Slovakia · Duet FAQ

Does Duet accept a Slovakia number?

Yes. The Slovakia (+421) number you receive is a real, carrier-grade mobile line that Duet treats as genuine — and it's sold once, so it arrives unused.

How fast does the Duet code arrive on a Slovakia number?

Usually within 5–60 seconds. The moment Duet sends the SMS, the code appears on your dashboard — nothing to install.

What if the Slovakia number gets no code?

If no SMS arrives within ten minutes, the order cancels automatically and the full amount returns to your wallet. You only pay for a delivered Duet code.

Can I choose a different country for Duet?

Absolutely. Any country in the list below delivers the Duet code the same way — pick Slovakia when you specifically want a +421 number, or switch to the cheapest in-stock option.
