Inbox activity matters more than the label alone

Before focusing only on the country, check whether the inbox still shows fresh messages. That is often the better signal.

A simple region strategy

  • Start with the US, then try the UK.
  • Move Hong Kong earlier for Asia-oriented cases.
  • Keep two or three regions ready as backups.

What to do after repeated failure

Switch numbers first when an inbox looks stale, then switch countries when several numbers in the same region still fail.
