I'm running MIUI on my UK Desire Z, on a T-Mobile pay monthly contract. The phone frequently goes into Emergency Calls Only mode for no apparent reason, then goes back to normal in a couple of minutes.
Has anyone else had this problem?

I have not had this problem, but I believe that once the phone goes into Emergency Mode, it should require a battery pull and/or a reboot to return to a normal state of operation. Perhaps try a battery pull? This is supposed to be a security feature so that if something happens your location can be tracked... or so I've heard.

That's the strange thing - it rectifies itself after a minute or two WITHOUT requiring a battery pull or any other kind of intervention. I'm just wondering what puts it into this state in the first place???

I think it may also be a sign of a bad SIM card. Actually yeah, I don't know why I didn't think of that first. If it were me I'd try a replacement card and see if that resolves it.

Trying a "replacement card" sounds easier said than done. Do phone companies issue replacement SIMs without the need to port the number from the original SIM?

Yes. SIMs go bad from time to time, and they can easily issue you a new one (keeping your existing number). Not sure about UK, but in the US, the easiest way is just walk into your carrier's store, and they can fix you up. Some carrier ware technically supposed to charge you $10-20 for a new SIM, but they will often overlook it. Really, the things cost close to nothing. And the SIM simply enables you to use their service, and for them to make money off of you. So why not give you one for free?

The phone moves to 'emergency calls only' intermittently when switching networks or turning in/out of airplane mode, etc.. if its staying in that state, your phone is either having trouble keeping network connection, or isn't properly registering on the network. Id check to make sure your APN's are correct and if they are then id go about replacing the SIM possibly.

Have the same problem, but need to reboot my phone to work(( Have no idea except bad SIM-card. But it's registered to the person I've never known, so I can't change it((
I'm having the same problem in uk on orange (signal sharing with tmo).
As I wright this I have 1 bar but says SOS. Bam.... 2 bars orange. It seems to be when it would normally switch to tmo. Been like it for 48 hrs now.
I'm going to give it another day or 2 then investigate further if needed. Could be they are doing network maintenance.
Sent from my HTC Vision using xda premium
it might due to soft bugs or sim or singal issue. Need more info for investigation.
SYMPTOM: can't see any mobile networks
BACKGROUND: I've been using htc one x for a month now. Initially on three, but their signal was unusable at home, so sim-unlocked and switched a couple of weeks ago to giffgaff ( a virtual network on top of the UK o2 network).
All has been fine, until today. I sent a few texts & calls in the morning, and mobile data was working. Since then, I can't see any mobile network.
wifi is fine.
Search Networks pops up "Error while searching for networks" and finds none.
No software changes of any sort since last successful call. No changes at all today, at least until I tried to diagnose the problem.
Running stock rom, with the WW update of a couple of weeks ago (1.28.771.9.CL56522 release-keys) -- neither S-OFF nor unlocked bootloader.
Nothing obvious to me in the normal or radio logcat logs.
The only thing I did after the last successful call was to run sensorly to try and map a trip. I've used this before without any problems. It got no connection but I thought nothing of that. I've since uninstalled it just in case it could somehow be interfering with the radio.
THINGS I'VE TRIED:
No, the airplane mode isn't on, and mobile is. I've toggled airplane from settings and power switch, many times
recreated the APN
checked other phones - yes there are a number of networks visible
tried the original o2 sim - same problem
safe mode
cold boot
reboot, reboot, reboot
obviously I haven't pulled the battery...
turned off wifi, in case it was somehow interfering
HTC diagnostic tool
factory reset
confirmed imei is not blocked
Any ideas? Bearing in mind that I'm looking for something which can happen spontaneously.
Interestingly, while writing this I've just noticed that Baseband version shows as Unknown. That worries me - is it possible that my radio partition has spontaneously corrupted itself?
I did speak to 02 support - they said to take it into a shop for warranty repair. I don't want to try a custom ROM just yet -- not when I might have to use the warranty. But is there any way to force it to reinstall the stock rom (preferably not involving windows)?
I have the same problem as well and flashing custom roms did not solve it for me. But for me even the IMEI number is shown as UNKNOWN...I haven't done anything special to get this issue, one day when I woke up the phone could not connect to any network.
I have tried a lot of different methods but with no success. I don't think we can do anything about the baseband without S-OFF.
If a hard reset fails, then it's time to think about returning the unit. Either get a refund or get it replaced.
This may be irrelevant; but I've had this happen to me on my GNexus. I solved it by going back to stock and it just fixed itself overnight.....
my HTC One X did the same after about 2 weeks. Gave it back to supplier, waiting my replacement.
Even tested with a different SIM card, did a hard reset. Problem stayed the same.
Im curious did any of you find a resolution to this? it happened to me a while ago but yet to fing a solution. HTC refuse to fix under warranty because it is unlocked.. i am currently waiting for the next official update to see if that fixes anything but the way things are looking that could be a while..

