Mobile Network Not Available

has anyone had this issue where it says "Mobile Network Not Available". I was running CleanRom 4.5 and installed the 4.5 keyboard and clock and all of a sudden I lost my network connection. what is weird is the 4G works fine. I just can't receive or make calls/text messages. Does anyone have any idea what may be the problem? I've returned my phone to stock, cause I'm thinking I'm going to have to take it back to Verizon. Just wondering if maybe anyone knew a fix for this.

That's weird. I'm running 4.5, and I have not seen that. Is data back now?

Yeah, i dont know what caused it to happen. I didn't even really notice it wasn't working, cause I never lost data. i've always had 4G signal. i just can't make phone calls or send texts. at one point it did say mobile network not available, but now it just doesn't make calls at all. the screen looks like its making the call, but you do not hear any dial tone or anything. For sure it was working yesterday because i was on a four hour call last night. Just stopped out of nowhere today.

I had the same issue the other day. Did you backup your IMEI/MEID info? Check and see if they are still there in about phone, also check your ERI and if your network is listed.

I just got back from the Verizon store after spending 2 hours there. It did seem like it was an IMEI issue. They mentioned my phone having a different number than what was on the phone itself and they could find no way to correct it. The verizon tech support that they called were insisting that it was a network issue and not a phone issue, so they opened a trouble ticket to try and resolve that. they said 24-72 hours to get it resolved. luckily, the store clerks and managers thought support was full of it, so they decided to overnight me a replacement phone anyways just in case, even though they were told not to. so hopefully the new phone fixes the issue. I'm just glad that they helped me out because I didn't buy warranty or anything on the phone so they probably could have flat out denied me. Fingers crossed that all is good in a couple of days
I did back up my IMEI the first time I rooted the phone, but since they're helping me out, I'm just going to wait for the new phone and hope that that fixes it.

I had the exact same issue I just call this number
*2767*3855#
If that doesn't work flash back to stock lock the phone do the number again

Take out your battery and look for the IMEI number that is listed underneath it. Write it down. Then boot your phone back up and go to settings, about phone, status, and make sure that the number your wrote down matches the IMEI number on the phone. If it doesn't, then you'll need to restore your IMEI and probably repair your ERI.
Read this thread. It explains how to repair them both:

I had this exact same problem yesterday. I noticed it occurred when I left a 4G area. I couldn't connect to the network anymore and it prompted me to switch to global mode. My IMEI number on the back of my phone matched the number in the status too.
The way I fixed it was by doing an nvrestore in terminal emulator. You need to have a backup in place in order to do this. I believe you can find more about it in the IMEI thread in android development. It should be the first step and they'll probably be able to help you more there. http://forum.xda-developers.com/showthread.php?t=1852255
Also, I'm running Clean Rom 4.5, stock kernel, and the vrlg7 radio.

Thanks - will try this out and let you know if any success.

4g works... That's all. Help getting calls and texts please.

My phone was on clean rom 5.0, Loved it. Everything worked great for 2 months. 3 days ago I flashed CM10. Worked alright. Then flashed MIUI (pre-most recent update). Also worked fine except for some screen flickering. Decided to go back to stock. Did a nandroid restore and when it was finished I had no data or bars period. Restarted the phone to no avail. Called Verizon. They assumed my simm card was fried. Then I went and got a new simm card. They tried to activate it to no avail. After changing my PRL from 00000 to 15154 they were able to get 4g on my phone. It's a little slow but it works. Still no calls and text.
My phone number is 0000004548. Any ideas on fixing this?
http://forum.xda-developers.com/showthread.php?p=31051731
This is my next option. Will it help? Come on xda, I have faith you can save me! Thanks all!

Still no luck
I completed the guide in the first post. No dice. I got everything sorted out, My phone number is now correct and all but... I cannot get signal still and I cannot boot into recovery. Weird. Any advice would be great! I'm sure others are in my spot.

