When I first setup my mi mix 3, I had wifi calling enabled and working on Google Fi and T-Mobile. For some reason, wifi calling has vanished. I've flashed multiple roms(stock and custom) with no lick of restoring it.
Any ideas?
Try this Code:

I received "connection problem or invalid MMI code" error.
Do you use 2 Sims? If yes, deactivate the second and try again

Bump,
Please need help
I just sold my i9003 to my friend. When he inserts his airtel sim or any other sim and give a network search and click on airtel (or corresponding network) he gets the error message 'Can't connect to this network right now. Try again later' several times in two days we have tried and still get the same error.
Ref: My original sim in the phone :Airtel
My rom : cm 10.1 alpha 9 (Dhiru)
I have tried reinstaling the Rom to no avail. Please note that this problem is only recent. I have been using this rom (cm10.1 a9) ever since its release with no issues, the issue occured only when I changed to a different sim. However, it still works on my sim.

Hi guys
So I have the 23rd december version of Cataclysm installed, ElementalX kernel latest and I also flashed the 5.0.1 nexus 5 radio. Everything was working smooth for a day or 2 (no problems at all, I love Cataclysm). When I was on the train yesterday my connection (2g, 3g, 4g, everything) fell away as usual on Belgian trains in some areas, but it didn't come back... Now I'm stuck with a nexus that only has wifi... Does anyone know what to do? I have never seen this before so I'm clueless
I have tried installing other radio's. With the KitKat one, it didn't even find my SIM-card(no PIN login whatsoever)(this is also not a SIM related issue because I tried other phones). When I flashed the one from 5.0.1 back, it was the same issue all over again. I tried using * # * # 4 6 3 6 # * # * but it says my radio is off, gprs service too. network type unknown...When I try to turn the radio on via the button in the menu, nothing happens...
I did a full wipe in TWRP, installed cataclysm and elementalX again and again:nothing...
Do you have an IMEI in Settings > About Phone > Status, or is incorrectly at 0?

check if phone can make emergency calls, then you will know if there's radio or sim card detecting problem

Does it register the SIM? Have you tried putting your SIM in a friend's phone/putting your friend's SIM in your phone?

It does register the SIM. When i put it in another phone, it works just fine
Yesterday, my IMEI and smallband were gone. I did a full restore to stock (root gone and locked). The IMEI and the smallband are back but the problem is not.
When I do the *#*#4636#*#*, it says the radio is off... I cannot push the button to turn it on, nothing happens.
thanks for the help so far, when the problem isn't resolved by tuesday I'm RMA'ing the device. but I'd rather not

If the SIM is fine and it doesn't work on stock, then its likely a hardware issue, so I'd just go with the RMA.
Hi guys, I have been trying to get the MI 4c working with the data but still with troubles. I have restored to stock 2 times ( a long nightmare getting locked by the way) and still without getting the Data working. I can call and use internet with WIFI but not by itself.
Anyone can give a hand?
Trying with different bands in the menu of *#*#4636#*#* without a happy end.
THANKS A LOT
trying this guide about Restoring IMEI DIDN´T work!!!

Are you using 2 Sims? Have you tried manually adding the apn details?

I am using only 1 SIM, and YES I have tried to put APN manual.
Does the *#06# gives you an IMEI number (or 2...).
If not, what happen to loose it? You should start by explaining that.

It is giving me 2 IMEI NUMBERS but in Settings, About Phone and Status doesnt show my mobile number.
AFTER RESTORE TO LATEST MIUI I can use DATA 4g but I want to use Cyanogenmod instead, lets see.

That's not important.
So in the CM, there is just a problem with APN.
Post what are they maybe someone from your country could help....
After restore Stock rom MIUI 6.1.7, unblocked with fastboot oem unlock and flashing twrp and CM 14.1 I got 4g working I went to something about SIM CARD activate, and removing all APN and putting my APN manually. I did it before but didn't work .But after all it interrupts also WIFI after a few minutes I dont understand why.
Hi, i've a problem with my htc one e8 sprint.
it's unlocked and until two days ago all works good.
Sunday morning i 'found' the message "Invalid SIM card. Contact Customer Care" and the GSM network works only for emergency call.
If i remove the sim the "no sim found" error was raised but when i insert it again the error change in "invalid sim card".
I try the SIM in another phone and it works. I also try another working sim in this phone but the same error is raised.
I try to flash another old backup images via TWRP (android 5 and android 4.4) but the error was the same.
i check the IMEI with imei.info app and it seems to be unlocked.
when i change the network Type in screen "Telephone Info" (reachable via *#*#4636#*#* code in dialer) nothing happens.
now i'm using the ViperOneM8 rom and it works good for 4 months.
any ideas?
may be the radio hardware defective?
thanks for all your help.
have a nice day.

hi,
the SIM seems to be locked again. the hardware is OK.
i solve the problem with the following steps:
1) backup current rom via TWRP.
2) reinstall the RUU version 2.32.651.11.
3) Unlock the sim again with the method in the thread named:
Getting SPC Unlocking SIM M9 SPRINT [NV]
found at :
http://forum.xda-developers.com/sprint-one-m9/general/nv-unlock-sim-t3314755
it works with my HTC ONE E8 Sprint!
4) Flash again TWRP 3.0 and supersu via WinDroid 3.1
5) restore previous backup made in step 1
The only mystery is :
Why the SIM locks 'alone in the night' without 'strange' operations like flash kernel or some other apps?
hope this can help someone.
have a nice day.
