My unit says 'not registered to network' whenever i make a call but i can use the internet provided by my sim. This happens wheneve i access the flight mode and after turning it off i cant make any calls or texts.. but i have a strong signal and can use the net. I bought this already to samsung service ctr and they said that they changed the board. But the problem is still there. When i use my sim to other phone it works fine. And whenever i put it back to my s3, everything seems to be normal because i can make calls and texts already. Just dont access the flight mode.. havent tried if the problem will activate if i have a complete signal loss. Anyone one there with the same case? Pls help me with this one..

EDIT: Just tried a 3 sim card and it worked so I will get another T-Mobile Sim to see if the problem is a didgy sim card...strage as the sim works when I put it in a micro sim to sim adapter in another phone!?
Im in the UK, with T-Mobile and randomly cant send/recieve calls or texts
I called T-Mobile and they refreshed the network settings but I still cant call...they said it wasnt anything to do with network coverage as it was displaying i had signal, but in call settings > additional settings or call forwarding > voice call:
it says "Network or Sim error"
my sim works in another phone too so its not a dodgy sim...so it is 100% down to the phone that I cannot call or recieve calls or texts so not just call settings being messed up, problem surfaced 2 hours after flashing Foxhound 0.3 (but in those 2 hour calls/texts were working)
I have done hard reset, and facory reset, restored a backup...also flashed stock XXLF2, and also LF8 but all with no luck
My IMEI number is displayed in about phone, it is displaying full signal, and T-Mobile in the dropdown menu and im able to use my mobile data from T-Mobile so what is wrong, and how can I fix this?
Would be forever grateful to whoever can help me out...even if your not sure any ideas are welcome as my £500 phone is as good as bricked to me!
I will take it into T-Mobile to see if they will replace the handset under warranty but how do I go about making it seem it hasnt been rooted or flashed custom ROM, I know I need Triangle away but what order etc?
Thanks allot
Remove root apps .
Run Triangle Away
Flash original stock rom .

I have a Samsung S3 GT 19300.
Purchased in Hong Kong. Using China Unicom, and I have a monthly plan, fully paid up.
It is stock - I have not rooted it.
Suddenly, about 3 days ago, I started having problems with it connecting to the network. I ignored this issues because I was on vacation, and roaming ... so I thought it was due to the roaming.
I'm back home now, and I can not make any calls.
When I call out, the phone:
- sometimes doesn't connect to the network - the call doesn't go through at all
- sometimes dials the other end, but there is no sound between the two phones. When that happens, the phone connection lasts about 15 seconds, and then the Samsung phone shows the network as not available, with the circle with a slash through it, and says "Mobile
network not available".
I've rebooted many times.
I've took out the SIM card, and put it back in.
I've checked the firmware - and the firmware is current.
I've disabled JuiceDefender Ultimate
Strangely, I CAN send data thru the network, but can not receive or make calls.
I also found out that WHILE I CAN SEND / RECEIVE data (internet), FourSquare can not identify where I am...
Suggestions?
actually it seems like a problem with your network\sim card.
i'd try first to ask other users under the same network if they experience problem and replace the sim card
Backup Data factory reset ..
Try with a different sim card are the usual first steps .

I forgot to update my post.
I used a friend's SIM - which is on the same network (China Unicom) as my SIM card is ...
I had the exact same problems.
One of my friends tells me I should re-install a ROM ... What do you think?
QUESTIONS:
Should I try to root the phone?
I ask because (a) it's not yet
(b) I want to back it up, and understand Titanium Backup to be the best ... but that needs to be rooted.
FINALLY - how woulld you back it up? I hate losing data.
I have a huge DROPBOX account ... but don't see a great way to use that to back it up.
Thanks.
i've a similar problem but with sms..

If it's within guarantee then just take it back to the store. Sounds defective and rooting would void your warranty on a faulty device. You'd probably find that rooting and a custom rom would not help anyways.
My $0.02 is take it back to the store, but back up your setting to Samsung drive thing. It backs up message too.

