[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?

[Q] Dual sim adapter support for Nexus 6 (STK apk)

Hi everyone,
I know this is an obscure one and I may be the only one who wants this sort of thing but I live in the mountains and like to use T-Mobile but also keep a Verizon (PagePlus) SIM on hand with a cheap plan as sometimes I have to enter T-Mobile roaming areas and need more data than is allotted for roaming use.
Anyway, I have a Verizon Moto X (XT1060) and a dual sim adapter which works awesome (i.e., I can switch back and forth between T-Mo and Verizon service without rebooting using the Sim ToolKit (STK) app, which pops up when the phone sees the dual sim adapter installed).
I've installed the dual sim adapter in my Nexus 6 (Play Store unlocked version) and while the Sim Toolkit does seem to pop up once the adapter is inserted (and the T-Mo SIM seems to work still - see attached screenshot) it then crashes when trying to switch between sims and disappears from the launcher altogether (you can try and resurrect it via a "Activity" in Nova Launcher but it still doesn't work and just says the app isn't installed). In doing some research it seems like the STK apps in AOSP ROMs don't work very well (which might explain why this scheme works well in the Moto X) but I was curious as to if anyone has had any experience with this problem.
Since the Nexus 6 has such unbelievable cellular radio support across pretty much any network, CDMA and GSM/LTE alike, it seems like it'd be a great platform for the use of a dual sim system, which is why I'm kind of surprised it wasn't a dual sim phone to begin with...expecially since Android 5.1 is allegedly adding dual sim support but I think that may be mostly just a GUI to facilitate switching more than anything else.
I'm running the May 14 Euphoria 1.1 (OFFICIAL-20150514) with baseband MDM9625_104446.01.02.98R. I've tried a the .95 baseband as well, to no avail...and rebooting after switching SIMs doesn't seem to work either (and neither does just "waiting" a minute or two). I've also tried the stock ROM and it doesn't seem to work either...same sorts of issues. Finally, I should concede this might work better with a GSM / GSM SIM situation as opposed to a GSM / CDMA/GSM situation so perhaps it's a lost cause.
So yeah I just thought I'd throw this up in case anybody had any ideas on how to make this work.

No idea how, but out of interest, which adapter have you got? I'd like one.

Hi! I got mine on Amazon...XDA won't allow me to post a URL but the name of the accessory is "LOPURS 2 in 1 (Dual SIM Card Multi-SIM Card + Tray Holder) for iPhone 5/5S/5C(Dark blue)." Even though it's for iPhones allegedly it does seem to work ok on the Android platform as well (at least, on my Moto X).
It's definitely weird looking but with a case around the Nexus it seems to fit alright.

Here's one for the Samsung Galaxy S5 on Amazon, but seems there's quite a few different ones to choose from:

Curious with the 5.1 update if this will work natively. It's been advertised that dual sim support is built into 5.1.
What's your experience? Any updates?

Unfortunately the adapter doesn't work with 5.1 or 5.0...one is able to launch the 'Sim Cards' activity (this gets you to the new SIM Cards settings menu in 5.1) via Nova Launcher by setting up an Activity widget but since (I think) the adapter can only work with one SIM at a time (it seems to block one or the other altogether depending on which is selected) the new functionality in 5.1 appears to not be useful in working with the adapter...I think it'll only work with phones that are dual-SIM by default.
I accidentally destroyed my last adapter (they're extremely delicate, and are hard to install with SIM tray-type phones) so I'll try this again once I get a new one using the Android M developer preview...fingers crossed!

Thanks for the update! 'Preciate it.

So...this can be marked resolved. It turns out that the Nexus 6 accepts the dual SIM adapter just fine (takes a reboot or two, but it eventually settles in and works great) and I successfully used it with two T-Mobile US SIM cards. The issue was the Verizon SIM containing some sort of CDMA code that was (I'm guessing) fouling up the changeover and crashing the adapter's firmware and/or the STK app. The odd thing is that it did work on my Moto X XT1060...but after trying again I noticed that voice support never actually worked on the Moto with the SIM adapter installed (nor did eHRPD or 1X data - only LTE worked) so it appears that CDMA just isn't compatible with the adapter(s) I've been using. I did see that MagicSIM offers an adapter that's allegedly compatible with CDMA but I'm a bit skeptical honestly and these adapters are just too delicate to spend $30-$40 on.
So, in conclusion, this functionality is absolutely do-able but it requires two GSM SIM cards as opposed to one GSM and one CDMA/LTE.
In any case it'd be totally awesome if LTE/CDMA-GSM changeovers could be accomplished with a different adapter...so if anybody ever has any luck with that please post! Thank you for the replies.

With the GSMx2 sims, how much functionality did you get? Could you receive calls on both numbers? Did you get a prompt when dialling which number to call from?

Unfortunately you only get very basic functionality. All the adapter is capable of is switching between the SIMs...once it's switched to one or the other it can only see that one SIM. You can set it to automatically switch back and forth in time intervals but I bet that can get really annoying sometimes if you're in the middle of a call or web browsing session or something...not sure if the adapter is smart enough to know not to interrupt a call or download with a switchover...I bet not!
I know that actual dual SIM phones can do what you describe but unfortunately none that I've been able to find have the vast frequency support of the Nexus 6 so it's kind of a conundrum...I really wish Google had made the Nexus a dual SIM setup...big missed opportunity IMO.
But in any case the adapter can help if you're a frequent traveller or have a work and personal phone or whatever and you don't wish to swap SIMs all the time...or if you're like me and just need two carriers to fill in each others' coverage gaps and can use Google Voice to route your main number to both carrier numbers.

