Be careful if you play around with the service menu on your Xperia Z Ultra, I just ran into a major issue (bug)?
I looked at the various options in the Service menu and one is about Radio Bands, but when you select it you have only 1 choice "USA Radio Bands".
Once selected, no way to change back to a different region and the phone simply gets disconnected from the Network with no way to re connect.
I'm currently going through a Factory Reset which seems to fix it.

You could also manually change the apn's rather than reset.

my atrix was fine today, but the signal suddenly disappeared from my carrier, and not make calls anymore. when I put my SIM card in another phone it recognizes the signal from my carrier and I can call. any ideas?
thanks
HELP!!!!
please
can be a problem in the GSM frequency?? Because I can find other carrier..
may have burned only one frequency?
how to check?
is possible to burn only the 2100 mhz frequence??
1. Try to search network in setting. Than choose your carrier..
2. Last way is to flash your atrix.
Power off / power on the phone. Double check your network and APN settings. Otherwise you might be looking at a factory data reset...

Last night at this time, 4 people I was with had full bars on AT&T, none of us could download/upload or make calls. 2 iphones, 2 android. Someone with a Verizon phone was fine.
Maybe your sim card broke?

Are you still without a signal?
Have you tried the factory reset yet?...
if you can, try someone elses sim card in your phone. Its a long shot but I have seen it work in the past. If it works, takes it out and then put yours in. Otherwise Flash SBF, or take it in for warranty replacement.
Just out of curiosity, have you installed any weird 3rd party apps recently?...

Might not explain the calling, but do you have anything in your APN list?
Settings -> Wireless & Networks -> Mobile Networks -> Access Point Names
If Access Point Names (APN) is Blank, then try manually adding yours in from this Master APN List Thread...

I'd just make a call, and then when I try to do another (some time later) had no more signal. the phone still works ... all turn out!
I'm the unluckiest person in the world!
So, while tweaking settings using *#*#4636#*#*, I've apparently disabled the MoPho's recognition of the Sprint network entirely, and now the phone continues to reset itself to GSM/UMTS only in Network settings, even after reboot, and even after i change the settings manually to "any CDMA" or "Sprint" after the fact.
4G however, works.
(shrugs)
This is a first for me, and a headscratcher. Definitely don't want to go the hard reset route. Any suggestions of what I should be looking for?
**Update** - Have somehow managed to get it to stop forcing itself to GSM/UMTS, but will now only set itself on Automatic, and will not allow me to set "Any CDMA" or "Sprint only". Clicking these options won't stick, and just reverts to Automatic.
Preferred network type in Phone Info is "GSM/CDMA auto (PRL). I've turned the radio off/on several times, and it still shows as searching for service.
Sigh..
**Update #2** - Factory data reset didn't do the trick; phone still can't locate network. I'm sure this has got to be an easy fix. Anybody?
**Update #3** - Sprint couldn't figure it out either, chalked it up to a bug, and swapped out the phone for a 3D since they didn't have any MoPho's in stock. Would still be curious to know if anyone else ever encountered this issue..

Just out of curiosity, coyld you try putting in a sim chip and see if your phone recognizes it? Also, what is your baseband?
Sent from my MB855 using xda premium
That is indeed a bug of the stock firmware. Only way to fix it is to sbf back to stock. Hopefully you are not on the latest OTA (235) as I believe you can not sbf that version (downgrade).
Did the same thing myself by tooling around in the debug menus.

Encountered the same issue when I selected USA band. Did several things and nothing good happened. Finally flashed 235_radio_only.sbf from peetr_ and it worked. GSM 3G is working and 4G seems ok but unable to test it as I am not in US.

This happens if your service provider is currently busy (in some case during a thunder storm) that means you can only make emergency dials....
since when u have that issue
have you done something befoure that could have made your phone state this
in the settings of your phone you can choose or search for service providers
settings -> wireless and network -> mobile network -> serviceprovider
also check the option above the mode (2g 3g )
Try rebooting,that works for me

I suggest that try turning on airplane mode for a few minutes and then turning it off. I know it seems basic, but it should reset your 3G. It may or may not work depending on the phone and the service provider.
I dont know how it is called in your language ive got a german rom and if i transalte it its called serviceprovider
just try a bit in the network menu

After you reach the APN's Screen.. press the menu button and click Reset to Default
Let me know after youve tried all the steps

I have an LG V30 with Sprint. Last week I noticed my phone wouldn't connect to LTE/4G network even in places where I know there is good service and other Sprint phones around me are fine. So right now it only connects to 3G and even then is mostly keeps going into roaming and won't go back to 3G until I toggle mobile connection on/off. I've tried just about everything I can do. Turned the phone on/off. Checked for updates. Toggled mobile network connection settings. Network settings reset. I even factory reset it and the problem persists. What very little I could find mention of this problem online mentions messing with the APN settings, but I'm not able to do that. For what it's worth the phone still connects to wifi just fine.
Any advice or help would be appreciated because I'm really lost here and it's becoming a real problem for my phone to barely connect to anything unless I'm on wifi.

If you're on stock, reset your SCRTN
Open dialer and type in the following code
##72786#
It will ask you if you're sure you want to reset, click on yes
The phone will restart and it will go through the activating process and you SHOULD have LTE now.

SCRTN is a wonderful thing, solved problems for me many times when I was on various Sprint MVNOs.
But it only works with CDMA networks and phones (Sprint & Verizon).
For stubborn network problems on other non-CDMA models and networks I found the engineering/service menu factory reset to be a life saver. In particular did it solve a lack of LTE connection after a "partial" T-Mobile SIM unlock. To be clear, it loses the SIM unlock, which allowed me to unlock anew (and fully this time). Just be aware of that.
1) Backup everything, as the phone will be wiped. If yours is a network unlocked carrier model, make sure you have an unlock code (or unlock approval if T-Mobile).
2) Remove your Google account to disable Android Device Reset Protection.
3) Dial *#546368#*932# (replace 932 with your model number). This should open the service menu. From there SVC Menu - Factory Reset (R&D Only).
This takes quite a bit longer than normal Factory Reset. Your phone is now TRULY back to factory state.
While I haven't experienced any problems after doing this, I cannot guarantee that it is risk free or that there are no side effects that I just haven't detected.
So I would ONLY do this as a last resort.
