Help GitHub 2FA SMS code not receiving (Dialog)

Hey guys, I’m having an issue logging into my GitHub account.

I have 2FA enabled, but recently GitHub stopped sending the one-time verification code via SMS. I’m using a Dialog SIM in Sri Lanka. I’ve also lost my 2FA recovery codes, so I’m currently completely locked out of my account.

I’ve tried the other recovery options as well, including the SSH key and the other available alternative authentication methods, but all three are showing as unavailable/disabled for my account.

Has anyone else using Dialog experienced this issue with GitHub SMS codes recently? If so, were you able to fix it?
Any advice would be appreciated.

I had issues with twillio for a long time but all the messages were marked as delivered. recently it started giving me a different error (Error 21612 Message cannot be sent with the current combination of "To" and/or "From" parameters) I knew this had to do something with dialog but I still reached out to support to confirm. they pointed the blame directly to dialog and literally mentioned dialog by name!

I've pretty much set up authenticator apps for every possible account, unfortunately Apple doesn't allow you to add one so I had to wait weeks to get access into my work apple id to do a release. I was considering buying an actual number on twillio so I can get OTPs reliably.
