Unable to send a message. Textlocal says "All numbers removed, unable to send this message". I use the country code as "+94". Your c# code is 100% work. I can get the OTP code from the control panel and verify it but only the error is from the "control.txtlocal.co.uk/send/" and cannot send the sms to "+94*********" . How can I fix this error.
