Maybe bad connection on your sim card?
Try removing the SIM card and put it back in, and then boot the phone.

done that, doesn't help

Im getting hte same issue. The 4.0.2 update came through, rebooted the phone. SIM not found, press to reboot....
Rebooted, SIM still not working. remove SIM and replace. Still not working. replaced with another SIM. Still not working.
Was working fine prior to the 4.0.2 update. This is on a 1 month old phone that has never been rooted. It is still as stock as it comes out of the box... And i want to test it more before i start boxing it up to send it back...

Have you tried leaving the battery out for a bit, then trying powering it up again?

Here is where it gets weird. I tried 2 other sim cards as well as my own. none of them worked. put my sim card back in and tried again, still not working. turned it off over night. went to Vodafone and asked if i could try a new SIM in the phone. still not working. put my TPG/Optus sim in and it started working. got a new SIM from Voda, transfered all the account info to the new card, waited an hour and tried it again and now it works :/
Dont know what caused it to stop working and dont know what caused it to start working again :/ im going to throw the word "Vodafone" in there as the cause because people will just nod their head and say... "yep, that was probably it..."

I have the same issue with AT&T....the phone does recognize the SIM, APN and all...but no signal. Just once in a while it gets registered on teh network, but for one minute or so...I don't know what to do

Same issue here, after a reboot my phone does not recognize my sim at all. no signal at all. tried a different sim, nothing, bought a new sim but nothing again, returned to stock, everything, but still nothing....no remedy yet....

No Connection to Carrier, please help!

Ok, so I updated my s3 to 4.1.1 but after a week of using the update, I still hadn't seen any sign of the expandable notification options. So I decided to re-install the update by flashing via Odin, which I did. After the flash, the expandable notifications still weren't available, so I instead flashed the stock firmware, hoping to update from stock and see if the problem was fixed. Unfortunately when I rebooted after the stock install, my phone would no longer connect to data, or even to the network period. I can't text, make calls, or connect to data. It shows full bars but when I try to do anything it tells me the network is unavailable.
I tried a lot of options for fixing it:
-I checked all my network settings. Data was on, I switched into and out of airplane mode, no luck.
-I tried to set my network operator by manually selecting tmobile. No luck.
-I tried re-entering T-Mobile's APN settings. No luck.
-I tried to restore from a backup I made of my 4.1.1 when it was first updated. No luck.
-I tried flashing multiple versions of stock firmware, as well as cm10. No luck.
-I checked my IMEI, it's correct.
-I flashed a few different modems. No luck.
I've run out of ideas and I can't find any other ideas in the forums. The closest I have come to getting a fix was during one instance when I was flashing stock again, I cleared my cache, dalvik cache, and did a factory reset as well as formatting my internal storage. When it did the first boot it had service for about thirty seconds. I was able to receive a few waiting text messages, and I had edge data for the remainder of the 30 second or so period. Then I lost data again. Every time I boot a notification ticks on my status bar that says "Restricted Access Changed" and before I can pull down and tap it, the notification is gone. When I try to set a Network Operator, it says something along the lines of "Unable to connect, not registered on the network." I'm stumped.
Has anybody else had this problem, and does anybody know how to fix it?

Just a guess, but perhaps T-Mobile has blocked your IMEI? Did you buy the phone off of someone or straight from T-Mobile?
Did you ever report it lost or stolen?
Only thing I can think of given your scenario.

I bought it through Costco as an authorized upgrade offer by T-Mobile. I can't imagine any reason why my IMEI would be blocked. I went to the t-mobile store yesterday and they told me that it should be working and that I should take it back to Costco and see if they can do anything for me in terms of replacement.

Problem Solved!
Apparently it was because when I got my phone they didn't give me the upgraded sim, they just cut my current one to fit the microsim slot. Go figure. This could have been solved by tmobile last night if the guy hadn't refused to help me just because I had rom manager installed on my phone. Just because I have a root program installed on my phone doesn't mean my phone got messed up playing around with root. Anyways, i updated my sim card through tmobile's phone service and I'm a happy camper now!

Mobile Network Not Available

Hey guys,
This may be a silly question, but I can't seem to find a solution.
I just flashed PAC-ROM 4.3 using CWM, and everything seems to be working great.
Than I realized I didn't have a mobile network signal, so I tried placing a call and it said "No mobile network detected".
How can I enable mobile network, cause it's not even in the settings no more?

I have the exact same problem, anyone with any kind of possible solution? Here's what I tried already:
1. Removed both battery/SIM for a minute or more then rebooted. (Also made sure that 2G was off)
2. Called a Koodo tech guy who updated the SIM.
3. Went in store to try and put my SIM in a different phone, SIM worked fine.
4. Lady tried installing a different SIM card (her own), still same problem. Tried a brand new one, still not working.
5. Backed up my pictures and factory reset the phone. Same problem.
6. Took SIM out, and the phone does recognize there is not a SIM card and now the phone gives me the NO SIM CARD message at unlock screen.
7. Updated to 4.3 - Nothing changes.
8. Browsed the internet for hours then cried myself to sleep, hoping someone would help me out eventually.

I had the same problem with revolt ROM. I flashed baseband and wiped all data but nothing changed...
I flash a factory image and it worked
Sorry for my bad english

1. Try changing radio.
2. Get a new phone. It seems to me that something broke in hardware.

Moto Z Play not showing VoLTE for specific JIO Sim

Hello Everyone,
I need some help regarding the network issues for Moto Z Play.
I started this thread because after doing a lot of solutions, resets and still it wasn't successful.
So here's the story -
Two days ago my brother gave me the phone which was in excellent condition (VoLTE working, Battery Performance, etc.) working on Android 7.0.
Then he did a reset on the phone from Settings so I can use it.
When I inserted my SIM Cards in the phone, I got network and everything and immediately I received an Update for Nougat 7.1.1. I installed the update and then when the phone booted, I did the setup and everything. But l wasn't able to get VoLTE on my phone. There was no Enhanced LTE Mode option in Settings. I thought it was something temporary and maybe after sometime I will be automatically resolved but it didn't.
The next day I started researching over the internet and found clearing the cache or data of settings or hard reset from recovery/settings will do and I did it but none of the solutions worked. Then I thought it was the SIM problem but it wasn't. I inserted the same Jio SIM from my phone into another VoLTE phone and it was working. I also tried another Jio SIM in Moto and it was showing VoLTE and everything was working perfect. Also I inserted my idea SIM (which was in SIM2 slot) in SIM 1 and it was not showing even 4G range (Just 3G) (The idea SIM is also 4G).
I tried everything - Swapping SIM cards, resetting the phone, Clearing cache, etc. I don't know why this has happened as my brother was using the same carrier sim in same slots (SIM1 - Jio|SIM2- Idea).
I also called the JIO care and they took the complaint and they told me they would look forward to it in 48 hours.
Also, my bootloader is locked and can I flash original stock firmware? (I guess that's only thing left I haven't tried) If so, please provide the link and guide to flash the firmware.
If Anyone has a solution please help me, I am in big trouble.

Get a new sim card for your number. Don't ask why. But this will work, trust me.

Thanks man, I was too thinking of that and went to JIO store. They had a server error and will be back available in 4-5 days. Will then post with new SIM results.
