My payment was declined while purchasing a virtual number. What should I do?

Make sure your card supports international transactions and has sufficient balance. If needed, contact your bank to enable online or overseas payments. You can also try another card or payment method.

App says ‘Insufficient Balance’ while sending SMS.

Top up your SMS credits from the Billing section. Once funds are added, refresh the app to update your wallet balance.

Why do calls drop instantly after dialing?

Instant disconnection usually means:

Incorrect dialing format (always start with +country code).
Weak network or insufficient credits.
Recheck both and retry.

Can I send bulk SMS to multiple contacts?

Yes, from the CallMama web portal.

Each plan has a fair-use message limit to prevent abuse.
