P20 Lite Losing Sim Card (Service) after last update ANE-LX1 8.0.0.147(C782) - Huawei P20 Lite Questions & Answers

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?

[Q] SGS2 3G Hanging

Hi,
I've had my SGS2 now for around 2 months and thought it maybe be a firmware bug, but have recently upgraded to the latest via Kies which is KE4 and still notice from time to time that the my 3G just wont work.
If I try and access anything via 3G for example webpages you just get page cannot be found, but strangely enough what I have noticed the is H symbol will have a Green UP arrow active but nothing ever happens. In order for me to fix it I have to disable 3G via apndriod and then turn it back on again, as soon as this is done the 3G works as normal. Does anyone know of a fix for this?
I'm on the O2 network if that helps but I think its more than likely a bug with the firmware/phone.
Cheers in advance.
Davey
I've noticed it happen once or twice... but I just hold the power button, and then de-activate and then re-activate the connection from the popup menu. Sometimes when it has hung it can take a fair while to kill it after de-activating as well. But its literally only happened 2 or 3 times in the whole time I've had it; I've had catastrophic battery drainage more often which is a lot more annoying.
I've had the same issues on my phone aswell. I just got mine back from the repair shop and the problem still remains. The guys on the repairshop said it worked fine when they had it, but now its the same again. I dont know if it is my network operator who has problems with my phone staying online or what it is. But its damn annoying, I to have to disable / re-enable the 3G connection for it to start to work again.
I've yet to find a fix for this.. I'm on a network called OneCall, in Norway.
Any tips would be great
I had the same problem when I disabled fast dormancy.
Hello. Since about a week ago, I have this problem PERSISTENTLY. My phone is 3 months' old, I bought it new and unbranded from a store in town, and never rooted it. Only thing I did was upgrading the firmware through kies to the latest version available in my contry (KE7 if I'm not wrong). I have adroid version 2.3.3.
Well, I have found no solution to this problem that is absolutely unbearable.
I shall get rid of this phone as soon as I can because I am really annoyed by discovering problems after problems. I never had any iPhone, but I will try buying the iPhone 5 when it comes out. Hopefully it will work better. After all, it can't be so difficult to make a phone better than this one!
By the way:
I have 2 contracts with vodafone, one on this phone and.the other on a Nokia n95 8GB. Tried swapping the sim cards. Reault is that after the swap on the nokia there still are no problems whereas the SGS2 is still hanging on 3G and H.
So it isn't a problem of the operator, neither it is a problem of sim cards (also because they are different, one is 32k and the other is newer, and 128k).
Now, before throwing this absolute crap of a phone out of the window, I'd like to try a factory reset. But the question is: will I have to reinstall feom scatch every single app, after the reset? Is there a way to back up allbthe installed apps and easily reinstall them, without rooting the phone? I absolutely don't want to root the phone because I'm pretty sure I will end up selling it and so I don't want to loose the warranty.

Factory reset will mean you lost all data, everything on the phone that you dont backup.
But that might not fix it, your best bet is to try a newer modem, as its more a modem issue not a rom issue.
Thank you, veyka.
I just seem to habe found the solution! I disabled fast dormancy by dialing *#9900# (there's a hidden menu).
So far it's working great! It appears that my mobile network is not optimised for that protocol, therefore it must be disabled im.order to get proper internet connection.
So... anybody with this problem, try dialing *#9900# and tapping on "Disable fast dormancy" it is a fully reversible action (just in ca se...). Im fact, it cam be re-enabled at any time from the same hidde menu.
POST NOTE: No. This doesn't work. I spoke too soon...

This problem has been around for a while and I read somewhere that Samsung said they were working on a fix for it. I have had the problem from day 1 and it still does occur with Fast Dormancy disabled. I don't know if some of the newer Firmwares have fixed this or not. I am running official UK KF3 Firmware.
In fact, the fast dormancy trick worked only foe a short time. Now I'm back on wifi. What a disaster of a phone.
I talked to my network operator last night. They told me to go to settings->wireless and network->Mobile networks->Network operators and set it to manual, instead of automatic.
After this it seems like the problem wanished, but it might be just for now. Will test for a few days and come back to this!
Hey this is certainly a good suggestion! Maybe when signal is poor the phone starts searching for other networks and drops the connection. Good point indeed. I will make some trials as well.
Cheers

Keep losing data connection.

