You deposit credits into your account and pay per number activation. Prices vary by country and service. If you don't receive the SMS, you get an automatic refund.

Are there any subscription fees?

Accepted Answer

No! Shadow SMS is 100% pay-as-you-go. No monthly fees, no recurring charges. You only pay for the numbers you use.

What if I don't receive the SMS?

Accepted Answer

If the activation fails and you don't receive the OTP, you get an automatic full refund to your credit balance. No message — no payment. We guarantee this for every activation.