That wouldn't be too bad I suppose as long as a reboot isn't required. I forward work to personal anyway and just turn work phone on when I need to make a call.

Huawei P10 Dual - Can I assign Specific Contacts to be called by specific SIM card?

Hey all,
I recently purchased a p10 Dual.
I have 2 SIM cards.
a. Personal number
b. Business number.
I want to assign my Colleagues numbers to be called always and without the phone asking me every time, with SIM CARD b.
And all the other Calls to be made by my personal number.
I really can't find a way to do it, and I am definitely NOT technologically challenged.
Any insights?
Thanks in advance!
Dimitris

I have found no such thing either, BUT as there are two buttons for calling in the default phone app, it hasn't been such a problem. Also, if you pick a contact from the contacts list, the popup for calling will show which of your SIMs was used to call this number last time.
Another thing that amazed me, was how the integration with in-car hands free works. If i pick or enter a number with the car system, it actually automatically uses the last sim used to call that number. So you dont have to worry about choosing.
When calling from the phone, I guess it is a little bit more tedious to get used to huaweis method (I came from a dual sim LG G4, and there you had to swap SIM card calling, but you could assign numbers to sims so it would pick the sim automatically), but it took me around 1 month to not notice it any more.
There might be some third party Phone apps out there that can do this, but most of them are not that good overall - and googles own does not work with dual sim phones as far as I know.

I've been using True Phone for many years - previously with Xiaomi double-sim, now with Huawei - no problems at all. You can assign numbers, save the latest used as a default, etc.

I get that, but I still can't even imagine why the Car mode can memorize which SIM card Called Which number, but this cannot happen to the non-car mode.
Especially since this feature existed in much older android versions.

Thanks for the tip. I will check it out. Although, using a Dialer in 2018 is not my best choice. It reminds me my Experia X10 and its terrible UI.
I tried Dual SIM selector.
The basic principal works for me, but it doesn't work every time, and it is tiring.

Whatsapp and LTE/HSPA+

Hey guys, i've got a very special problem i think. I have two sim cards in my XZ2. Both are registered in 4G. Now everything works fine. I can use every app and download files. The only thing that doesn't work is Whatsapp. If i switch to H+ then Whatsapp works but not in 4G. I had a lot of android phones but this never happened to that only one app doesn't work on 4G. Has anyone experienced something like this and can help me/give me an advice?
Edit: After trying to fix this Problem i think there is following situation: in the settings you can choose the sim for data connections. For me its sim 2. But whatsapp is trying to connect to the internet over sim 1. when i change the sim for data to sim 1 everything works fine. So imho this has to be a software problem. I hope sony will fix this soon. Do you think talking to Sony support might help?

Hi heildnix, I have an XZ2 Compact, my situation is: SIM1 LTE/voice, SIM2 only voice. I've set SIM1 default for all (data, voice, ecc). all works apparently fine, but! I don't know why WhatsApp try to use SIM2.. so if I have SIM2 active WhatsApp does not work..
I opened a ticket to WhatsApp and Xperia Care and... if I went for a bike ride I would have obtained more results

Question Anyone Have ZenFone 8 on Verizion?

it looks like it has the right frequencies to operate on Verizon, and it will initially connect to the network on boot, but then drops off.
Any ideas here?

Hi - Mine arrived over the weekend and I put in my Verizon 5G sim card and i was able to connect to verizon data network. All things data worked.
But I can't place or receive calls as volte isn't working (my account has volte active). I don't have 5G where I live - so I'm on the LTE network.
I opened a support case with Asus this morning - they said to wait 24 to 48 hours for their engineers to review it. They originally told me to call Verizon, which Verizon told me they can't help. Verizon said Asus has to work with them to get the phone certified. I'm not sure what to do at this point except wait for Asus to reply. I will be returning it if they don't get it sorted out very quickly.

Out of the box I had data only without ability to make calls. After rooting the the phone and installing LineageOS I was able to make calls and and operate the phone on Verizon network without any issues.

Can anyone confirm this? And if so, why does LineageOS work, but not the default ROM?

I just tried it and it depends. I had the exact same symptoms:
- Data worked fine
- Texts works fine
- Calls didn't work at all
And I installed lineage 19 and then everything is normal and great. No idea why though.
EDIT: I installed lineage 19, staxisos, omnirom and all had this problem:
- Data fine, calls, fine, texts could send
- Couldn't receive texts.
After the level 2 verizon tech told me the phone was a loss I returned it. Now after doing a ton more research I found out that it might be because I simply took the sim from my old pixel 4 and popped it in. It seems you need a new sim card or you need to somehow have your line switched to be "cdma-less". Looking at these articles:
r/verizon
r/SonyXperia
OnePlus community
The guide presented on the oneplus community gives me hope I could still use this phone with verizon, but it appears to be a daunting task. If anyone has navigated the customer service and succeeded with this specific phone, I might rebuy it.
