After Android 10 update no phone calls possible - Nokia 4.2 Questions & Answers

Hi,
I got the update to android 10 yesterday and installed it. My provider is Vodafone DE.
After update, I'm not able to make any calls (or receive ones) anymore.
I already figured out, that this problems does not exists when I'm disable 4G and switch to 3G only.
I also tried out another carrier (Telekom DE), there the problem does not exists (VOLTE is activated).
I cleaned the cache of phone app and google play services. I also already resettet the network several times.
Any more suggestions what could be problem / how to make phone calls working with 4G enabled?

Hi,
I have exactly the same problem, after update to ANdroid 10 no phone calls with 2G or 4G via vodafone in Germany, SMS and (apparently most of the time?) mobile data works in all 2G/3G/4G; another SIM card from the german provider Telefonica/O2 (under the lable BLAU) works fine; the Vodafone SIM also works in my old mobile.
I noticed something else: in the SIM-card settings (where e.g. the color can be chosen for SIM 1 or 2), while under "Mobilfunkanbieter" for the BLAU-SIM card, there appears O2 -.de, vor the vodafone card, it sais "unbekannt"
Did you already find a solution?
I ordered a new Vodafone SIM, same problem; even resetting the whole device to factory mode didn´t help.
Probalb you are aware of a similar (yet apparently sifferent) problem with Nokia 8.1 in automn (I´m not supposed to post URLs here, you may prbably find it yourself in the vodafone forum, the thread there is in German)?

[Q] Emergency calls only

Hello friends, how are you?
My name is Renato and I'm from Brazil. Some weeks ago I bought a Galaxy Note N7000 unlocked by TIM operator. It comes with
android 4.0.3 and I never updated the android or did any hacks.
Well, until yesterday, everything was fine. But yesterday, when the phone starts, it find the operator's signal but after some seconds it enter on the
emergency calls only status. Also, even it's blocked for emergency calls only, I can use the internet 3g without a problem! Very very strange...
I already checked my sim card and It works on my older nokia without a problem. Also, I put another sim from another operator (Oi operator) and it works without a problem too. Also I check my sim status at my operator and it´s unblocked too. I did a factory reset too and nothing changes...
Looks like my galaxy note cannot work with TIM sims anymore?
Please if somebody have an idea about this error, please let me know.

Note 5 (SM-N9208) Call related issues

Hello,
I have SM-N9208 with T-Mobile(personal) and ATT(work) sims (build number NRD90M.N9208ZTS3CQK1 just updated) and I have been having call issues when I try to use T-Mobile sim.
When try to make a call using T-Mobile sim, most of the time either me or the other party cannot hear each other when the call gets connected. Some times call does not even go through and some times it connects just fine!
I had replaced the T-Mobile sim, tried with ATT sim out, tried with headphones and bluetooth but issue/s remains. I just updated the phone with above build but still no luck! I did not root this or flashed with any rom (factory or otherwise) thus far. All the updates were always done through wifi. A few days ago I had also reset this to factory default and erased everything and I installed everything from play store with out restoring from backup. Nope that did not solve the issue either! I also notice now that when call is ongoing with on T-Mobile sim and if data is set to T-Mobile, I see E instead of 4G! By the way I am in northern NJ( not sure if T-Mobile is changing something on their end). Any call plased through ATT sim goes fine whether it is SIM1 slot or SIM2 slot.
Has anyone ever seen this and any help is greatly appreciated.
Also, can I load firmware from another country (say Philippines since I think my current firmware is Tiwan)?
Thanks,
Chuck

P9 lite no network but only with one operator

hello guys, sorry for my english (no mother language)
I have a huawei p9 lite unbranded vns-l31 c432.
turned off the device for the night and suddenly the nex morning turned on......and from that time it can''t connect to the mobile operator anymore.
I have tried various step, to understand if the problem is on the operator or on my device.
Tryed the scanning of the net manually, It can see all network around, meaning the radio function is working. But I can connect to the radio of my operator (and obviously of other carriers)
- tried the sim card on other phones and it is fully working
- tried another sim card of the same operator and it doesn't work on my phone
- tried other sim cards of others operators and they magically work
so I really don't understand this. The operator obviously tells me that if the sim card is working on other phones this means that it is fully working.
If other sim cards don't work on my phone maybe it could be the phone. but the phone is fully working with any sim card from others mobile operators.
my phone is unbranded and fully worked with any operators in these 2 years I have been owning it.
the operator tells me that they can block IMEI number for security reasons in very limited cases, but this is not my situations, since the phone wouldn't work with any operator.
I have tryed to roll back from android 7 to android 6 b161 release. and from b161 to the latest one, android 7. every step I have checked baseband version, wich is always changed. but in none of the firmware version the phone worked.
any idea?
thanks a lot

