[Q] Flashed Bell Galaxy Tab No longer makes calls

I flash my Bell Galaxy tab using the steps outlined on this site and I was able to make and receive calls on my tab. starting two days ago I have not been able to make any outgoing calls. If I put my sim card into my cell phone I can make and receive calls. Is anyone else on the Bell network or any other network experiencing this? Any trouble shooting advice would be appreciated. Thanks

Cannot make / receive calls

I am unable to make or receive calls.
Whenever I try to make a call it says Mobile network not available. I get no signal from my carrier and I have to put *#*#4643#*#* change it back to GSM because for some reason it changes it to CDMA.
Whenever I receive a call same thing, lose all my signal and it aparanetly changes froim GSM to CDMA.
When I change it back to GSM I am able to browse and text with no problems but as stated above I cannot call.
If anyone has a solution or suggestion it would be greatly appreciated if you posted it here.
Thanks.

You should be asking your carrier.

They had no clue, just opened a case.

Unable to make/receive calls on S5, Data OK

I have a really frustrating problem with my S5 (900F) where I can't make or receive calls.
I initially assumed it was a bug in Cyanogenmod 14.1, as that's when I first noticed the problem; however today I have flashed stock firmware on the handset and the same problem persists. I can see a signal and if I disable WiFi I can see HSPA/3G data in the status bar and can browse, but if I try to make a call it immediately disconnects and I cannot receive calls either.
I have moved the SIM card to another phone and can make and receive calls there, so I am sure the SIM card is OK.
Any suggestions would be gratefully received!

VoLTE working when using Bluetooth but not when dialling directly on the phone

Hello,
I have got the odd situation with the SM-G950FD (Singapore non-branded XSP CSC) living in the UK and using the Vodafone UK network whereby I am unable to make VoLTE phone calls although I have got the VoLTE function enabled. I first thought it was because of the network, however I came to notice that I am able to use VoLTE to make phone calls when I make them from my car over Bluetooth. It is of course the same mobile phone, and I can confirm VoLTE use as the display continues to show 4G+ or 4G whilst on the phone instead of jumping to H+ or H.
It seems as if phone calls over Bluetooth must be triggering a different call initiation routine compared to making a phone call using the dialler on the phone itself. Has anyone encountered this before and has anyone an explanation for this? How can I fix this so that I can VoLTE phone calls from the phone directly as well?
Thanks
Wolfgang
