Hello @Mike
Thanks for your query, and I understand the frustration on delay in registering your number for SMS. Please note, TCR registration is mandatory now for numbers to be registered with SMS service and be able to send texts within United States.
As there is not much info in this thread on this particular case, my only advise would be to contact RingCentral Support and ask them to get this escalated. Theres a direct dial number also provided in above support page.
If you have questions and want to talk to someone, you can reach our dedicated support team at 8559258622. We are available Monday to Friday, from 5 A.M. to 5 P.M., Pacific Standard Time.
Using support is the best route for questions pertaining to your account and numbers.
