Sinch/Topcashbac SMS verification — FAQ
Can I receive Sinch/Topcashbac OTP codes with a non-VoIP number?
Yes. VoIPStore issues real non-VoIP mobile numbers, which Sinch/Topcashbac accepts for SMS verification. VoIP-flagged numbers are frequently rejected, so we route you to genuine carrier ranges with high deliverability.
How long does the Sinch/Topcashbac number stay active?
The number stays reserved long enough to receive your Sinch/Topcashbac code (typically up to ~20 minutes). You only need it for the one-time verification — it isn't a long-term subscription.
What if I don't receive the Sinch/Topcashbac code?
If no SMS arrives, the order expires and the number is auto-refunded to your balance, so you never pay for an unused number.
Which payment methods can I use?
You can top up with cryptocurrency or fiat (card / PayPal) and use the balance for any Sinch/Topcashbac number, in any supported country.