Is your imei intact? I also had this problem prior to flashing miui. What I did was go back to completely stock, there is a guide somewhere here, make sure you backup all your data. Once you've boot up to stock, you have to dial the re provision code which is *2767*3855# , it will wipe all your data I believe, then reboot it should work then. After that just reroot unlock flash roms. I hope it works for you. If you've lost your imei you have to do something else which a guide is written on here, but I'm pretty sure you haven't lost your imei.

Yes, first thing to do is to check if your IMEI is intact. Also check your ERI (it should be set to 5).
Just a heads up, the re-provision code @Watoy mentioned only works on early build stock ICS. You can use the code in Root66, so my advice is to Odin back to Root66, which is available for download from this thread:
http://forum.xda-developers.com/showthread.php?t=1762204
If your IMEI and/or ERI is not intact, the following tool and guide will bring you back to life. You will also need to be on stock ICS for this, and I again recommend Root66 because many users need to perform the re-provision code after performing all of the steps in this guide to complete the process:
http://forum.xda-developers.com/showthread.php?t=1867442

I'm attempting everything you two mentioned right now. I'll let you know how it turned out. I have already done each of these things but this time I'll follow the order (if that makes sense...)
Network - Unknown
Signal - -95 dBm 2 asu
Mobile net type - 1xRTT:6
in service
roaming
disconnected
phone # - 0000004548
Min 0000004548
PRL - 1
ERI - 5
IMEI - 990002068950862
IMEISV - 00
Definitely boot loops for days after flashing stock.vzw_root66.tar Any other ideas?

Alright. Flashed stock.vzw_root66.tar and it bootlooped. I pulled the battery after ten minutes and went into recovery and f/d reset. Network unknown. Signal strength and network type is the same. now service state says in service. Mobile network state still disconnected. PRL changed to 15173. phone number is correct. MIN is 3194421067. ERI is still 5. MEID now reads DEC: 256691456608999046 HEX: 0x99000206895086. IP address is now unavailable.
Can you read all that?
Okay I got the reprovision number to work. Going through that now.
I FIXED IT, Thanks to ya'll.

Now use the dialer code listed earlier

I don't know if I should make a new thread about this? What do ya'll think?
Flashed stock.vzw_root66.tar. Bootlooped, pulled battery, factory /data reset in recovery.
Then dialed the *2767*blah blah. And tada. Everything works.
Post links so I can buy ya'll beers!

Dead serious. I just dropped it 2 feet onto carpet and there is a small crack above the menu key. Phone is a goner. Black screen and all. I still claim this endeavor as worth it, hopefully it helps others out. Off to buy a $40 droid x on craigslist. ugh

A quick look at the thread you linked to, it looks like you need to be back on an ICS ROM (at least for TW) to use the factory reset/reprovision(?) code, after repairing the IMEI.
The key to make it all work together seems to be this order: http://forum.xda-developers.com/showpost.php?p=33609227&postcount=160

You didn't miss anything, you just need to do that re-provision code. Flash back to this, do the re-provision, and you will be back to normal. No other way about it unfortunately.

This just saved me! Thanks a ton, sorry about your phone though. Just fixing the IMEI and ERI didn't work for me, I had to reset with the code

Same Issues
I suffered from no sms and no calls, reflashed root_66 tar from odin, then reprovisioned with *2767*3855# and i got sms and calls back but was stuck on roaming with it always trying to get me to install dual clocks, i figured it was a sim card issue as my imei was proper and everything was as stock, i took it to local Verizon, they installed new SIM for free, but it did not fix the issue. With a few kind words and pointing out the extras i spent on accesories, i ended up getting into the Note II. Keep In Mind i was still in my 30 day worry free, but for the SIM card it didnt matter, he did not look up that info till he told me he was going to replace my device if the SIM didnt take. I STRONGLY advise to approach them with kindness, i also informed them it happened when i kept toggling connection when transfering media thru the usb cable, i figured the heat and constant connect/disconnect fried the sim, they never asked if i tried to download any off market apps or anything along the MOD lines. Hope this helps anybody that may need it.. i did follow step 5 of the guide everyone references about rooting jellybean(root,custom recovery,stock), sorry new to forums and havnt figured out the linking yet, but once on the stock file with this name,( COMBINATION_I535VRBLK3_I535VZWBLK3_381038_REV09_user_low_ship.tar)everything read stock except my binary count, but i heard this is only an issue if sending to samsung as verizon reps are unaware of binary counts and odin and stuff related

