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...

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
But a S5(SM-G900W8) second hand that was described as unlocked on Jan 5. From the kijiji ad looks like they were using Telus. Put my Fido SIM and and off to the races. Except it wouldn't update. Flashed with ODIN to Telus firmware from SAMMOBILE. Still working fine.
Until Jan 14th. It just stopped working. Says unregistered SIM. Tried that sim in a G3 and it works no problem. Tried working SIM from G3 in S5 and no go. Took it to Fido store. No help but they did give a new sim. Can read SIM information using app.
Not blacklisted with Fido/Telus/Bell/Virgin/Koodo. Called them all. All of those providers have no information on phone when searching by IMEI.
There is a Bell TV app on phone so I thought maybe it was originally Bell and went to a store to see if they had any info. No info but girl in store tried her bell sim and it worked. I assumed that somehow in the firmware/software upgrade process it had lost it's unlock and must be back locked to bell. Tried to unlock it from Bell but it fails says IMEI not in database(from internet unlocking service).
Still thinking it might be locked called all providers mentioned above to see if they know anything. Nothing. Sidenote when I put my Fido sim in it just says unregistered SIM. Does not pop up for an unlock code or anything.
Tried a friends Rogers SIM. Unregistered SIM. Drove to Telus store to try a SIM. It worked but no service because it was not tied to an account(but did pull Telus APN's from connecting).
So it appears as though Bell/Telus SIM's work. But Fido/Rogers say unregistered SIM.
Called Fido again and they had me go through all the manual APN setup etc. Then something about sending a new signal to phone from Tower to reset network settings. Didn't work. Fido has no answer for me at all. But yet it did work on Fido for 9ish days.
I'm stumped.
Bueller?
Did you ever fix this issue or find the cause of it?
Hi All
OK... for years I have been using an S4 and been really pleased with it (UK model i9505 SIM locked to EE Network).
Recently I was given a Note3, so have been using this with my EE Sim and left the S4 sitting in a drawer for a few weeks.
This week I ported my number from UK EE to UK Vodafone - so the original contract SIM which I had in my S4 is no longer available to try as it has been disconnected!
Anyway - I sold my S4 to a friend for her son for Xmas and I thought I should wipe it before giving it to her. I had Android 4.4.2 with CWM and also had CerberusApp rolled in the ROM so when a factory reset/wipe was done CerberusApp would still be there. However after doing a wipe I inserted a PAYG EE SIM and it says no service and shows a no entry sign on the top bar. When I put in a Vodafone PAYG SIM or O2 PAYG SIM it shows strength of signal (i.e. no 'no entry' sign) but says that the phone is network locked - which is correct!
But I cant work out why the EE SIM (which is the correct network) wont work. I have tried the EE PAYG SIM in my unlocked Note3 and it all works OK - so I know it cant be a SIM problem.
In desperation I upgraded the O/S to Android 5.0 using Kies and all seems OK but still the same problem. I have checked the IMEI is all OK (*#06#) and its all good - so I am lost why this wont work. Its almost as though the phone has been barred on EE - but its my phone, bought from a work colleague, so not reported lost etc so there is no reason it should be barred.
Can anyone throw in some ideas, or even let me know if there is a way to remove carrier lock on the S4 without doing it through the carrier as my colleague is not with EE now either, so I will struggle to get them to unlock it.
Additional info:
Wireless works fine
IMEI Number shows correct
No SIM/non EE SIM inserted - says not registered on network but see signal strength on top bar
EE SIM inserted (correct for carrier lock) - get a no entry sign and no signal strength on top bar
Model - GT-i9505
O/S - 5.0.1
BB - I9505XXUHOD7
Build - LRX22C.I9505XXUHOD7
Any help would be great as if I cant get it working I will need to go buy one for my friends son before Xmas as I have had and spent the money
Thanks in advance

Bump... anyone got any ideas?
I just bought a factory unlocked Samsung Galaxy S7 Edge, it has the dual sim slots and is the SM-G9350 model. Now, the person who sold it to me said it works on Verizon, and everywhere I search it says it should be compatible. But when I put my Verizon SIM card in, which is already activated, it isn't saying I have service. It recognizes there is a SIM and that it is Verizon, but it says like cellular network unavailable. Am I doing something wrong? I've never bought a factory unlocked phone, I know nothing about it, like where is it from? How does it work? It doesn't even have samsung keyboard or anything. Please help!!!
Did you search the IMEI to see if the phone is lost/stolen? I bought a S7 Edge and the same thing happened to me... I called the network (Telus) and they informed me that it was a reported phone so I can't use it. Kicker is that they can't even contact the original owner! So I had to root it and installed Xposed, now I'm stuck on how to unlock the network or change the IMEI

I did, the imei isn't coming up anywhere because the phone is from Hong Kong or something. But the seller had it activated with tracfone.
Hi, i have an old S5 Neo, which originally came on Virgin, but we used an EE sim card (UK based) this worked without issue, im assuming because virgin use the EE network? but now we are giving the phone to a child and put an asda sim (also runs on EE network) but the device shows emergency calls only and doesn't seem to accept the sim..
IS there a code or way of checking if it is sim locked or not? it is not rooted. codes i found on xda dont seem to work with or without sim inserted..