It sounds like a fault, probably the radio chip has just stopped working, no software is going to repair that. If it was a software problem, there would be hundreds or thousands of people all having the same issue.

Hi, I have a ATT Note 2 and I keep getting the error "Phone Not Allowed MM#6" every time I turn it on. I can press the OK button and get to the home screen and use the phone normally except that it cannot send or receive texts or calls (emergency only). I am on the Solavei network and has been working fine for a few months, but the other day it just stopped one morning after I woke up.
I bought it from a store and he has assured me it wasn't stolen or anything like that. And the Solavei customer service could not get it working after several resets and whatnot. They sent me a new sim card which I have not received yet, but I am not very hopeful about that working... My WiFi works and I actually get signal bars but again, no 4G, no calls, no texts...
Is there anything I can do in the settings or anything? My phone does not have any custom roms or anything like that, just the regular ATT/Samsung Android 4.1.2. The only thing I changed on it was the option to enable the T-Mobile bands (Youtube: How to Enable T-Mobile 3G/4G AWS Bands on AT&T Galaxy Note 2 SGH-i317!). But I also tried without those bands and that didn't work either...
Please help, thanks in advance!
Try a complete factory reset with Odin. But that error sounds to me like someone reported the IMEI as stolen

Go into your local store with the original recipt. They should be able to either tell you who reported it or give you a refund

there can be two reasons.. one is when you tried to change the bands on your phone there are more possibilities your IMEI on the phone would have corrupted and that is reason you might be getting that message, and second reason can be some one reported the phone stolen and it is blocked from the service provider end..
to validate that check your phone IMEI by dialing *#06# if that shows your valid IMEI then your phone must have got blocked by the service provider or incase if the IMEI shows some thing like null or 00/0 then the phone IMEI is corrupted, I can help your fixing your phone IMEI if it corrupted.. let me know if you still having this problem
Thanks everyone. I called up ATT and they confirmed that the phone was reported stolen. So I took it back to the store I got it from and he said that sometimes this happens so the company can get the insurance... Regardless, he reset and rooted my phone and it works again. My IMEI number shows up as well. Now the only thing is that I am not able to get all of the T-mobile bands back. Does anyone know about this?

AT&T
Hello my name is Stanley, I recently bought a Galaxy Note 2, I'm from the Dominican Republic so I'm using Claro Dominicana, which uses the same baseband as AT&T, basically instead of the signal bar, I get a circle with a straight line on it, I don't have data, I can't make calls, I can't send sms, when I try to call I get no network access message, I believe it does recognize sim because I don't get any type of error when my cellphone boots up, when I bought this cellphone it wasn't rooted, so I decided to root it and flash a rom, I'm having same issues.
Can you guys help me out please? I already have my APN information but it's not helping, I've tried flashing roms and it's not helping, I really don't know what to do, when I first bought it, I tried my sim out and it did have internet, I decided to do a factory reset through settings menu and after that I haven't been able to get any type of signal, I would deeply appreciate your help guys, I'm getting kind of desperate here.
No signal bars means no modem or a sim card for a dead account. Did you pay for any airtime?

I did try it, I'm pretty sure is unlocked because it was just working before factory reset, I guess I can try to do it again, but I'm pretty sure is unlocked.
I tried several roms and modems and nothing worked, the last thing I did was going back to stock through Odin, but I still get same circle with the line on it, a stop sign, right now I'm on 4.1.1 stock..

i don't know if this might be an issues or not, but check your IMEI. T-Mobile webpage has a method to confirm if it been blocked or not.
http://www.t-mobile.com
As of August 8th of 2013, they've re-designed their webpage.
http://www.t-mobile.com/bring-your-own-phone.html
following that link, scroll down until you see this: "Don’t see your device?" and under that, a search box. click on the link below that search box. it'll bring up a screen within the webpage. input the IMEI from your phone (*#06#) and avoid adding "/ ##" as those aren't part of the IMEI. If it report as stolen, chances are, they probably blocked it. If not, then maybe your provider doesn't support the phone itself. you might have to call customer service from your area.

I couldn't find information about my imei using that webpage, it wasn't able to locate it, I used this webpage which said is clean http://swappa.com/esn I don't know if that page is good, but it says it's clean and ready for activation.
Try a friends sim card to rule that out
If the phone worked on your network before you rooted and flashed the new rom, then I imagine you must have flashed an incompatible modem. If you flashed stock back via Odin and that didn't fix it, I'm scratching my head. Try stock again. Then remove and insert the sim or toggle airplane mode. If it worked before, stock should fix it.

