, it shows "not registered on network". i restart, it registers network again, then loses it again. It keeps doing it. sometimes it is registered on network, but can't make or receive calls.
I have tried a number of things but the problem is not resolved and i'm fed up to the point that i want to throw this phone away.
The original rom had android 4.3
here's the list of things i have tried.
* changed the network mode to "GSM only" and "WCDMA/GSM (auto connect)" - NO USE
* Factory data reset a few times - NO USE
* tried a custom rom (it was so bad, i deleted it, don't even remember the name) - NO USE
* stock rom 4.4.2 from "sammobile.com" - NO USE
* tried flashing different modems from "http://forum.xda-developers.com/showthread.php?t=1831898" - NO USE
* tried changing the options from *#2263# to my network's specifications - NO USE
* tried sims from different networks - NO USE
PLEASE IF SOMEONE CAN HELP ME OUT HERE, I'M DESPERATE

@qamar_ish, what ROM is on your Samsung phone?

Originally it came with android 4.3. Currently it has this kitkat rom, which i downloaded from "sammobile.com".
the filename is this:
I747MVLUFNK2_I747MOYCFNK2_I747MVLUFNK2_HOME.tar.md5
It said on the webpage that it is the stock rom for SGH-i747M

Does your carrier require an AWS-compatible phone? Does the i747m support all frequencies provided by your provider?

I'm not sure about whether an AWS phone is required or not. But it certainly supports all the frequencies provided by the networks here. I checked it by using the code *#2263# and the options have the frequency supported by my networks here, that is "ufone" and "warid"
PS. I'm not an expert on this thing, whatever i'm doing, i learnt it during the last week..

It looks like your phone does support your carrier's frequencies.
Does your phone show the imei# from the dialpad? Is it possible there is something wrong with the phone's imei #?

It does show the correct imei when i dial *#06#. It had lost its imei initially when i got it unlocked, but got it fixed from someone.

Do you know why it lost the imei during the unlock process? Does the imei # in the phone match the imei # on the label under the battery?

I dont know how it lost imei. The guy who fixed it said that the imei is corrupted and he fixed it. Now it shows the same imei as on the back of the device.

I have never had a Samsung phone lose the imei if the phone was unlocked using a code, assuming that is how your phone was unlocked.
Did you try re-injecting the imei with the efs folder? It can be done using nvwriter.

Ok. I will try that. Can u guide me how to do it? Or share a link or something.
And thanx for helping me out here man..

its rooted i used the galxsim from play store to unlock it
checkout the pics can someone plz explain why an unlocked phone wont work with other sims ?

Remove your IMEI number from public eye.
As for the problem call network operators to say why isnt working on their network.

iv been told that if i flash a different bootloader that would unlock it can someone plz confirm this for me plz tia

anybody got any idea plz iv tried everything

Hi terry1256
I'd suggest flashing a new rom as most non stock roms are unlocked. Or search xda for info on unlocking your phone and follow it. Just be patient and stay calm and you'll get it sorted mate.

Try using baseband 72 or 86 or 66
one of them replies 100%

Does it happen only with your phone? Could it be due to operator's low signal in that area?

Im solved problem by testing. Before Im really think its my phone number, change carrier three time.
All are fine it I do all with install custom rom. It I install kernel next full reset/wipe data next rom all work wellcome. But after im change kernel its happen again.
Thanks for any advice. Subject can be closed.

SGSII wont connect to T-Mo

So had a SGSII, flashed to CM 10.1.2. It had been working before and it had worked last week to call but didnt use it because data wasnt added onto that line yet.
This week, put the sim in, i see the signal bar greyed out with bars.. then empties out again.. it just keeps repeating this... like it wont connect. i tried that SIM card in another phone.. even another SGSII, both work. just this specific SGSII doesnt. I put another sim card into this SGSII, does same thing. I've tried clearing cache/restore to factory and flashing new rom. but doesnt work either
anyone have had this problem before?

sounds good. ill try when i can. what does it mean if its blacklisted? any way to get it off that list?

blacklisted = meaning someone sold someone else a phone and waited a few days/weeks/maybe even months to call tmobile or carrier and report there phone stolen or lost aka IMEI shutdown .....now they (the seller) profit 2 ways a new phone from carrier and then cash from the buyer

oh no we didnt do that. the phones are all ours. just being passed from person to person. we never called tmobile.

ok so then like @soupysoup said you should check your baseband(RADIO) and make sure the last digits are MC6 for the radio flash this see if your signal comes back http://goo.im/devs/Void_Dweller/SGH-T989_UVMC6_radio.zip

woo flashing the radio worked O_O

[Q] Emergency Calls Only - Still get 3g but no cals

Hi guys, I'm new to this forum, the reason i've joined is that my Galaxy Note II has a major problem with it...
Early august I rooted it, but then put it back to it's original ROM, it was working fine for a week or so, and then it wouldn't make any calls.
I can access 3g, used a different SIM card Three and it does the same thing. I've rebooted it from scratch about 4/5 times.
Today I found it in my drawer and wanted to try it again, I put my SIM card in and the same thing still happens.
Any suggestions?7
My
AP: N7100XXDME6
CP: N710XXDMF1
CSC N7100XXDMF1
My screen is cracked at the top left corner of the phone, at first I thought I might have broken the aerial, but then how would my 3g work?
Thanks!

So what happens when you try to make call? Does it say not registered on network, give a different error message or something?

It says "not registered on a network"
Thanks.

What about your IMEI ? Most probably it will be fine as you still able to use 3G. In certain when IMEI is correct and you are unable to make Call, possibilities are
1.Device get banned due to tempered IMEI (usually happens if you have purchased old and may be stolen)
2.Network locked.
Talk to your operator about these.

Hi Thanks for the reply,
I did buy it from the market, it can't be locked as it doesn't work on a different carrier so I don't know why that would be?
Can you change the IMEI number on the device at all???

Best not to ask this question.
Changing the ID of a phone IS ILLEGAL.

Dr.ketan is the expert but, as long as your phone is not blocked. whenever I get that error, I simply go into settings do a network search and then re register on my network. I presume you've tried that already?
