The recipient’s number might be switched off or blocked for VoIP SMS. Try resending later or verifying that the number supports virtual SMS delivery.
This delay may occur due to temporary carrier congestion or DND (Do Not Disturb) filters. Messages are usually delivered within 5–10 minutes.
CallMama SMS works over the internet (VoIP), not via your cellular provider. A stable connection is needed for sending or receiving.
Logging out and back in forces a fresh sync with our main server. Ensure both devices are using the same account.
Your messages are tied to your CallMama account, not your SIM. Log back in using your same credentials to recover them.
