For Example –

If you’re sending an SMS message to a San Francisco number beginning with 415:

  • If a phone number with prefix 415 is present in the Number pool, Powerpack will use it to send the outbound SMS

  • If a phone number with 415 prefix is not found in the number pool, or if all the phone numbers with 415 prefix in the pool have already been used to recommended capacity (150 messages/day), Powerpack will deliver the SMS through any other phone number of the same region as the destination number (California in this case).

  • If no phone numbers of the same region are found in the Powerpack, the SMS would be sent via a random US phone number.

  • If no US phone numbers are found in the pool, the SMS would be sent via a Canada number.
