Skrill confirms every new wallet with an SMS code, and keeps using the phone afterwards for login challenges and payment confirmations. A virtual number from Get-SMS covers the registration step, letting you open a wallet without publishing your personal number to yet another financial database.
Be realistic about what the number does and doesn't solve. It passes the SMS checks — but Skrill is a regulated payment institution, and a wallet that will hold real money must eventually pass document KYC (ID, sometimes proof of address). The phone is only the first gate. Plan accordingly: a one-time number is fine to explore the service or receive a single transfer, while a wallet you'll actually operate deserves a 30-day rented number, because Skrill re-sends SMS codes on new-device logins and on many outgoing payments.
Keep the account's country consistent: Skrill assigns the wallet jurisdiction from the address you enter at signup, not from the phone code, but a US number with a German address and a third country's IP is the kind of mismatch that triggers manual review. After registration, switch the second factor to an authenticator app where offered, add a strong unique password, and the virtual number's job is done. If a number is rejected at signup as already used, cancel it free of charge and take the next one.
Skrill's sister wallet Neteller follows the same rules and the same checks — if you maintain wallets in both, treat them as separate registrations and give each its own number rather than re-using one.
