[Q] N6 - No incoming & outgoing Calls, mobile data gone.

Having my Nexus 6 for almost a month. Things working perfectly in the starting(or after reset), but after two or three days, No incoming calls, no outgoing calls. No mobile data. Cant realy tell it as a mobile sometimes. Wifi is working good always. After reset, it is working properly for two or three days. Whenever it is not working, I am able to see a !-mark near the tower bar.
My mobile always connected to 4G when no wifi.
No Custom ROMS and no root. Plain Android given by google.
Anyone having this issue. Any suggestion?

Go get a new SIM.

I was begining to think i was the only one who had this problem!
Yesterday morning i woke up and to my suprise my signal bar had a (!) it it but it was still displaying my regual signal level.
I switched my wifi of and i couldnt get a data connection just the (!) sign. I got my girlfreind to give me a ring and see if a
call would go through which it didnt it just said that i was unavalible. I then desided that a reboot might sort the problem
but when i my phone booted back up i was presented with the holow triangle signal icon to say that i had to signal. I then
popped my simacard out thinking it could have just been a bit of dust on it. I gave it a little bit of a dust of and popped it back
into my phone and i was given the same no signal and emergency calls only yet it was picking up that there was a simcard inserted.
The day before i had flashed the alpha version of PA so my next thought was that this would be a ROM bug and went ahead and
flashed chroma which i was using prior to PA and i had had no issues with. Held my fingers crossed as it booted up but much to my
dismay i was greated with the same no signal problem but i went into the settings and searched for networks. Three was one of
the network it had picke dup so i tryed to reconnect to it but i got the toast to tell me i couldnt connectto the network and to
try again later. I checked the APN settings and it had automatically grabbed threes APN from the sim card so at this stage i was
completly baffled by them problem.
My next move was to try my sim in my girlfreinds phone and what do you know it worked a charm. As a last shot to check everything
was okay and i was upto date on my bills etc i gave three a ring and they told me there was nothing wrong with my sim and everything
was working as it should be and that it was a problem with my phone.
That brings me to the point i am at now completly baffled as to the problem and slightly angry at the 2 week old phone that had been working
perfectly up until now has suddnely desided to stop with no warning.
So you are not the only one and i expect their are more of us. I am going to flash the offical stock rom from google and see if that does the
trick but im not holding up much hope i feel like im going to have to contact google and find out where the problem lies.

I got this as new nano SIM from the retailer and seems like working in all other mobiles except Nexus 6. Also I can see lot of people having the same issue with Sprint Provided in US. One more Victim replied too.

i reverted back to complete stock using the image from there site to no luck so i relocked the bootloader and took it back to the carphonewarehouse and they straight swapped it for a new one which is working perfectly

My sim died after a month. My calling went out and then only lte worked no 3g. Got card replaced and it works perfect now. I have US Cellular.

I've posted this in few other threads also, but I had also problem where I only had tgt exclamation mark no matter what I did. I solved the problem by waiting like 5sec before inputting my pin-code. If I input my pin code too fast after a boot, it will open my phone, but won't give me cellural network. This seems to happen in every ROM I've tried

Hi,
Solved the issue. Working fine after enabling request for SIM Pin and set my sim pin.
Usually i disable sim pin lock to have uninterrupted boot. But with ROM this is not working.
Enabling SIM pin request solves the issue.
Is this problem with carrier or Android L?

I have not seen this issue on three devices I've owned with Lollipop. So it appears to be a carrier issue?

HTC One M7 No Network with Working SiM

Hey guys, I've been recently having a problem with my HTC. Basically my phone seems to be not receiving any network even though the phones reading the SIM. I thought it could've been my SIM card so I rang my network provider and they sent me a new SIM. But still the same problem because ive tried the SIM on another phone and it works perfectly fine.
I've tried to factory reset the phone yet it hasn't solved the problem
A very unusual thing happens as well. Sometimes I will get full service or a few bars and if I try to call anyone then nothing seems to happen - it hangs up after 5seconds. I've also tried to use data when the service comes on for a bit and sometimes it comes up with E which is 2.5g i think? So very slow speed. However this works for about 5s then the network goes again.
I have tried to manually search the network and it sometimes finds it and sometimes doesn't.
Really not sure what the problem is and very concerned the phone is over 2 years old but still looks brand new!
Would really appreciate if someone could help me. Thank you in advance!

[Q] Experiences with AA and Dual SIM Phones

Hi all !
Does anyone of you also have issues when connecting a Dual SIM phone to AA and trying to place & receive calls ?
In my case - when i connect my OnePlus X (CM13 Custom ROM), AA and the Phone crashes if i do not set a default SIM for outgoing calls in the Phones SIM settings (Option "ask before each call").
I couldn´t try with Stock ROM because this caused Bluetooth Errors with the Cars Media System (no Contact Sync)
Headunit is a SEAT Media System Plus (Alhambra 7N 2016)

Hello fellow OpX user.
I've not got a secondary SIM so can't answer your question. However we are both using the same phone and head unit so I was wondering what your experience with AA is like?
I'm on stock and although it works well I do seem to get constant disconnects, especially if I'm travelling on a specific section of road I can guarantee it'll disconnect there.
Do you have issues this issue on cm13?
Oh and I fixed the Bluetooth contacts issue with an app called Bluetooth Phonebook. Just the HU can't read text messages

I think it is because of your ROM. I also use a custom CM13 Rom (Mokee, on a nubia z7 mini) and for me it works. The disadvantage however, is that I have to select which sim to use on the phone. So it does not offer me a choice on the headunit but only on the phone itself. If I do not select a sim on the phone, the call simply does not go trough.