I have an unlocked unrooted S3 on Vodafone UK. This issue has been happening for the last few days whereby i have full 3G/H+ connection, but absolutely no data is working. No email, no websites loading, no whatsapp, nothing. The issue goes away as soon as I restart my phone, but then it comes back after a few hours.
Has anyone experienced this, and if so, how have you fixed it?
Go back to your network/phone provider .
Or flash different modem .
jje
I am having this issue too. I may be wrong, but i realise this happens if i turn off my Wifi, the 3G will not want to connect to the 3G network.. Anyone else having such problem?
By the way mine is International version (Location: Singapore)
I'm having a similar problem where I have a good 3G/H/H+ connection but data seems to drop intermittently across all applications - I get the same sort of error message in browsers/facebook/twitter that you receive when you have no signal.
Anyone have anything similar and know of any fix?
I am not having such issue so far. I been updating my SGS3 using over-the-air update. I guess the MODEM has been updated as well.
Go to market and download "fast dormancy"(by gorkhanmoral) then disable it and reboot.
Check if your speed has improved,if it got worse then enable it again.
U need ROOT to use this tool.
I it didn't help, then flash a different modem
This is good modem
Cwm flashable

have you got any battery saving app like juice defender installed in your phone?
Is mobile data working at all? or is it constantly "uploading" but never "downloading" (up arrow lights but not down).
If what I just described is your issue then this is a network issue relating to android in general.
Basically your phone will be connected to two radio towers and gets confused as to which one it should use, rebooting or flight mode may help force it onto one tower or you may have to speak to your carriers "high network technical team" or whatever they are called for you to get them to force it onto one tower.
I had this issue on the HTC hero (a long time ago now) and it took 9 months for Orange UK to work out what was going on.

Congrats. Orange Luxembourg (my gf's network provider) still hasn't got a clue.. But they seem rather clueless about everything except writing invoices.
Flashing an Asian modem on her S2 made the issue far less prominent since they seem not to get confused by antenna ping-pong. (Tango Luxembourg, my carrier, has this issue too in the main city)

[Q] 3G not working

Hi there.
I have Lumia 920 Black on EE in UK.
Last month when Amber (french one) got leaked, I installed it and tried straight away.
It wasn't big difference to me in fact it had a bug where if I create an all day calendar entry using google account (not tried with Live account),
it will save the even entry as day before?
It bugged me so much so I decided I will install EURO Dev version.
So I did and everything seem to work fine untill I go outside my house.
I kept on getting no signals. And when I had signal it was constantly on EDGE. Never on 3G.
I did reflash and restart and all it doesn't seem to help. When I restart the phone I get 3G briefly for seconds until it loses service totally then come back with full EDGE signal.
I have found a old firmware RM821_1232.2109.1242.1010_RETAIL_eu_euro1_342_10_97021 and flashed it. And did update through OTA.
Still no 3G. I called EE today for help. They told me it could be the sim.
So I tried on my old iPhone 4 and its all good. I get full 3G.
Anyone know what may be the problem? And if EE offers a repair, will they found out that I've playing with flashing the device and tell me its not covered by the warranty?
Thanks you all!

I know the issue exist on the ATT Dev Rom, you just have to go into the Access Point app in the settings and pick the correct APN, (the flash defaults it to the wrong one. ) but I don't know if that's the case for the EE version. I suppose is possible, it can, and is suppose to load, the APN from the Sim, so if it worked with the iphone sim then check those settings.
Thanks for you reply. Did what you said but it did not help at all. It's not like my data isn't working. It's just on EDGE all the time. Sometimes I don't even get calls through and later get message from EE saying I had a miss call. Called Orange (runs on EE) about it and they said maybe its my sim. So tried it on my iPhone and I get 3G straight away. Need to ring them again. But their call waiting time is ridiculous. Called them yesterday and call queue was 2 hours!!

