Nexus 4 - No Service with specific carrier

Hi,
I have Nexus 4 for about 3 months, and I was using it fine with my SIM cut as micro sim in my carrer.
On Friday night, I put it into airplane mode and went sleep. On the morning I disabled airplane mode but the carrier signal didn´t came back.
I tried then put my micro sim into another phone, and it worked fine. I other carrier micro sim in my phone (also cut from normal SIM) and it worked just fine !
I already tested 2 micro sim from my carrier and all of them gets the same, N4 says 'No Service | Carrier name' but with another carrier, it works fine (tested with 3 different micro sim, from this same other carrier).
I called to my carrier asking if there is something blocking my phone, but they say everything is fone every time. (Btw I discovered that my sim was blocked for some reason, but it is now unblocked - so I´m thinking if they did not blocked my IMEI, but they say no every time).
If I go to the Mobile Networks -> network operators and choose my carrier from the list, it says 'Selected network (XX) unavailable'. If I choose automatic, it does not give me any error, but the 'No Service' text...
I already tried factory reset, reboot, airplane mode, flashed google factory image, flashed radio .33, .48 and .54, flashed CM 10.2... nothing...
My question is, is any way, techinical way speaking, that my phone has 'broken' something that avoid me to use only a specific carrier? Because my carrier adivce me to take it to repair, as it is the guilt on the history, but I´m thinking it is very strange that it work for another carrier but mine...
Is that even possible ?
Thank for you help !

I'm having the same problem here, I've tried to flash back 4.2.2 ROM and then 4.3 stock but still no better. please any1 help us :crying:

Have you checked APN settings? I've seen it sometimes default to the wrong one if there's multiple in there. Who is your carrier?

It happens to be in my case, a problem with the carrier itself. I tried others SIMCard from same carrier, and got the same issue. Tried from a different carrier and worked just fine.
After a long fight if the carrier, I found out that my IMEI was on blacklist only for that carrier and after another long fight, I could get it unblocked and everything got back as normal...

I have the same problem with my nexus 7 2013 LTE, my carrier is always unavailable other 2 carriers in my country are just working fine. why would a a carrier put IMEI on a blacklist? I want more info about this problem if you pleased.

They have a lot of reasons to do that. In my case I believe that the cause was my phone got stuck with something and start to consume a lot of 3g data. As my plan do not allow tethering, they identify this high usage as tethering and blocked both my simcard and my IMEI (even that at first they swear my IMEI was not blocked, but after I opened a ticket in government regulations, they fixed it).
If it works with 2 other carries, do not work with other sim cards from your carrier and in past it worked fine, it is 99% sure that your IMEI is blocked at the carrier, I would say

Moto x pure not registering onto GSM sim

Hi,
I have a Moto X pure 16GB (xt1575) bought from USA. I used it on multiple carriers in USA and it worked fine.
I am on a visit to India, where I intend to use the phone for couple of months.
I tried with these networks:
CDMA sim (Operator Tata Docomo) - Network gets detected and sim is operational
GSM sim (Operator Airtel) - Sim is detected but doesnt get registered onto network
GSM sim (Operator Reliance Jio) - Sim is detected but doesnt get registered onto network, seems some problem with Jio network, they have additional things for VOLTE to work.
So, I am pretty sure, the handset is fine, changed the network settings thru the secret menu phone info, to LTE, GSM to what not. nothing works for Airtel Sim.
The bands do work in India and are compatible.
Any idea's what more can I do?

The rom is stock and generally dont fiddle around with the ROM's as I have never done it.
Can try it if nothing works.
I am noob, a procedure would be helpful or a link to it.
Thanks.

Apn?

It does show the Apn, but the gsm service shows as unknown and network type as unknown.
Any users from India have any suggestions.

AIrtel and Jio work fine on the Moto X since many users here have and are using it with them, except the VoLTE part of Jio you have to use the Jio4voice app to make/receive calls.
Have you tried going into the Phone app, dialed *#*#4636#*#* and gone to Phone Info and changed "Set preferred network type" to something different?
Also, I think the Jio SIMs require a very specific registration process, going through several apps to get them working... check with a local shop.

