When trying to send SMS to short code recipients like 567676, 56161, etc. from Samsung Galaxy Note8, I got the following error message:
Failed to send message. Review message and try again.
I've tried entering the correct SMSC number, allowing premium access, nothing has worked. I tried the SIM in another phone., I couldn't send it from there too.
I'm able to send SMS to normal phone numbers.
How to fix this?