Nexus 5 - No service....help please

Ok this is a weird one.
Phone was working ok yesterday throughout the day. In the evening I noticed I had no signal so I rebooted the phone but still nothing.
Checked my operators (O2) website and it said there was a fault with my local mast. Ok I thought...should be ok tomorrow.
Woke up in the morning, still no signal. Mast still showing a fault. So I travelled to work 6 miles away, but still nothing. My local mast in now working again, as is the one near my work, but still can't get any service.
Factory reset to no avail. Tried another sim card of a friends in my phone but still nothing. If I try to search operators it brings back the usual UK list, but if I try to register on the network I get 'Currently unavailable. Please try again later' (or words to that affect).
Im starting to think it's the radio in my phone. It's just strange that it coincided with the fault on my local mast.
I also have the issue that I slightly cracked my screen about 2 month ago, so now I apparently have voided the warranty on the phone despite it being less than 6 months old.
Anyone have any suggestions? Or is my phone screwed?
N.B. I should probably add that I am on OTA Android 5.0, have been for a few weeks now....and my sim card works ok in another phone.

Have you tried reflashing a radio .img using fastboot while in the bootloader? Or maybe the cell tower is still having issues.

The warranty doesn't cover non-manufacturing defects. I don't think they'll replace it under warranty if its physical damage/wear and tear that didn't occur during the manufacturing process.
Also, Google's "policy" of a one-time replacement of a cracked screen for US customers is NOT part of any sort of warranty, more of a "why not since we have so many spares from people RMAing because of silly things like speaker hole size, light bleed and loose power buttons". Google has the right to refuse if they don't feel like it regarding this "policy".

Do I have to have rooted to reflash the radio ?
The mast isn't having issues anymore according to my operator, but I'm in a different location now anyway so am on a different mast.
Unfortunately I'm in the UK so don't qualify for the cracked screen replacement as I looked at that option when I first did it.
Does the fact that I can see the list of mobile networks in settings mean I don't have a hardware fault with the radio / modem?

1 more thing I have just noticed. I was going to check my IMEI to see if it was somehow blocked. However, when I go into Settings > About Phone > Status, the IMEI shows as 0.
When I dial *#06# the IMEI also shows as 0.
I'm guessing that's not right and it's the reason I can't connect to any network ?

That's probably your issue.
Flash a radio and cache.img from factory images.
If that doesn't work and you don't have an EFS backup then there's not much you can do.

It's happened a couple times to people, mostly with cache derps. Either that, or they restored an EFS backup from a device with a different IMEI (which damages it permanently unless you had an EFS backup of the intended IMEI), flashed something not meant for their device, or something else that damages it.

I have a similar problem. No service, sort of stuck in airplane mode. Radio is off and I can't turn it on. It all started after I upgraded to 5.1.
I've tried downgrading to 4.4.4, cm11, flashed different radios etc... I do see IMEI though but my radio is unresponsive. When I manually try to save APN settings nothing happens, they don't get saved.

I had the same issue as the OP - a tower was down in my area, and even after it was restored my phone got stuck with no mobile date service (although the odd thing is, voice and texts worked fine, just not mobile internet).
A factory reset was the only thing that fixed it.

