Comparison FAQ
What is a non-VoIP number?
A non-VoIP number is a real carrier mobile number (not an internet VoIP range) that apps accept for SMS verification. Free VoIP ranges are often blocked, so reliable services route to genuine mobile lines.
Which payment methods matter?
Crypto is the norm in this space, but card payments are far more convenient for one-off purchases. VoIPStore accepts both — crypto via NowPayments and card via Stripe (credit/debit, Satispay, Revolut Pay).
What happens if my number never receives the code?
At VoIPStore the order expires and the number is auto-refunded to your balance — no ticket required. Refund behaviour at other providers varies, so check their terms before you top up.
Do any of these providers require KYC?
VoIPStore does not require KYC to get a number. Other providers' requirements vary over time — the table above marks this per provider and we keep it conservative.
