Step-by-step: Add money to the wallet (manual top-up)

1. Log in to the SIGNL4 web portal.
2. Open Billing from the main menu.
3. Scroll to “Prepaid settings for voice calls and text messages” and select Edit.
4. Choose a Top-Up Amount (for example, $10, $25, or $250).
5. Click Add Funds to immediately fund the wallet.
6. Confirm the transaction. The new balance will appear in the same section.

Step-by-step: Enable Auto Top-Off (optional)

Use Auto Top-Off to automatically replenish the wallet when the balance reaches a threshold.

2. Set the Auto Top-Off Amount ($10, $25, or $250).

4. Save your changes. When the wallet balance drops to the threshold, SIGNL4 will automatically apply the selected amount.