Hi..
I have a Zenfone 5Z, bought on GearBest, so yesterday it updated to the latest WW version o it's on. After updating it lost the Network Signal, even after a several restarts. I've downgraded it to WW__ZS620KL_80.10.8.54_MP_user_20180517175955 , but still no network signal.
I've tested my simcard in other phones, other simcards in my phone, but still nothing. When i try manual network seach, it gives an error, and when i select automatic network, it says that is already registered to network, and when i try to make a call, it says me to turn off airplane mode to make a call. Also when i remove and reinsert the simcard it recognizes it a makeme chose betwen sim 1 and 2.
I've attached few screenshots too.
Pleaase help me guys!
P.S. i gave this phone to my wife on her birthday, now, she is mad with me!
HI,
I had this same issue, later i checked up with service center, they told charging pcb(which contains antenna lines) was water damaged.
Then got replaced the part and started working again.

Nop, i had to send the phone to Asus authorized service center, they changed the SUB PBA...
I works for exact 30 days and, after a restart becouse the system crashed, it has no network again!
so i sent it to serce center again today...
As I don't see a reply stating how it got resolved, I will post my experience of this issue. Firstly, this issue is fairly common with Huawei 5Z. The reason given by local service team here is at times if the phone experiences some jerk the contact from antenna to motherboard breaks. At times it could still remain connected in which cases person may get signal some time and get airplane mode at others, in many cases airplane mode is ON permanently. Apparently they have some kind of a glue with which they can attach the antenna permanently. Once I got it done, the problem has not resurfaced.
P.S. this problem has got nothing to do with software, so restart, factory reset etc. will not work, nor does it happen with software upgrades. It is purely mechanical in nature and does not need even require a drop. but the solution is quite simple provided the service centre team knows. In case they don't just ask them to stick the antenna connector with a proper glue and it should be sorted.
What am I supposed to do with my set. I imported it to my country and can't find a service center anywhere in my country. Apparently I can't find any solution online so I am out of luck. If there is anyway I can fix it, or anyone could share what should be replaced will be immensely helpful.
Need your help guys.

Based upon above comment if the root cause is same as described i.e. connection b/w motherboard and antenna bands is broken then you can watch teardown video on YouTube for 5z by wit rigs. It shows how you can disassemble each part of the device for repair.
Apparently you will need to have some expertise and tools available to perform the task yourself. Better work with some local mobile repair workshop and explain them by showing video and above comment.
i am currently using 5z and i can says its due to updates especially from oreo to pie ( yes this problem is originated from that update). Its a software problem and they cannot solve the bug till now. There are still lots of 5Z with this issue pop up every week. The solution is to send to service centre to replace the motherboard and pray it wont happened again. This is my second time sending my phone there for the same issue. The antenna or motherboard dont simply fry or disconnect after an updates thats for sure.
Randomly changing different sim cards in the sim slots along with fiddling with the mobile data setting that comes when you insert the sim card tray worked for me, it worked for someone in zenfone forum also. Give a try and let everyone know..
Same here, after update signal lost... damn ASUS
My network signal stopped out of the blue and not after an update.
I tried changing sim cards in a lot of different combinations, but nothing worked, but the phone always found the sim cards.
I disassembled the phone, removed the antenna cable and attached it again and now the network signal is back again.
I had same problem. After the latest update, Everything working fine untill one day i restarted my mobile. Damn.. After reboot, the signal disappeared and can see 'x' at signal bar. I have rebooted many times but of no luck. Then i removed the sim tray , swapped the sims and then the signal starts showing. Initially after the update, one time I faced same issue but that got cleared after I disabled and enabled the sim in "Sim Card Information". The only issue i a, facing is the signal drops for every few minutes or hours and comes back automatically. That's what making me to replace my phone other than ASUS. Does anybody have a solution for this issue?
Update :
My phone had a sudden reboot and since then there is no network. Showing no service even if i swapped sims and re inserted. frustrated with ASUS

No. In my case/In most of the cases, its not the harware issue. initially i thought the same. But later found that only after updating to the latest update i faced network loss issue. sim not used to detect even after taking the sim tray out, shuffling with sims. I downgraded the firmware to previous version and then immediately i could see full network signal. So the issue is only with the latest, not with the hardware. Just give a try and confirm..
The same i have mentioned in that post also. Just give a try and update. Definitely that will work

The only solution is to walk to the nearest service center and make the antenna fixed. I have given my phone to the authorised service center and they resolved the issue by applying glue to antenna (they told same). They charged for the diagnosis as well as for glue. They guaranteed that the issue wont repeat. But i hated the service by ASUS and planning to go for samsung or Oneplus.. My suggestion is go to service center to get it fixed
For all of you still facing the issue, the solution is extremely simple. And yes it is purely mechanical in nature just like someone mentioned too. I just wrote a post regarding this. Check it out.
