Hi all,
sometimes my Mozart welcomes me with the enter SIM PIN dialog, although the phone was not turned off over night (typically, the phone is charging at night).
This problems occurs sporadically, I'd estimate once a week. I did not find any correlation with the usage pattern, i.e. with apps I was executing.
This issue is very annoying, as I'm not available by phone for hours (I don't expect calls at night regularly, but it is still unacceptable due to emergency cases).
Did anybody notice the same problem?
Thanks very much for your info!
Update: I have a T-Mobile DE device updated to firmware revision 2250.09.12505.111 and radio version 5.50.09.18_22.24.50.09U, but the same problems occurred also with the stock versions.
Best regards;

I had simular problems and sent mine back to orange, they told me that some handsets have problems and that mine was not the first to get these problems. since the replacement no problems at all. hope this helps.
Meanwhile, I had two consecutive unexpected nightly reboots...
So I'm actually considering sending the device back. :-(
have you guys tried to reset the device?
Hello,
I have a random/erratic problem with my SGSII reporting that the baseband is unknown and no IMEI being present.
It happens randomly through the night, or if the phone reboots itself, the signal icon changes to a circle with a line through it, and no network connectivity works (except for WiFi).
I've backed my \EFS up previously and restored that with no luck, re flashed my modem with no luck.
Usually the fix is to reboot the phone a few more times and eventually it comes back on.
I've got an app called 'network' which gives me various stats on the connectivity type etc (from my nexus one days) under 'Set preferred network type: I have an extra entry called 'Unknown' which gets selected by the phone, and changing this to one of the GSM variants doesn't have any effect.
Like I said, it's random and not much of a show stopper right now since I'm thinking it's a software problem. I don't want to RMA my handset just yet.
I have seen some other threads where people seem to have this permanently and there are no resolutions provided in the threads.
Has anyone else experienced this?
Kind Regards,
Chris.
I m relieved to know someone else also has this problem. Last Sunday my handset just hanged on lockscreen, so I pulled out battery, reinserted it and sim stopped detecting, so I tried couple of restarts, factory resets still nothing. So flashed firmware a couple of times still nothing. So when I checked if firmware was flashed correctly, the baseband was showing unknown and IMEI was completely blank. Handset is still in warranty so I don't want to take any chances, I am sending it in on Monday. Will keep you posted on what happens. Let me know if ur problem is solved.
Phone started regularly reporting that the SIM wasn't inserted so a quick phone call to O2 and a courier is coming to pick the handset up tomorrow.
Still under warranty so they should be able to fix/replace it.
Pain in the backside though to back up everything and then reinstalling it again when it comes back (either repaired, or a new/replacement one)
Right,
I got it back.
Apparently they identified it as a faulty SIM card slot. I was sceptical of this at first, but I persevered with it.
Surely enough, 1 day into using it, the same happened.
Back to the repair centre with photographic evidence of the problem.
Same happened to me a few night ago, removing the sim and re-inserting it fixed the problem for me.
I haven't seen it again yet.
I was on the stock firmware and insecure kernel.
me too... never been update or using any clockmod firmware..it just suddenly happen... any other way to fix this...
I'm also having the same problem for days now. My phone is full stock, never rooted it, never installed and unsecure kernel.
It randomly loses IMEI, Baseband and GSM signal. Sometimes it comes back after rebooting phone, but sometimes it seems to be permanent.
About a week ago when I tried to use my phone it said no SIM card inserted. The SIM was in and unlocked as I had used the phone about an hour before without any problem. I rebooted the phone but still it said no SIM so I powered off, removed the SIM, cleaned it and tried again. Well after about an hour of messing around the phone started working normally again. I didn't do anything more about it and wrote it off as a glitch.
I woke up this morning looked at my phone at it was asking for my PUK unlock code. It seems as though the phone must have rebooted overnight or something and now it's asking for a PUK. Why would it do that? I can't unlock it as my copy of the PUK code has worn so I cannot see all the numbers any more so I'll have to go to my network provider.
My question what could be wrong with the phone that is starting to not recognise the SIM? The issue last week must have been a prelude to this and it's pointing to something failing in the hardware. Any ideas what can be causing this?
Did you flash any ROMs or Kernels? Because that may be the problem usually.

