What Does "SIM Card Not Allowed to Make Outgoing Calls" Mean?

This message indicates that your phone recognizes the SIM card, but your mobile network is preventing it from placing outgoing voice calls. Depending on your carrier, you may still be able to receive calls, send text messages, or use mobile data, while voice calling remains restricted.

The restriction may be temporary or permanent, depending on the underlying cause.

Common Reasons for the Error

Several factors can trigger this warning:

• Your SIM card has not been properly activated.
• Your mobile plan has expired or has been suspended.
• The carrier has restricted outgoing calls due to unpaid bills.
• The SIM card has been blocked or blacklisted.
• Network registration has failed.
• Incorrect network settings are preventing proper authentication.
• The phone software contains a temporary bug.
• The SIM card is physically damaged.
• The phone is carrier-locked and incompatible with the inserted SIM.
• Roaming restrictions are preventing voice calls.

Understanding which situation applies to your device is the first step toward solving the problem.
