Cellular network not available - Huawei P30 Pro Questions & Answers

Good day everyone, I have p30 pro that I have been using for about 6 months, last week Monday, I discovered that I could not make calls or receive calls and text messages but my data network is working perfectly.
I have gone through all available diy solutions available online, even tried my Sim on another phone and same is working. But not on my phone.
I even factory reset my phone but the problem remains.
I have contacted my network provider but after I mentioned all what I did, they said is not from them.
I noticed a little solution, each time I put on the phone, I can make a call but once the call drops I can't make calls again.
Am thinking of downgrading the phone as I have 150 vog-l09 version. p30-pro/vog-l09/10-1-0-150.
But am still been skeptical maybe to send it to huawei for fixing.
I need help house.
Thanks

No service after dropped call

I have the Bell i9000M unlocked and used with Rogers SIM. Nothing else has been done to the phone besides installing apps (got the sd corruption on my first i9000m after using Odin and didn't want to go through that again).
Haven't had any problems for over two months but in the past week, I have dropped calls and could no longer make calls again until I restarted the phone. I have dropped calls before (there's always a couple of areas on my drive home where I drop calls using any phone) and have always recovered. But just this past week, I can no longer make or receive calls after a dropped call.
Sometimes the status bar shows the blue circle with a slash, but that changes to white bars. But even with bars I can't make or receive calls. When I check *#0011# it doesn't show that I'm attached to a network.
I can go to an area with strong signal and leave the phone for hours but still cannot make calls. The only solution for me is to restart the phone.
Anybody have this problem and know how to fix it? I've been searching for days but haven't seen a solution.
Thanks,

I had the exact same problem on my first 2 I9000M's. The only thing I ever found was to replace them. It was annoying as hell and made the phone impossible to use sending or receiving calls. the second one was JH2 with the 3BR fix. Texting was perfect as was the internet (3g).
I searched and searched as well. But I was talking with a bell guy about it and he said it may have to do with an IMEI issue they have a master ticket open 3449667. I know you are on rogers now, but hope that helps in some way.
Thanks, it is very frustrating and dangerous since I'm usually driving when this happens. Unfortunately my 60 days are up and I can't get a replacement. There must be a way to fix it since it was working before. Maybe a SIM issue? I'll keep searching and hoping and if nothing, then I'll do a reset before sending for repair.

Just to update, I got a new SIM card and I don't have the problem anymore.

[Q] Vivid Issue Receiving the Calls

Hi I am using the ATT HTC VIVID from Nov 2011.
I bought this phone last Nov 11, and I stated noticing my phone was not receiving any calls if I stay at home(jersey city). If anyone calls to my number it will not connect at the same time it will not sent to voicemail also. It will say "call couldn't be completed".
After 2 months fight with ATT, they tried
1. they did a factory reset on my phone - it didn't help
2. changed the sim card - it didn't help
3. finally they replaced a another HTC vivid
even that didn't help
finally they said there was issue in near to my home and they fixed it.
now i a started receiving calls but now the new issue is, if I call to my number it will not connect first time it will go to voicemail, and second time if i try then it will ring. (First time also my phone is idle) This is happening randomly and ATT is not helping on this situation. As per them I am not able to replicate when they were testing on my phone.
Because of this issue I am missing calls which is making me really frustrated. After three week of research I found this is happening in not only near to my home its happening at my work place (NYC) and if I go around also its happening.
Can someone please give some advice to fix the issue that would be really great
Is there anyone else in or around your home with AT&T service? If so, do they experience the same problem as you? Can you receive calls everywhere else besides home and work? Do text messages get through? How about internet service? MMS?
Thanks for your response
The issue is not around my place
The issue is, if any one calls first time it will go to voice mail, if they call again it will connect to my phone. This behavior is happening randomly.
It is happening in my work place(NYC) and also if i go some where in new jersey also. I can't tell when its happening and how. In a day it may happen one or two time. I can't check constantly on a day when and where.
Sometime i feel I am not getting call, if i try from land line it may work or it may go to voice mail, after the second try then it will be fine for that day.
this issue look little weird. but because of that I am missing calls.
forgot to mention, that time my internet will work fine, how I am sure is one time i was browsing and trying to call my phone from land line it didn't connect. as usual second time if i try it did connected
Also the signal bar in my home and my work place its full