Please give more informationhone Model,Kernel,ROM...
Sorry should have given more information about the phone.
It's a UK GT-I9100 model running stock 2.3.4. I haven't flashed any Roms since updating to 2.3.4 over a year ago. I've been holding out for the UK Jellybean which I've just downloaded ready to go once I sort out this problem.
I think I read somewhere that moisture on the usb port may cause this problem but I can't find that any more and I'm not sure if I'm remembering it correctly either. Although, my phone has never been submerged or even got wet in the rain so I don't think it's moisture.
I just tried putting another SIM into the phone and it works fine. As soon as I put my SIM back in it asks for the PUK. I guess I'll need to go speak to my network provider. Would still like to know why I started having these SIM problems.

Dude,I think your SIM card got blocked.Go to your carrer provider,and ask them to unblock it
I went to my network provider and got the PUK and unlocked the SIM. I asked if they had blocked it or if had been blocked and they said no. They said I must have entered the SIM pin incorrectly which isn't the case as the phone was one and the SIM unlocked before I went to sleep. I put it into flight mode and the next morning when I looked at the phone it was asking for the PUK. That with the previous issue where the SIM wasn't being recognised points to something not quite right either with the hardware or software.
I'm going to be updating to 4.2.1 no that the UK version is available and see if the problems still continue.
Was just casually using my Amaze today with the official CM10 I've always had on it, and all of a sudden in the middle of a call the call dropped and the phone restarted. I thought it was just a random reboot as they are nightly builds. After it restarted there all of a sudden was no signal. I was a bit confused as just a minute ago before I started the call I was getting full bars on 4G. I tried rebooting multiple times, changing SIM's (the phone is unlocked), even trying different ROMs. All of them had the same problem. No cellular signal. I tried the *#*#4636#*#* to set the network to WCDMA, however it was always stuck on "unknown". No matter what I changed it too it would always reset back to unknown. Then I finally thought I had to resort to an RUU.
After reflashing the Mobilicity RUU (stock one that came with the phone) on gingerbread, the signal FINALLY worked! I was so relieved and went to download the ICS OTA update so I can start flashing ROM's again. Then all of a sudden in the middle of the update the phone restarted, and when it booted back up again, no signal again. I then went to check for software updates again and just wanted to try downloading it over WiFi. I accidentally clicked the phone info screen instead of software updates and I noticed that the IMEI, IMEI SV, Phone Number and IMSI were all "Unknown". This was really odd. *#06* also brought up an empty IMEI box. Then I clicked software update and it said there were no updates available. What? It just worked a while ago before the signal broke again!
I then pulled the SIM out to run the phone WiFi only until I could figure this out and I noticed that it wouldn't say "No SIM" with no SIM card inserted like it normally would, but would continue to say "No Service" as if there was a SIM but there was just no reception in the area.
I've been trying all day to flash multiple RUU's and the only one that fixes the problem is reflashing factory Mobilicity GB RUU. Then signal works again, however after any restart signal will break again and won't work anymore until another RUU reflash. Is there anything I can do? This is the only phone I have to use and it's driving me nuts! Any help would be greatly appreciated!
Please acknowledge that I am not asking for a way to obtain or change my IMEI, as I know that is not allowed. I am asking for a way to fix the No Service issue I've been having.

Now another thing has arises. I try to use it as an iPod/Media player now and just use it connected to WiFi. However the battery dies after about 5 hours of just standby, untouched. It's all because of "Cell Standby" using up battery. It uses up 4 and a half hours of battery and 100% of the time it's without signal. However, even if airplane mode is turned on to disable the cellular radio, it doesn't make any difference to Cell Standby.

I have had this issue twice ... first time it happened maybe 9 months ago and stayed like that for 3 weeks with me constantly flashing and wiping and s-offing no no avail ... one day I pulled out my sim and memory card and when I switched on the device it says "no simcard" it never said that b4 so I switched it off and put back in the sim card and memory card and poof it was suddenly working again...
The first time I recalled not installing anything for months before that event other than one app..... "What's App" I installed what's app and used it fine for 2 weeks and the phone just dropped in the middle of a call and never regained signal.... so I said since that was the only app that I had installed its probably the culprit, so I will never use it again since the phone started working again.
Sadly 7 months later a girl i was talking to kept insisting that I install whats app because she wants to chat more... Against my better judgement I went ahead and did it and it worked for 2 weeks and one morning .... poof "no service" no imei .... and the culprit .....? WHATS APP!!! sadly I have been in this state for a month now with no sign of it fixing itself again... thank you whatsapp... let me know if whatsapp was installed prior to your loss of imei

