Yes just call your service provider

Hello,
Yesterday I called my network operator since I was the only one in the office (compared to others with the same network operator) unable to receive calls.
The support made me receive a Network Configuration SMS, I applied it and immediatly the SIM started to turn on and off (see link):

As of now, my SIM works on other phones, other SIM (from same and different network operator) works on my phone. Looks like a configuration issue directly connected to my SIM/IMEI.
Tried to reset what I've been able to reset, and to reflash ROM. The only option left is to factory reset, but I'd not like to.
Is there a way to reset the SIM configuration? I am rooted if needed.
Thank you!
Got a MetroPCS LG Stylo 4. It was unlocked after 6 months of service. Tested on different network and it was working fine.
Recently it was sent to india as a gift. After inserting new sim, voice call is working fine. However data is not working not even 3g/2g. Tried different network. Same issue. Tried to network reset and even factory reset. Same issue.
Is it missing band problem? Or data is locked ? As long I know, phone can be network locked. But never seen data locked.
Any suggestion?
Phone's Android version is 8.1.0

Also ran across this phone dialer code that opens the Stylo 4s hidden menu...
277634#*#
With it you can Grant permissions to edit APN settings, edit the ant settings, enter into engineering mode, etc..
Also edit band settings..
I know I edited my APN settings removed xcap Added fota,Hipri
And so far seems as if my mobile data is running more smoothly and a little faster. I'm not sure if it's true about removing xcap removes the ability to tunnel your data to keep up with usage, I do know changing these three things has helped my data tremendously.
My network data can connect to 4g so phone calls and MMS, but the symbol shows no data, yet when I load webpages there is data transmitting. When on wifi the symbol changes to service data enabled, it seems to have glitched when off wifi. Have done hard reset of mobile data, used another Sim and my Sim works fine in other phones, only this Sim in my phone (some sort of Sim setting error?) How can I reset this? There is no data limits on the Sim, but it seems like it's incorrectly set, running pixelexperience
Just what the title says. My phone tells callers that I'm not accepting calls and when I attempt to make calls it simply refuses to do so or displayed a "call ended" message without ever dialing the other person. Everything else works fine and I can even make voice calls if I use duo mode instead of mobile. I can also receive calls if the caller uses duo mode.
Have been through everything except an actual reset. Unable to do that since the phone was a hand-me-down and I don't know the PIN. I've about reached the point where I do a hard reset manually but I hate to lose my data. Does anyone have anything I could try to either bypass or recover the PIN or something I could use to get mobile mode to work again?
Your sure you have service? If you do, do you have credit? Both of those would prevent you making calls. You can still use Duo if your on WiFi or you have a data only service. If you are showing that your connected to the network and you are certain you have minutes in your plan or credit available then you will need to call your network provider so they can see if there's any network issues preventing your calls. Check the network operators status page to see if there's issues in your area.

It appears that when using a Galaxy S9+ with ATT service the phone is unable to do VoLTE
The way that I was able to have internet on the phone and voice calling was to go into the APN and set the Network Mode to 3G/2G (auto connect)
That fixed it for me. Still pissed off that I can't use LTE but oh well it will work until I upgrade the phone.

Hello, I have an unlocked s9 that is going through a similar issue in not being able to make or receive calls. Can you let me know how you got the APN settings for 3G/2G? Going to APN settings I only see the nxgenphone setting open and active, which I heard was for LTE.
Also, can you let me know what setting it has to be in the 4636 mobile network settings in order to restore data? Thanks
Hi. I need some help when using the S918B/DS with a combination of a standard sim (voice/text/data) and an e-sim (data only). The e-sim is intended for use in the US while traveling, bought using an e-sim app. I've setup the phone to use physical sim 1 for calls and sms and the e-sim for data. An APN is provided for the e-sim which must also be used. Roaming is also enabled.
Initially the setup works out with both sim/e-sim appearing in roaming mode and the e-sim also with 4G icon using T-Mobile. However, when I turn mobile data usage off (to save data and battery) then later re-engage data then I am not able to gain access to data. The icons show (both) of the carriers in roaming mode and that's it. The only way to reengage data seems to be: go to manual network selection for the e-sim, disconnect from current carrier (T-Mobile), select a different carrier such as Verizon (where there is no access granted) and then re-connect back with T-Mobile. This must be done with data enabled, otherwise I still don't get any data access. This works but also means that I need to have data/4G on all the time and can not use it only when needed. Is there's anything I'm doing wrong or there are some settings which can be tweaked to bring back data without disconnecting/reconnecting for the esim ?

If you want to save battery while travelling, instead of disabling data, you might want to set your physical sim to 3G/2G mode only (since it only for a call). And just turn of slot 2 (eSIM) when not used. Or try to disable VoLTE on the eSIM.
Or just airplane it altogether if you doesnt really intend to receive a call anyway. (I normally do it during travelling, i only use my phone to snap picture in certain area, using wifi when in resto, cafe or shopping area, and then turning off airplane only when i need to navigate using map)
