Fastmail Verification FAQ
How fast do I get the number after paying?
After you top up your wallet (minimum $3 via crypto) and place an order, a real non-VoIP number is assigned instantly in your dashboard. Codes typically arrive in seconds to a few minutes. You are charged from $0.86 only when the SMS is delivered.
What payment methods are accepted?
Wallet top-ups use Cryptomus crypto checkout (wallet top-up). Minimum deposit is $3. Orders debit wallet balance only when the verification SMS is successfully delivered (pay-on-delivery). Timed-out orders credit the wallet automatically.
Does Fastmail accept non-VoIP numbers?