S6 (G920F International Version) No Network Selection/NO SIM DETECTED

Hello,
A friend of mine has a new S6 which is unlocked to work with any network/sim. The phone was working perfectly for a few months.
Now for some reason, it gives the message that no sim detected. Signal bars show up. But no connectivity.
The option in settings Select Network Operator is gone, and no longer there.
I have tried re-flashing stock 5.1.1 ROM and still the same problem. Tried flashing previous 2 modems and got the same error, so flashed back to current one.
Current Baseband: G920FXXU3QOKN
Kernel Version: 3.10.61-5896496 [email protected]#1
Another thing to note is that the phone shows signal bars perfectly, even though there is the no sim message. Also, on removing and re-inserting the sim, it reads the sim and asks to reboot, after which it comes to the same situation.
Any help would be appreciated.
Thanks,

I have same issue, and would gladly fix it. :/

IMEI was reset to 350000000006, then some Russian guy fixed it with Z3X box, SIM was able to register, but reception was awfull (lots of missed incoming calls, etc.). then I flashed some more fw and modem to check wheter it would fix dropping signal issues, and then it started not to recognize SIM.
So to sumarize, IMEI (with my EFS, not @tazaga one) is fine in the IMEI info, in SIM info everything is unknown, and mobile networks menu is missing from settings.
I changed SIM for a new one, just to be sure, and is detected only when inserted/removed, then phone wants to restart to enable mobile networks, but after restart, nothing changes.
Serial number was changed, but I corrected it in a file in EFS folder.

Ya by the sounds of it something is still funky in your efs folder

As far as my problem is concerned, the IMEI and the SERIAL number both match the inside and outside. So its not that.
Any other suggestions as to what it could be? Or how to fix?

Flash stock with smart switch but before that make efs backup ( in case things goes down )

Already tried smart switch and also Odin to flash stock. Neither worked.
Would flashing an EFS backup from another phone with the exact same model work?

well I tried to flash @tazaga efs, IMEI gets unknown right after that, but managed to boot up without custom kernel after Smart Switch initialization.
Beside that nothing changed, still no SIM and no mobile networks menu, and sadly couple hours later, phone went to a boot loop.
I took it to some 3dr party repair shop, without restoring original efs and bootable fw/kernel, they said they cannot repair it, but will give phone to some "software specialist" who may be (I seriously doubt it, according to my prevoius experience with 3rd party sw specialists (last time it took me half a day to reach the state phone was in when I deliverd it to them)) able to fix it with a 50-50% chance of fixing it.

I understand that, but I kinda doubt that no SIM issue is somehow tied to IMEI
Because with my efs backup (which was made after Z3X repair) IMEI is fine, but still no SIM.
I was kinda hoping that it could be something else in the EFS folder that made SIM undetectable, but even with your efs backup (thank you once again for it) SIM is not detected, so I guess that no SIM issue is tied to something else that is corrupted, or accidentally switched off.
I just dont know what could it be, because I was messing with service mode and codes unknown to me to try fix poor reception, so god knows what I did to put the phone in state in which is now.
Perhaps I am just trying to provide every information possible, and exchange it with others who have same issue, or more experience than me, so we can together figure out what has caused this and how to fix it, and help others who will have same issue in the future (and obviously I am not the only one with such issue).
And as I pointed out 3rd party repair shops didnt proove quite usefull (perhaps their services are just flashing/rooting/unlocking, but I can do that by myself without paying someone else to do it)
We will see next week, what will guys from repair shop say, but I am not very optimistic about that.
If nothing else I can still give some money to that Russian guy with Z3X, who fixed IMEI in the first place, I guess he won`t mind
And sorry for the OT.

This problem still going on with exact answer..
I also have same issue on customer's phone.
I've tried backup cert and efs then repair efs (on octoplus).
after repairing efs, it changed IMEI to 3500...006 but still no sim card.
Seems like I can't fix even with Octoplus.
Hopefully someone finds way to fix this asap ;(

So apparently EFS and stock firmware has been ruled out. I already tried different modems using Odin.
Anyone have any other ideas? I mean other than the Sim Not Found thing, I can't even see the network selection option in settings, and using *#*#4636#*#* only gives an error that not registered on network.

well @ariza27 made similar fix for S3...