Mi 9 - Android Q Mobile Network isn't available

Hi,
I just bought a Mi 9 for my gf as Birthday gift and have a big problem with it.
We use her Simcard from her further phone, which works there without issues, but the Mi 9 just let her use Data on the simcard (internet). No calls or texts in-/ outbound are possible. It always shows that no mobile network is available.
I already readded all APNs (Internet, LTE, GPRS) and tried a couple different network settings (*#*#4636#*#*). I'm not sure why this issue appears and searched allover the internet. Seems like noone else have this problem.
Version is 11.0.2.0(QFAMIXM) with locked bootloader. Could it be that seller flashed something wrong, modem type or whatever? Carrier lock wouldn't let us use the actual sim right? My own sim as well just work with data so it need to be an issue with the phone.
Thanks in advance
Chris
Noone have any idea what the issue could be?
This seems like an operator related issue and probably has nothing to do with the Mi9. Try operator related forums for more help. The only thing that comes to mind is to get a new sim from the operator.

Question:
Does mi9 recognize the SIM Card? Does mi9 ASK for your SIM Card PIN? Or does mi9 say 'no SIM Card installed'?
Hi,
Sim is recognized and contacts shown. Sim pin is deactivated so the Phone don't ask.
Mobile Network is shown and active and data/ internet works. Its just the GPRS funtions (Text, Calls) which don't work. When I try to call I get the "Mobile Network isn't available" message and texts don't sent.
Thanks

The Sim works fine in another phone and my sim which works as well, shows the same errors in the Mi 9. So it must be an phone issue.

What operator do you use? What operators are the respective cards you have tried in the Mi9? Did you buy the phone from a private person and not new in a sealed package? In this case contact the seller.

Do you have 2 simcards installed?
You also might try to reset the modems, howto you can find when searching the forum
Just 1 sim installed. 2nd slot shows the same issues. Will check the forum for modem reset thanks.
Hi,
Weirdly the phone seem to have a Carrier Lock. My gf uses SMART Prepaid here on the Philippines and as said just mobile data was working. Yesterday she switched the SIM for testing to Globe and with this SIM everything works. 4G is available and calls/ texts work as they should.
I'm still confused about this. If the Phone would be carrier locked, should another Carrier SIM not be functional at all? I don't get why Data connections are working then.
For now the solution is to get another SIM. Probably let it unlock in a store.
Regards
Chris

Samsung S20 Not Registered on Network (Please help)

Hi Everyone
I purchased a second hand s20 6 months ago and i am no longer getting any network carrier coverage.
I took my phone to local mobile repair shop and they identified that my base software was South Korean for some reason so they factory reinstalled Android 12 with UK Software. (This still does not work and they are stuck trying to solve the problem)
I'm fairly certain that this issue started when i upgraded from Android 11 to 12.
Please can anyone suggest a possible solution for my phone problem?
Things i have done so far:
1.) Factory reset phone several times including separate network resets.
2.) Tested my new replacement Virgin sim card in 2 other phones (This works)
3.) Tried several working sim cards in my s20 phone (None worked)
4.) Confirmed my phone is not barred or locked.
5.) Checked that i can see other Mobile network operators (Does not connect when i select my provider)
6.) Tested in other cities to confirm it's not a signal coverage issue.
7.) And finally, my phone has the latest Android 12 updates inc local app updates
Thank you
Just to add a further update, i have managed to get my phone working intermittently through WIFI but i still have an issue when outside my home.

Your phone can be in the blacklist as some unpaid fees in the contract of origin provider you purchased this phone. I had exactly same problems and after pay all over due bills phone went into normal.
My S20 Ultra LTE keeps detecting a ghost SIM in the second SIM slot and is making my phone lost signal. Is there a way I can convert it from dual SIM to single SIM?