Internet settings for Life Mobile (EE) in UK

Hello there,
I have been using Tesco Mobile with my Redmi Note 2 for a couple of months now and have had no problem. I decided to switch networks to a VPN called Life Mobile. They use EE's network in the UK. Since putting in the sim card today I have not been able to connect to the mobile network. I am wondering if anyone else on this network with this phone could help? I have called Life Mobile's helpline and all they wanted to do was run me through EE's apn settings. I had already used their app and also searched elsewhere on the web to find a few different APN settings but none of them worked.
One thing I'm wondering about if whether or not the custom ROM/firmware (MUI 7 I believe) that the phone shipped with (bought online from China by the way) is having anything to do with the internet problems. I get the feeling the customer service for Life Mobile were fobbing me off when they said that maybe my phone just isn't compatible with their network. Phone calls and texts work fine by the way.
Does anything think flashing the phone to the standard android ROM that's available would have any affect on the internet settings. I'm no mobile expert, and with the phone not being on general sale in the UK yet as far as I know, I would appreciate your help to get this internet/mobile data settings issues sorted, as I do use my phone for work.
Thanks in advance for comments and help.
I definitely know that the ROM that came with my phone from Gearbest was the worst piece of software that I have ever used in my life... ever. Check your MIUI build number and see if it's something like 5.xx.xx or 7.xx.xx. If it's something more like 77.55.66, then you have a knock-off and it may be eating your battery, performance, and experience (the original ROM Gearbest flashed on my phone had so much bloatware that the antivirus warned me about one of the programs every ten minutes, and heated up significantly on the home screen). If you have an unofficial ROM, try flashing a developer weekly or stable.
Hi all.
Well, would you believe it, I have spent a large part of the day trying to figure this out and finally I've done it. I'm not quite sure how but I've done it. I'll explain briefly to help anyone else who may be facing the same problem. It seems that changing the network preference setting within the sim settings from LTE to 3G did the trick. Life Mobile does not support 4G as far as I'm aware. That's no problem for me as I'm perfectly happy using 3G when necessary. After doing that and fiddling with the network settings, eventually reverting back to the automatic selection of the network as EE and using the APN default settings as given by the sim when it first was entered into the phone, things suddenly start to kick into life and we had INTERNET!
Thanks for your help in resolving this, and happy New Year to everyone.
same problem
Hi mate,
I'm having the same issue now on life mobile, I've checked all the settings are right but still not picking up mobile data. Any suggestions? Constantly restarting it hoping something will be different but nothing so far.

Driving me crazy as well (on a Lenovo K3 Note). Still have the Tesco SIM in there. Was going to port the number on Monday, but might get them to take the damn thing back!
Tried all the suggestions above, but nothing working. Tried both SIM slots with and without the other SIM, but nothing. Grrrrr....

Well, they sent me a new SIM card and I had all the same problems until I switched on "data roaming" and it now works fine (it didn't do anything with the last SIM though, when I tried it in another phone, I had to have date roaming on in order to even get a regular signal- data still did not work). I have seen transient "R" occurring when the SIM was activated/deactivated so had suspected this as a problem.

No Service - All of a sudden - Have to do a SIM swap to get it working again

I have an Samsung S9 Plus that was an AT&T unit (I think) and I flashed it over to the global firmware so I could use it on Visible (Verizon). It has been working for months, but I have now had this problem happen twice. I get up on a Monday, and notice that my phone has no service. I think it says "No Network Connection" or something like that. The first time I tried many of the usual steps - switching airplane mode, resetting network, wiping the cache, long support chats with Visible. What finally got it working again was putting in another sim(from Red Pocket - AT&T). That made the phone go through a reboot to swap over to the new sim. Then I put the old Visible sim back in. The phone does another reboot, and now everything is working again.
Is there a way that I can get the phone to go through this process without swapping the sims? I would just like to know if there is a more efficient way of fixing this problem when it pops up.

Call your carrier and have them to a reprovision. I had this happen with T-mobile coming from Sprint.. They will have you turn off the phone, do something on their end, and after that it should work.
Just to update, I have switched over to ATT Prepaid. Since the change, I have not had the problem happen. I think it must have been an issue with Red Pocket. Either that or something that got fixed with an update. Just putting these data points out there for anyone else that is having issues like this.
