Find every dependency
List important accounts, contacts and services that use the existing number. Verification messages can be especially important. Update those details through each organisation’s official settings while the old line is still available.
Understand STAC
For the standard single-number text-to-switch process without keeping the number, text STAC to 75075. Give the resulting code to the new provider as instructed. A PAC serves a different purpose: retaining the old number.
Separate activation from closure
A new SIM working with a new number does not by itself demonstrate that an older account has closed. Follow the official switching or cancellation process and retain the confirmations. Review any separate handset agreement.
Check your recovery options
Make sure important accounts have current recovery details. Do not depend on access to messages sent to the previous number after the old service ends. Contact the relevant organisation if changing a verification method requires additional steps.
Take these checks with you.
- Important accounts updated.
- Correct switching route selected.
- Old account status confirmed.
