Text messages are always free

Pay for phones, not for texts

Your own Android phones and SIM cards do the sending, so there’s no per-message fee. You pay a simple monthly plan, plus only the extra phones, numbers and calls you use.

Billing questions

How can text messages be free?

Texts travel through the SIM cards in your own phones, using the plan you already pay your carrier for. We don’t add a second charge on top.

What happens when my free trial ends?

If you’ve added a card, your first $16 payment is taken when the trial ends, and that becomes your monthly billing date.

If you haven’t, your account is paused and nothing is charged. You can come back any time: add a card in Settings → Billing and reactivate for $16. There’s no second free trial.

What’s the least I can pay?

$16 a month. That covers one gateway phone, unlimited texts and unlimited team members. Everything else is charged only if you use it.

What if a payment doesn’t go through?

We’ll email you and try your card again over the next few days. If it still fails, texting and calling pause until the balance is paid.

To restore service, update your card and pay the overdue amount in Settings → Billing. You’re never charged for months your account was paused, and texts received in the meantime are kept on your phones.

Is there a contract?

No. You pay month to month and can cancel whenever you like.

What happens if I cancel?

Your account keeps working until the end of the month you’ve paid for, and the $16 plan isn’t charged again. Any extra usage from that last month, such as call minutes or extra phones, is billed once on a final invoice. Payments already made aren’t refunded.

What happens to my data if I close my account?

You have 60 days to change your mind and restore it. After that, your account and its data are permanently erased. While your account is open, nothing is ever deleted: removing something archives it.

Where do I find my invoices?

In Settings → Billing, choose Invoices and billing history. You’ll get a receipt by email after every payment.

Can I record calls?

Yes, at no extra cost. You’re responsible for following the call recording consent laws where you and the people you call are located.

Which countries can I call?

Calling rates shown are for the United States and Canada. Contact us for other destinations.