Actually my Amaze started working again as well! One day around two weeks back all of a sudden it decided to start working again, but I just left it there as I had already bought an Xperia ion to replace it. One day my friend asked if he could borrow it for a week or so, I let him and when I popped his sim in it worked, checked imei, apns, everything was good. However later that day during the lunch hour he took it out and told me there was no signal. First thing I did obviously was check the imei and of course, it had disappeared again. Nothing in window when typing #*06# and in settings imei would say "unknown"
I never used whatsapp before and he doesn't use whatsapp either, it's never been downloaded on the phone so it's not the problem for me. If I reflash GB RUU it will work again and imei will come back BUT only until you reboot, after reboot it will lose imei again. Honestly it seems to have a mind of it's own when it comes to working or not.
I'm Having the same issue right now anyone have any ideas?

Having the same problem too!
Tried removing the sd and sim, rebooting without, reinstalling them, rebooting with, and no luck.
I'm planning to flash the Debloated Stock rom to try that, then I'll try the latest RUU, will report back... (could be a few days)
Debloated stock did not work. Latest ICS RUU did not work. Original, very first, RUU didn't appear to work until I did a restart (without the Sim inserted).
So it's working for now, although it's Gingerbread...

Really? I've tried literally every RUU available for Amaze and still nothing. Before, after flashing a gingerbread RUU the IMEI would work during the first use but would break after restarting. Now when I do any RUU, IMEI won't work under any condition.
Hello XDA Community,
Last Saturday my P20 Lite updated overnight. Sunday morning, when I checked the phone, the sim card picture with the (!) inside was on the top of the screen along with the message "No Service".
It had to be something related with the update (I guessed). Restarted the phone and all good. But only for a while. 30 minutes later the issue came back again. And then again, and then again. The phone works fine for a few minutes (good signal, 4G comms perfect, calling and texting too) and then it's just like someone has removed the sim card. If I'm connected to Wi-Fi, everything works except for the calling/texting.
Cleaned the slot, cleaned the sim card, network settings restored and still the same.
The solution to have network again is to turn the flight mode on and off all the time.
It seems to me that this is a software glitch rather than hardware.
Anyone having the same problem?
Thank you guys.
Same issue
Hi,
I've got the same issue here. Update just before I went on holiday and now I get a signal for a little while then it goes to no service. When it's ok you can check signal quality no problems. Once it stops it just keeps going back to main options screen, looks like a software bug to me.
Any one have any suggestions?
Update
Hi,
I've been in touch with my provider and they gave advised the usual:
Check coverage is ok - yes
Check some works in another phone - yes
Factory reset - not tried yet.
Anyone else have the same issue or an idea?
Exactly the same issue with mine since the update. Are Huawei actually going to fix this or are they just staying quiet?
What a piece of ****. After 3 days trying everything and resetting to factory still the same. No patch available. Terrible Huawei service say they're working on it.
I just went out and bought another phone. Mine is just 3 months old. Any ideas? Or is it scrap?
Support
I messaged Huawei in Twitter and they asked me to DM them but I can't for some reason. They wanted IMEI number so I'm no further on.
I have found that if you put the phone in aeroplane mode and then re-enable WiFi it is usable (except for calls).
Can anyone else message Huawei in Twitter to see what response they come back with.
Having the same problem here. Emailed and tweeted Huawei but no reply. Also experiencing slow charging, fast battery run-down, and general performance issues since the update. Phone is just 3 weeks old, bought in GB but now being used in Australia. SIM worked fine in my old British bought phone. Can't afford a new phone has anyone heard anything?
Location services
Hi,
I found that I was able to use all services if I disabled location services.
Got a popup about network time but the phone is at least usable - as a phone too!
I'm on holiday at the moment so will chase up Huawei when I get back and let you all know how I get on.
Did anyone ever get a solution to this having the same problem abroad currently
Mine resolved itself, but then come the NEXT update exactly the same thing has happened. It's been about 2 weeks now and the phone is practically unusable with fast battery run-down and slow charging too. Huawei customer service is terrible and don't give me any solution beyond a factory reset which I've tried to no avail. I'm also overseas too having purchased the phone in the UK and am now using it in Australia.
Did you guys get the phones working again?