I changed my SIM, I can't still browse on my cell network and I can make calls and whatever, but when someone calls me it goes straight to voice mail.
I tried restarting the phone... Everything worked fine yesterday...

Mobile network settings ???
Contact your network for settings .
Modem for your network ???
Cannot answer in full users posts no details of phone .
jje
Have you tried using the sim on a different handheld ?
also I would look for a setting that screens your incoming calls like blocking mode/phone settings.

Hey Guys,
Desperate lurker here saying First of all thanks for all the guides and everything that the devs and everyone that the community has done. I've search all of google and xda but i can't seem to figure out what's wrong with me Xperia Z2 .D6503
. T mobile carrier.
Basically since yesterday, I noticed that my phone couldn't receive or make any phone calls. but data internet, wifi internet and text messaging was working fine. Whenever people call me, i would just get a voicemail notice. At the time I was on the Marshmallow Existence rom. Ive done a lot of troubleshooting since then and still I can only make a call on GSM Mode.
Here's what i've done.
Wiped data and "reset" my phone on the Existence ROM - didn't work.
Wiped everything and flash Resurrection ROM - didn't work still.
Used someone else's sim card , couldn't receive calls either.
Use my sim card on a different phone - that one worked (SO IT'S NOT THE SIM CARD'S FAULT)
Placed back my sim card in the Z2 and reset flashed the stock rom from this page https://forum.xda-developers.com/xperia-z2/general/stock-t3355768
but that didn't work either.
I've also manually put the Tmobile APN.
Basically calls only work when changing it into GSM mode. but when i put LTE/WCDMA/GSM. Calls made under LTE/WCDMA/GSM Won't even make a dialtone when I make a cal. It basically just ends after a few seconds
I'm starting to think it might be a hardware issue because no matter which ROM i put, no matter how many factory resets and data wipes i've done. I can only make calls on GSM Mode.
Does anyone have any other ideas or should I just cry and buy a new phone.?
I suggest you to flash your phone with flashtool v0.9.18.6 and flash 291 ftf and wipe all
@whatsadophone
Have you try resetting APN for your SIM card when on your device?
thanks to everyone who tried to help. I don't know what happened. but after i tried putting the sim back in the Z2 to check my signals using Signal Spy, It suddenly can use LTE again. Only problem is since i installed that stock ROM, I lost my recovery mode and can't get it back. But i wont push my luck and just keep it like it is till i buy a new phone.

i have same problem any help pls?
try doing that signal spy solution by luck that I did in the post before that
Hi everyone,
I'm having an issue with my device since yesterday. I wanted to make calls but as soon as I try to call someone I was getting "couldn't connect message"
I thought that it's maybe something to do with the carrier but i restarted my device, and after the restart I saw that I now only have 4g, and not 4g+ displayed, and still got the couldn't connect message then trying to call anyone. When switching to 3g/2g in settings I was able to call, and I was also able to receive calls even when on 4g.
My internet is working fine over mobile data, there were no issues with it.
Also, VoLte icon is being displayed all the time, thatdidn't go away.
At some point yesterday I was able to make calls over 4g again, but never regained the 4g+ and a few calls dropped after 5-6 minutes of talking.
I tried a SIM card from a different provider, but still see just 4g, and not 4g+
So I am not sure what could be the issue anymore.. Did anyone maybe encounter something similar after this last update? Maybe that's the issue. I don't know if I should consider suspecting a hardware issue because internet works fine all the time.
Clear system cache, clear sim toolkit data, and do a network reset.
See if that gets it...

Thanks for the tip!
I actually tried doing all of that and nothing was helping.
At the end I changed the CSC back to my stock one (TOP) and 4g+ is back.
I have no idea why this happened because I was using BTE csc for months and everything was ok. I'm just glad that it's not a hardware issue.