"Call ended" right after dialing

First of all, I want to say that I found people with the same issue using Android everywhere and with a lot of different phones, so it's probably an Android bug rather then Moto X itself, but I wanted to leave my report.
I came from an S3, which suffered from the same problem when using Cyanogenmod. When using official Samsung ROM everything worked as it should. Now, I'm getting the same issue on my brand new Moto X.
When I try to call someone, sometimes it just doesn't call, after I press the dial button, it just hangs (without ringing) and finished the call with a "Cal ended" message. It happens randomly, and sometimes I can't call anybody for like 2/3 hours.
The simcard has been changed from the S3 (micro) to the Moto X (nano), so it's probably not it. Also, with the Samsung ROM it didn't happen.
I can still receive calls and messages, and the signal strength is fine most of the time. I just can't call.
Today I faced this problem and then I tried calling from my girlfriend smartphone (samsung ace IIx) at the same time, which is from the same carrier, calling to the same number, and it just worked fine. Mine still didn't work though.
Here is a thread on people on xda facing the same problem, but with a different phone: http://forum.xda-developers.com/showthread.php?t=2351227
Don't know what to do.
i've had the call not go through as you've described, but have never had a phone not let me place "any call" afterwards. i always chalked it up to poor performance (limited RAM, too many processes, etc). My DROID3 would do it and often times when it finally did make a call, there was zero sound and I would have to reboot the phone.

Hmm, it doesn't seems like poor performance. I ended up every task and it still happened.
However, I noticed that when I check the "2G ONLY" option it comes back to work. Maybe it's something with the HSPA/HSPA+ connection.
it could be completely carrier dependent then. my experience has been with vzw.
Moto X "Call Ended"
I have experienced this same problem in Houston on the T-Mobile network after switching over to Android. My T-Mobile rep told me they have had towers vandalized for copper which has impacted service for them, I believe he said it was about 15 towers and 10K a pop to get things corrected. What gets me is I was on a Bold 9900 and while I had signal problems in the affected areas of town I didn't not experience the "call ended" issue. I can also call other T-Mobile phones from those same areas but not land lines so to me this seems like a possible network routing issue which I have seen before between specific carriers.
If the problem does continue I may have to switch carriers. T-Mobiles service was previously outstanding in Houston but recently had not been great after the 4G LTE upgrades. I support multiple hospitals and need service to work correctly and will work with the T-Mobile Engineers to see if I can make headway on that front. I noticed another MotoX user reporting he only had the issue when flying in to Houston for work and that everything worked for him outside of Houston. His solution was to operate in 2G mode which for me is really not an option. I have to handle a lot of tasks over the network while on calls.
Anyways I would appreciate it if others could post if they are experiencing these issues and give as many details as possible so we can try to isolate the root cause of this problem and if found to be a carrier issue we can escalate with them. Thanks

Call Ended Issue Resolved
Hi All,
I see this Call Ended Issue in many brands. So I assume the error is a combination of the Network along with the SimSlot.
I tried various combinations for my Moto-E mobile.
Before i post the solution i found, Let me provide a brief about the problem.
I use Vodafone network on sim1 slot and Uninor network on Sim2 slot. I started facing the call ended issue on my sim 1 vodafone network.
I inter changed the sim's and found the network working absolutely fine. This makes me to understand that the sim1 slot with the vodafone carrier has some network issue where that IMEI code has some problem.
i tried to place the vodafone sim again on the sim 1 slot and found the problem persists. So i came to that conclusion.
Hope this might help you and provide a instantaneous and temporary resolution.
Thanks,
Praveen.
Call Ended problem still going...
Hey,
I just rooted my Moto X (XT 1053), like 5 min ago, in the hope to fix this same problem. I`m no programer/developer and have nothing against rooting, I just don`t think I`m that kind of user. Anyway, about a week ago my phone started to drop my calls right after dialing. I restored factory settings, updated it and nothing worked. I took it for service and they offered to charge me 150 bucks to restore factory settings and update the software. So I was kinda forced to root and try to fix it this way. The problem is that I probably don`t understand half of what you guys say, so if there are any kind souls out there, please help me out.
To sum it up:
- No Sim Card error
- I get carrier services and can use mobile internet (3G because 4G is still too explensive here in Brazil)
- Directly drops my calls
- Won't receive calls
- Won't send or receive text messages via carrier (just over 3G or wifi)
I`ve tried another carrier's Sim Card, no go.
I`ve tried my Sim Card on another phone and it worked just dandy, so I really don`t think it`s carrier related.
I`m running Android 4.4.3, as the other updates weren`t available for my phone via Motorola. I thought maybe updating to a newer version of Android might do the trick. I just have no clue on how to do that on a rooted phone... or on a non rooted phone for that matter.
Can anyone give me any tips/pointers/etc... ?
Thanks!
I have the same issue with my moto x on Verizon. Have you been able to figure it out?

