Hey all,
having a huge issue
I am in Canada for work and havent had a problem before, usually i turn off mobile network just before the US canada boarder and will roam and only use my phone to text. Well I did the same thing and turned it off while it was using GPS which i have done before as well, but after i then realized the phone get saying it was "refreshing SIM card" and it would not pick up a signal. I tried reflashing, wiping, different rom and kernel, still nothing. I am wondering if my SIM took a crap or if there is something i am missing. Can anyone help?

[Q] LG 4X HD lost IMEI no network please help.

Hi, any help here would be greatly appreciated. My phone says no sim card and I have no network. Now that might not seem like a major problem but my phone has somehow lost its IMEI number.It has just gone! I have not changed the software it is just a standard phone. Any ideas how I get this IMEI back because without it my phone is useless? I have done all the usual factory resets but nothing works.

galaxy doing the same

My wife's samsung galaxy s gt 5380i has suddenly decided not to let her text/call. service state says out of service, mobile network state says disconnected.Her sim works in my iphone, and she has 3 bars showing of her EE signal. I've checked everything I can think of, but no joy. I cleaned the sim contacts, but apart from resetting the phone I'm stymied. My t-mobile sim didn't work in the galaxy either. When trying to call an error message says no mobile network available. I bought the phone a couple of months ago on ebay, it's immaculate and worked flawlessly until this morning. Please help, wife is not impressed...

[Q] Suddenly phone has lost complete mobile network

Hello there,
Guys really need your help. This is for my friend's phone;
Since last evening, his One has lost complete mobile connectivity. He says he didn't do anything out of the ordinary, nor did he drop the phone or anything.
Absolutely no network even after countless reboots. Once or twice the phone caught some network but only for a few minutes. Tried different SIM cards too. He had been using this phone flawlessly for 3 months, until yesterday.
He is an amateur at playing around with the phone, so I rooted the phone and installed a Lollipop based custom ROM hoping that would solve the issue, but no luck. Even reverted completely back to CM11 (44S) and then did a factory reset, still no coverage.
The phone is connecting to WiFi and seems to have no other issue at all. Only connecting to mobile network is the problem.
What do you guys think? What should I try to do now? Has anyone else encountered this issue, how did you fix it? I read a lot of posts here and on OnePlus Forums but haven't found an answer to this specific problem yet.
Edit-
I did try setting the correct APN, no luck

I have the same problem! I have tried everything: other modems, full wipes, back to 100% stock. The customer service keeps telling me to look at my APN settings...
Sometimes the phone is also stuck in airplane mode after rebooting.

Same here, I tried flashing a modem as well.
You can dial *#06# and see if your IMEI is visible, few users have suddenly lost it and hence no signal. For me the IMEI is present, still no signal

I had a similar issue yesterday after flashing CM12.1. Mobile data would completely cut out with no signal. I found if it toggled mobile data off and back on in settings it fixed it for the time being.

remove sim

Power off the phone, take your sim out and restart the phone without it, then power off the phone, insert the sim, and restart it with the sim in.
Or see if you can't borrow a friend's sim from another carrier.
Worth a shot.

I tried this multiple times, just tried it again but no luck. All other SIM cards don't work, even from different carriers (tried 3).
Also my APN settings sometimes show and sometimes they don't. When I try to save new ones, they don't show up.
My IMEI and baseband are visible and have not changed.

you've been trying

It might be worth it to wipe all the partitions individually from recovery, however first browse the forums to make sure you can do some sort of unbrick or restore the phone if it blows.
There may be data that is not being erased with lesser formats or factory reset. There were things stuck with my phone and it didn't resolve until I formatted all the partitions--except system, I think--after which it worked properly.
Do not just leap blindly in though, so you can be sure to get back out if stuck.
See #9 and #10 here:

Good luck.

You guys would be glad to know that the phone sprang back to life on it's own
Hadn't used it for about 2 days and was ready to take it to the service centre, thought I'd give it one last try, inserted SIM and voila. Full network and working smoothly since.

No service and mobile network. Really no fix? :(

Hii... Have been searching forum but seems like no one has the answear
Galaxy s7 european version. Phone worked perfectly for 4 month and then suddenly I lost mobile network and service Tried hard reset, network setting reset ect. nothing helps Put simcard in different phone - everything is ok. I red that this problem most likely can t be fixed by software... Is that true? Can I try something else to fix this? Whats the cause?
Thanks for your time

Still got an IMEI number when you call *#06# ?

Yes IMEI and SN pops up. What does it mean?

Call your carrier and ask them if it has been blocked

I guess tomorrow I will return the device. Bought it from official carrier. Doubt it s blocked. Strange that no one has solution to this problem yet because there are quite a few similar posts online. :/

Hey there. I have the same issue with Vodafone Sim card AUSTRALIA. phone just stopped working all of a sudden. Why would they blacklist it? Other sim cards work on the phone.

have you been able to resolve your issue? what was the fix?

Has anyone got any solution of this? It's been quite a long with this issue, I've searched a lot of topics but no solution.

I have the same problem. Phone don't see simcard somehow. Flashed latest original firmware works for 1 min. Pull out trace with sim insert it again works for 2 min and stops working. When it works for small amount of time i think IMEI its not blocked and almost sure its software issue. Yesterday flashed different roms and CSC and modems no luck. SimCard changed for new one. Have someone some clue what to do ? I can provide logs if needed.
After instaling Samsung Phone Info app from market gsm wen't back online. Probably a coincident but when I go to Hardware screen ther was no modem model. I tap it few times. Close apk run it again modem went show itself after a while GSM signal is back.
After reboot no signal again. Then i make magic with phone info apk again and signal want back.
This apo make some sort of device discovery and reset modem device / driver or this is pure luck.

Mobile data stopped working, APN is correct.

So just randomly yesterday the mobile data on my Honor 6x just cut out. I am just getting the service signal bars, no 3G, 4G icon. I've tried resetting APN and formatting the phone back to original spec, but I still have the same problem. I also ejected the SIM and reset it just for a shot, but nothing.
I am using a T-Mobile MVNO called TAG Mobile if it makes a difference. I can make calls and text fine, and wifi works as well. Just the mobile data acts like I have it turned off. I've checked to make sure all toggles are switched on for 4G but to no avail.
Oh and I am running Nougat 7.0 emui 5. I've been using it for a couple months with no issues till now.

Can you try another SIM card?! Just to know if the issue is from the phone

I don't have one available right now, but I will try to get a replacement SIM sent out to me. I don't really have anybody near that would let me borrow their SIM either.

Ok, once you do it, let me know the results

Weird, the network came back up randomly. Didn't even need to try a different SIM card. Thanks
