Out-of-Bundle Usage & Credit Safety
If you completely exhaust your 1,000 or 777-minute call caps before the 30-day window closes, your connectivity will stay live as long as you have funds in your main wallet. Excess usage defaults to standard out-of-bundle rates:
- Voice & Calls: Charged per minute at basic network rates to domestic lines.
- Internet Traffic: Excess data usage beyond the 2GB pool is billed at Rs. 0.30 (+ taxes) per megabyte (MB).
- Wallet Safety: For prepaid users, if your main wallet balance hits exactly Rs. 0.00, your active booster minutes will continue to work without disruption until the 30 days expire.
