WHAT YOU WILL LEARN
Learning objectives
- Do not make a phone number your only recovery plan.
The useful habit
A phone number can be an account-recovery channel. Protect mobile-provider account access and prefer stronger supported authentication for important services. Unexpected loss of service deserves prompt investigation.
Apply it
Your phone loses service while account recovery messages appear elsewhere. Contact the mobile provider through known details and secure affected accounts.
