Twilio: enable geo permissions for SMS before debugging send failures

TL;DR

New accounts ship with most regions disabled, so even a perfectly valid To number fails until you enable it. Check geo permissions before debugging your sending code.

Steps

1. That error is a console setting, not a code bug. Open the Twilio console, go to the Geographic permissions for SMS section, and check the permission for the destination region. New accounts ship with most regions disabled, so even a perfectly valid To number fails until you enable it. Check geo permissions before debugging your sending code.

Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.

Source: Stack Overflow #47423741 (answer score 240, from a Twilio developer evangelist): New Twilio user sends with live credentials and a valid To number, but gets "Permission to send an SMS has not been enabled for the region indicated by the 'To' number" even though SMS to the US should work. The fix is in the Twilio console under Geographic permissions for SMS: the destination region's checkbox must be enabled, which is off by default for many regions.

Verified resolution: That error is a console setting, not a code bug. Open the Twilio console, go to the Geographic permissions for SMS section, and check the permission for the destination region.
