Review plan and wallet information from the billing area.

## Review a call charge

1. **Open the call record** — Use Call Logs to find the call by ID or contact.
2. **Check its duration** — Compare the connected duration with the transaction detail.
3. **Review account transactions** — Open Billing and inspect recent call charges and wallet changes.
4. **Contact support** — Include the call ID and transaction reference when asking about a discrepancy.

## Before a large launch

Estimate the number of contacts and average call duration, then verify the available balance and plan limits. Run a small campaign first and review its charges before increasing volume.