Here's some snapshot from the menu screen and network finder applicaton.

I know the ans to this soln
i am a jio user and basically the problem is that mxp supports volte but the frequency is the main issue.. due to unmatchable frequency the volte ain't activated for jio
u can try t&t and Verizon sims volte is working on them but jio frequency is not up to that mark as mxp but an official nougat update might help the frequency to maintain and volte might get activated.....
so we need to wait for official nougat update only... trying romcwont work..
screenshots are here

Thanks for the response, I will wait for the Nougat update.
Does the same apply for Airtel also ? It shown network type as unknown.

Unable to register phone on T-Mobile network

I've been a T-Mobile customer with my OnePlus 1, got the OnePlus 5 today and went by the local T-Mobile store and got a new SIM card. A couple hours later I got around to actually setting up my phone. I realized I wasn't getting app verification codes, so I called T-Mobile to make sure the SIM card activated properly. She had me confirm the SIM card was inserted properly, then she had me turn the phone off and she "sent it a signal." That got text and data working, but still no go on the phone. She transferred me to the next tier up tech support. On the phone with them, we turned off WiFi, WiFi calling preferred, VoLTE, and automatic selection for Network operators. The phone did it's search and we selected T-Mobile 4G for the Network operator. The phone says it registered on the network, but T-Mobile says it didn't. We tried the second SIM slot but no change. We did a couple reboots and still a no go. I was then told that since it's not a T-Mobile branded phone, they can't guarantee that it will work. They recommend I put the SIM in a T-Mobile phone to confirm that the SIM works - I'll do that when I get home and try it in my wife's phone.
When I turn on VoLTE, I get text and can make calls, otherwise if I make a call, it just calls T-Mobile.
Under Settings > About phone > Status > SIM status, Cellular network state shows disconnected.
I also see under Settings > SIM & network > SIM 1 > SIM name it shows the name as T-Mobile but Carrier says Unknown
Fresh out of the box, running 4.5.3. Has anyone else had any problems getting their OnePlus 5 to register on T-Mobile? I searched the T-Mobile support site but didn't find anything helpful.
I'll try the SIM card in the wife's T-Mobile S7 when I get home, but if anyone has any pointers, I'd appreciate the help.

OnePlus 5 on T-Mobile here and no issues at all.

Same here. I also have 0 issues
Are you using the latest 4.5.4 update for OP5? They had fixes for VoLTE not connecting. Even though I think that was Europe only thing, the download made its way to my phone automatically. If you're not on 4.5.4, go upgrade (it's a simple thing to do)
What are your APNs set to?
Goto...
Settings
Sim and network
Sim x (1 or 2, wherever the sim is installed)
Access point names
Without doing anything besides entering my sim card into the phone and starting it, I have 4 options
If you have anything outside of your current provider, add them. The easiest way to do this is to open up another TMobile phone you have, goto to the same location on that phone and copy settings manually to your OP5.
I did this for my wife's S7 coming from Verizon. Although she doesn't get WiFi calling without flashing firmware (which I'll be doing when she's ready) you shouldn't have that issue.

Bad SIM card
Turns out the SIM card was bad. Went to the T-Mobile store, let the guy double check everything, then he grabbed a new SIM card, popped it in and two minutes later everything was working. I asked him how often he sees bad SIM cards, he said one or two a year.

Does it say Sim not present? If not, go online and search for APN settings for whatever network your on and enter them in as listed. On the screen you posted, click "access point names" and transpose the data from whatever your carrier's APN settings.

Can you raise this in guide section ->uicc unlock post. you can ask for modem partition from someone who has openus variant and can flash those ones. Did you also check your sim in another phone

Maybe i dont understand but it looks as if you have 2 APN settings profiles yet you don't have either selected.

