Causes of the “Message Blocking is Active” Error on iPhone

The “Message Blocking is Active” error can appear on an iPhone for various reasons, making it essential to identify the root cause before applying a fix. This issue can stem from service-related problems, device settings, or even account restrictions. Here are the primary reasons for encountering this error:

• SIM Card Issues: Misaligned or improperly installed SIM cards can cause messaging disruptions. eSIM users should verify their services are active.
• Network Problems: Temporary carrier or network outages might block messages temporarily.
• Account Restrictions: Carriers may restrict accounts due to policy violations, potentially blocking messaging services entirely.
