Why Facebook Stays Silent
-
SMS gateway overload during peak hours (typically evenings)
-
Facebook security: Five consecutive failed attempts trigger 24-hour lockout
-
Carrier blocking of international/short codes
-
VPN usage when IP country doesn't match phone number's country
-
Outdated SIM card or full message storage
Pre-Check Before Changing Numbers
-
Disable VPN and switch to mobile data to align IP with number's country
-
Verify phone format in settings: Must use E.164 standard without spaces
-
Restart your phone to clear SMS service cache
-
Check Spam folder in messaging apps
-
Use "Call Me" option - Facebook's robot will voice the code
These five steps resolve the issue for 79% of users (GrizzlySMS data, May 2025). If SMS still doesn't arrive, Facebook's temporary block is likely active. A new virtual number solves this.
