Increase your in-call and system volume levels. If still low, plug in earphones for clearer output.
Always include the correct country code (e.g., +1 for US, +44 for UK). Re-enter the number in international format before redialing.
CallMama SMS works over the internet (VoIP), not via your cellular provider. A stable connection is needed for sending or receiving.
Each minute of HD voice call uses about 1MB of data. Use Wi-Fi when available to avoid mobile data charges.
Inactive balance or expired plan could be the reason. Check your subscription status and renew if necessary.