I glanced at these but didn't read the whole threads. Pretty sure they address sprint sim card locking post update. It may be worth reading about to see if yours is a similar situation. Good luck man.

I'm kind of in the same boat, essential phone openus variant with no service. I've tried different things and have been able to get it to work but just for some time before it gets no service again or some odd behavior. I don't get invalid sim or no sim notification, it is a no service notification, apparently it recognizes SIM and accepts it but is not able to find a network, as if it were out of coverage or mobile radio off. SIM card has been tested in another essential phone at same location and works flawlessly.
So far I've found that if I downgrade software to nougat and then update to oreo or pie, and then insert SIM, phone is able to get LTE connection, receive or make calls, it works fine. But then after a couple of hours or even half a day, it gets no service again. Network or factory resetting doesn't do anything, changing network settings neither,then after If phone is restarted with sim in or if sim is inserted while on, it immediately shows voicemail notification but there is no way to retrieve it of course.
Most of the times at network settings it gets and shows the correct apn but it doesn't let to choose network manually, it turns back to automatically and says no networks available. Some times I get a rare relation with wifi connection, if wifi is on and connected it shows carrier name as if ti was connected to network but no calls in or out, as soon as wifi is turned off or disconnects, carrier goes back to No Service.
Maybe someone knowing this has some idea of why phone has this strange behavior which makes it useless as a phone.

I think your phone locked for Sprint like mine , call them to unlock it .
mine is unlocked From Sprint now , but i sill need a Sprint Sim to complete the unlock process which i didn't get yet , I don't know where i can get one (I LIVE IN MOROCCO)

I guess it's possible but I really don't think that phone could be locked to sprint. I understand although sprint variant is supposed to be locked, most users are able to use other carrier sim, and only the pie update has shown invalid sim, which is not this case by the way.

mine is not a Sprint variant , and somehow is locked to Sprint , it was previously purchased From Best Buy . but after installing Pie on it , it shows no service , i called Sprint and they said it's locked to them
than i made an unlock request and they unlocked it

ok, so maybe flashing modemst images for openus variant could solve the problem, I don't mind trying if they come available but haven't found them yet.

Voice calls not possible on Lebara network Australia

I've got a very weird issue with my Galaxy S8 (SM-G950FD)
After working fine for about 1.5 years on the network it suddenly wasn't able to make and receive calls anymore on the Lebara (Vodafone) network in Australia.
The issue spontaneously disappeared a few hours after it first surfaced but reappeared and has not gone away since.
Internet and Txt/MMS are working normally. But when someone calls me it goes straight to voicemail and when I call nothing happens for a minute or so and then it "disconnects" but no tone
When I go into the phone app and try to retrieve settings like caller ID and/or forwarding it gives the following error:
Failed to read data
Something went wrong. Check your
Sim Card or network connection,
then try again
When I insert the sim into an S7 it's working. When I insert the sim from the S7 into the S8 (Optus network) the S8 works as well.
I've performed a factory reset (without restoring the settings)
I've gotten a new sim and Lebara has ported the number to it but that didn't help
Being a dual sim I've tried using the shared sd/sim slot but same issue.. data/mms/txt working no voice.
I've tried copying the apn settings the S7 displays with the Lebara sim to the S8 but that didn't help either.
I've now used Odin to flash the phone back to the Oreo version with the December 2018 security update and that didn't help either.
Any other ideas?
Thanks

I've managed to narrow down the issue a bit.
Also went out to purchase a Vodafone Pre-paid sim. That one didn't work either at first but after some troubleshooting with support of Vodafone we've found out that the S8 doesn't connect to the 3G network of Vodafone Australia.
When I have the SIM of another provider in there and limited the network mode to 2G/3G autoconnect the phone just finds the 2 other networks on 3G (AFAIK 2G has been phased out).
I've tried to get into the advanced service mode but this doesn't seem to be possible anymore.
Is there a way to try to see which bands are active on the S8 and better yet enable them all?
