Can't receive SMS in Pakistan

It’s been almost 4 months, and we Pakistanis are unable to receive SMS codes, whether they are for already verified accounts or new ones. Is there a reason behind this, or is someone looking into the bug? I have a ton of operators and progress in my account already verified by ownership, and everything feels very useless because I can’t play due to just an SMS verification not working. I have tried with 5 different numbers.
