Cannot send a text to specific number

[Android Central Question]

I was texting a number on my phone.i received a warning message about texting an unknown number and that "possible" rates may apply. I thought I was clicking accept and send; however, I can no longer text that number. Any suggestions on how to reverse or change permissions?

Welcome to Android Central! Is the number one of those 5 or 6 digit numbers you send short code SMS message to?

Yes, this is to a 6 digit number.

Which phone and which carrier are you using? You need to look for a "Premium SMS" or "Short Code SMS" option, either on the phone or on your wireless account website.

This is a Google Pixel 2 on AT&T.

Go to Settings>Apps, tap Advanced, then Special App Access, then Premium SMS Access. Make sure it's always allowed for the Messages app.

I have a Huawei p20 pro and I cannot send premium sms to 4 digit numbers. i have checked with my carrier and it is not blocked in my account. I have also allowed for premium sms in the settings. Any suggestions?