Hi !
I'm running Sultans CM13 Rom for almost 3 months now and it's working perfectly well.
I have nearly no disconnects in AA and Bluetooth is also stable (phonebook, messages...)
The Problem i described in my first post was caused by my flip cover - when it's closed while connected to Bluetooth handsfree and i place a call the phone APP crashes - seems to be a common bug caused by proximity Sensor.
-> not ROM related..
At least for me switching to a custom Rom was the best decision....

Cheers @error23 that's interesting that you have no issues on Sultan's ROM. I'm beginning to suspect my issues lie with either GPS signal (but I think that'd be more random) or when switching between certain types of Cell Masts as it's always in particular locations or routes.
Out of interest, which country are you in and do you know which bands your network uses for LTE? I'm in the UK on o2 which only uses band 20 for LTE.
At the moment I'm running the OnePlus marshmallow community build.
Thanks

I'm in austria on the 3 network - using LTE Band 3 (1800MHz) and 7 (2600MHz). I have no disconnects when changing cells, even not when it falls back to 3G or national roaming (which is 2G)
But - as mentioned - OOS didn't run stable with AA for me and i expect its Bluetooth related, but who knows

Guys, how did you solve that dual sim select when calling using Android Auto?

I am afraid there is no real solution. I still have to select the Sim card I want to use on my phone. It looks like Android Auto is not really ready for dual sim use. When using voice dialling however, it once asked me which sim I wanted to use. To this day, I am still waiting for it to happen a second time since it looks like a very useful feature.

I am using a Moto Z Play with 2 SIMs. The issue I have is that I am able to make phone calls from Android Auto ONLY if the SIM being used to make the call is the same SIM which is being used for data at that point in time.
I am unable to make the call if I use SIM 1 as my default Data SIM and SIM 2 as my Default Voice SIM and vice versa - the error I get is "Network not available".
I thing this is a serious issue that needs to be addressed.
Incoming calls seem to work fine though.
Anybody with similar experiences?
Best,
Krish

Yeap, that's me, unfortunately. I am waiting for a possible fix by Google, because it is rather uncomfort having to disable the 2nd SIM each time I enter my vehicle.

I am using Xiaomi Mi5 Global edition running Android 6.0.1 on MIUI version 8.1.2 Stable. Android Auto version running: 2.2.710804-release. Exactly same issue as yours.
My default SIM setup: SIM 1 for data and SIM 2 for calls and text. When using only one SIM for both calls and data, Android Auto works fine. However, with my dual sim setup, I get "Network not available" when I try to make calls. Incoming calls and texts are working fine though...

Hello,
Oneplus2 Oos 3.5.8
After some test I confirm that using same default SIM for both call and data is needed to use outgoing call in AA. If not (or if call setting is 'ask everytime'), I got the Network not found message.
Yesterday I did a real quick test with the app Dual Sim Selector Pro using basic settings. It did work, even if I was very surprised. Later I bought the app and start to configure my phone.
This morning, it was no longer working.
I was going to give up and I read this message about the android setting needed to be similar in data and call.
IT SEEMS TO WORK!!!!
My setup:
SIM 1 is for private matter and I use mostly this one for data
SIM 2 is work related
In Android settings:
Default call: SIM 1 (my dream setup was to use SIM 2 but w/e)
Default SMS: SIM 2 (mayble i'll have problem to use sms app but I dont use it while driving)
Default Data: SIM 1
In Dual Sim Selector pro:
Main screen: activated, SIM 1 as main
Automatic select screen: activated, and in group tab I've go my works groups with SIM2 and private groups with SIM1.
When using Android Auto, the calls are made with the right sim!!!!!

Anyone interested in a dual sim add-on for AA?
Hi everyone!
It is quite a while ago that someone last posted in this thread. So far I was reading in this forum regularly but did not post anything yet
Since I use a dual sim phone (Samsung Galaxy S10) with my private and my business sim card running in parallel I also was facing problems when dialing while driving with Android Auto - in phone screen mode, but I will get a new car with support for projection to in-dash head unit soon . AA does not allow me to select the sim card to dial with for the next call when Android Auto UI is shown.
This was anoying me so much that I started to develop a simple Android app which allows my to select the right sim card easily while driving. It is a kind of unofficial add-on for Android Auto. It is doing the job well now but is only tested on my personal device.
Are there other dual sim phone users in the XDA community that are interested in using / testing my helper / add-on app? If so I would try to publish it in Google Play Store as a public beta. It is free! Please give your brief feedback in this thread.
Regards, Gero

Hi, I'm a 2sim user with a opel mokka car.
Don't know if my AA is up to date enough but if you want, I can du a try. Write me in PM if you want

Hi, thanks for answering. Currently I am stuggling with getting the app approved by Google for publishing on Google Play Store. When it will be publically available for download I will invite you for beta testing

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

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