No sound no pickup issues

Hi, happened 4th time this week (never before): I picked up the call but heard no sound ... and the other person later said that their device didn't register the pickup (as if I didn't). But other calls were ok, in one case a call from the same person a few moments later
Any recommendation how to approach this? Can this possibly be an issue somewhere on the way and not in the device?
Ideally without factory resets or handing the phone off for repair...
Thank you!
I have had issues like you said in the past, switching to gsm, 3g or 4g semmed to solve it
Disabled LTE for calls, didn't get too many so far, but they were all good. So hopefully this is solved, thank you!

Question S21 Ultra sometimes doesn't show that someone is calling me

Hello,
For many months I have had a strange problem with my S21 Ultra, namely it does not seem to show me at random times that someone is calling me, no matter if via the cellular network or some communicators, it simply does not show notifications that someone is calling no matter how is calling. I often have it that only when I pick up the phone, unlock it and check something on it, suddenly messages come that someone tried to communicate with me, and only from then on I can answer calls until I hang up the phone and in an hour or two the same problem - over and over again. I have such an impression as if the phone itself went into some hibernation after putting away, although I have no indications that something like this is happening, because everything looks normal. The phone has the latest update, and I have restarted it several times with no effect.
I would like to add that this happens both in an apartment where I have wifi turned on (I do not use lte calls), and when I am outside while walking in the city.
Is there something I can do to fix this?
This is a very strange issue indeed. Have you checked if your phone has cell coverage when the screen is off? Did you try calling yourself from another phone and number? If the answer is negative to either question, I would suggest resetting your network settings. If that fails, try a factory reset which should solve any issues. If the issue still persists, it could be hardware related and you might need to take the phone to Samsung centre to get it checked.
I don't have a second phone to call myself. Friends say that on their end it sounds like I am not answering the call (i.e. they have a call signal, but just nobody is answering). They have no busy or unavailable signal. What exactly do you mean by a network reset, what would I exactly have to do? I was thinking about a factory reset, but I'm afraid that I will lose all my data and application settings. I do not know if it matters, but I have been using this phone since the premiere of the S21 Ultra, and when I bought it, I transferred all data via the data migration service from the previous S10+ phone, to which a few years ago I similarly transferred data from the S9+, to which I transferred data from S8 + earlier
Maybe you have the "do not disturb" option on? When I have this on, I can't see who is calling me.
I checked, unfortunately it's not that, if it were, I would never see someone calling, but my problem seems to be random.

u need to go to settings>general>reset and there tap reset network settings..
Hi,
I experience very similar problem. I tried to reset network settings, "hard" reset the phone, playing around different mobile network settings... nothing helps. I'm not sure if it is phone hibernation issue or kind of removal of the phone from cellular antenna.
I have another phone I use to watch this s21ultra issue. Practically each day it happens that the s21 ultra does not react to my call, of course most of the time it works properly, but there are some tries, when it fails. In such case on the phone I call from I get a message "user is not available". But then, leaving the s21ultra untouched for 10 minutes I get SMS saying that someone tried to contact me, so it is not obvious that the phone hibernated.
I was not able to reproduce the problem on the other sim card put in s21ultra (the carrier is different). I was not able to reproduce the problem on the other phone and the sim card from taken from s21ultra. In my opinion it is related to "weak" mobile signal and kind of "sensitivity" of s21ultra to low signal quality.
I reported the problem to my mobile network provider, but I'm still waiting for the answer. Anyway, I'm going to do the following:
- ask for sim card replacement (cheapest option),
- (if above does not help) go to samsung service and ask to check the phone - I hope they have some diagnostics tools,
- (if above does not help) install the second sim card (from different provider) and configure redirection of calls in case of "user unavailable" - I know it is "stupid" solution - but at least one of the carrier should work
- optionally root the phone - Can anyone confirm if it may help? At least I could enable toggling airplane mode each minute