I guess there is nothing to do but wait for developers to create something for S6.

If I am understanding that problem correctly, the SIM/Network problem in the S3 came from the SN or IMEI changing due to upgrade or flashing.
This phone has the same SN/IMEI inside and outside. And its not just refusing to register the SIM, the network options have disappeared as well. I had hoped flashing stock would help, but no cigar.
One thing though, would completely erasing the data partition, and wiping the entire firmware, and then installing stock or even another ROM help? Because even when flashing through odin, it preserved the data for some reason.

Can someone send me their EFS backup for G920F on v.5.1.1 Stock with baseband/modem G920FXXU3QOKN?
I don;t know if those things affect EFS or not, just want to be on the safe side. I want to try comparing the backup from my phone and one other and then try and restore using the 2nd one.
As far as the IMEI and SN changing goes, I am looking into how to prevent that in the first place on in the even that it happens to restore it.
Any help is appreciated.

Bump! Anyone?

Your imei number has been blocked/blacklisted because of a reason like lost or stolen phone, reported by previous owner, the only way to fix it is to replace the motherboard of the same model from a supplier on aliexpress website, there price is about $350.00 Australian dollars thats including EMS express postage,you get it around 4 or 5 working days, dont waste your money or time on anything else it won't work, I had same problem, now after new motherboard my galaxy s6 edge is working fine, expensive though.

Any luck with this issue?

The phone was purchased new. And Already spoken with both Samsung and Vodaphone regarding this and they say the IMEI and the phone are clear. The phone is in another country from that of purchase, but since there is no country lock or phone lock, this is not the problem.
And no such luck yet.

Network issues

Hi guys,
I'm new to XDA and wanted to thank everyone for all the great posts.
I have purchased a Mate 9 MHA-AL00 recently. It has been a great phone to play around with and figure out all the great features it has.
I have been facing some trouble with regards to connecting it to my carrier. I have tried inserting my sim card and I only get the "emergency call only" prompt.
I have visited my carrier story to ensure that network settings are correct and they have verified that this is not the issue. I have visited a cell phone repair shop and they were not able to assist either.
The weird part of this is that the phone picks up my phone number and carrier information but does not connect. I have tried 3 other carrier sims and haven't had any luck either.
I did however get a little break the other day. I placed two different carrier sims in my phone at the same time. Both carriers worked! No data, just phone calls were working. After about 5 minutes, one carrier dropped. I removed the sim for the dropped carrier and the second carrier dropped as well. Could not get them to reconnect.
On a couple of occasions, a 3G sim card has worked as the only sim. It works for 5 minutes and then drops.
I've tried to research and look around to see if anyone has any similar issues and have not had any luck. I'm quite new to android phones and by no means a cell phone expert.
The phone was purchased in Malaysia and I do not have the option of returning or exchanging.
Thanks guys. I look forward to your expertise.

That's definitely not normal. Try reflashing.
Was this a brand new unit? If not you might have gotten yourself a stolen unit with a barred IMEI.

Was not in the box. Anyway around a barred imei?

Yes try re flashing ur phone.
Download this file it is Al00 firmware,exctract the rar and copy the exctracted folder to an sd card,turn off ur phone and press 3 buttons,power volume up and down till the phone start updating.
This will wipe everything so make sure to backup first.
It is an old firmware but you can update to latest firmware in system update.
Good luck

Follow gm007's instructions and try reflashing it. If that doesn't sort it I'm afraid you're stuck. Get in touch with the seller if that's an option, you might need to ship it back to the country of origin to have it looked at by Huawei. Then again if you're in possession of stolen goods (you implied that's a possibility) you can forget that.
Bypassing IMEI locks is illegal and discussing it is against XDA's TOS.
