# Auto Top-Up: Never Run Out of Credit

> Switch on auto top-up once, and CallTuv quietly adds credit whenever your balance runs low - so a call never cuts off mid-sentence.

**TL;DR:** Flip the Auto top-up switch on the Balance page and CallTuv automatically adds $10 whenever your balance drops below $5 - so calls never cut off mid-conversation.

Auto top-up is a "set it once and forget it" feature: whenever your balance drops below **$5**, CallTuv automatically charges your saved card **$10** and adds it to your balance. Your credit simply never runs dry - no interrupted calls, no remembering to top up before phoning family on the weekend.

## Why you might want it

Two slightly annoying things happen when a balance reaches zero:

- A call **in progress ends by itself** the moment the next minute can't be paid for - possibly mid-sentence.
- New calls can't start until there's enough credit again (at least the [3-minute minimum](/help/6829471-minimum-balance-to-start-a-call)).

With auto top-up on, neither ever happens - the balance refills before it empties.

## Turning it on, step by step

Auto top-up is managed on the website (not in the app):

1. Open your browser, go to [calltuv.com/balance](https://calltuv.com/balance), and sign in if needed.
2. Make sure you have a saved card. If you've topped up by card before, you already do. If not, do one normal [top-up](/help/8412937-how-to-top-up-your-balance) first, or add a card via **Manage Payment Methods**.
3. Find the **Auto top-up** switch on the Balance page and turn it on. You'll see a confirmation that it's enabled.

From now on it works silently in the background: balance dips under $5, your default card is charged $10, the credit appears, and an [invoice arrives by email](/help/2085461-invoices-receipts-and-vat-details) - just like any top-up.

## Turning it off

Same place, same switch - flip it off on the **Balance** page and it stops immediately. Nothing else changes; your remaining balance stays put and you can still top up manually whenever you wish.

## Good to know

- Auto top-up is a team setting, controlled by the [team owner](/help/8241695-inviting-and-managing-team-members) like all billing.
- It happily coexists with manual top-ups - add a larger amount by hand any time you like.
- If an automatic charge ever fails (an expired card is the usual culprit), simply update your card under [Manage Payment Methods](/help/2417850-managing-saved-payment-methods) and top up manually once - then you're back on autopilot.
