Why am I getting "Error Code 89501 Invalid phone number" when sending SMS to a valid phone number?
I think a picture is worth a thousand words.
I have tried every permutation of phone number I can think of.
In Thailand, where I bought the router and live, phone numbers are typically of the format 0XX-XXX-XXXX when dialing within the country. I tried that format and several others but keep getting blocked. How do I resolve this error please? It makes it hard when I don't know the error I'm making. Thanks.
