how to program the bot to understand if the sms doesn't arrive/numbers doesn't arrive or other problems, and to request a new number until the activation code is received
I use telephone verification through smspva.com which I ask how do I make 1 cell phone number repeat 4 times ??
BAS doesn't have a ready-made action for re-receiving SMS messages from a single number. You can implement this yourself using http requests to the service api.
