A disposable non-VoIP number is the safest way to verify Sideline / Index: you avoid SIM-swap exposure, keep your primary number off Sideline / Index's servers, and can spin up additional accounts for business, testing or travel. Free public numbers are usually already burned — a dedicated number from VoIPStore is fresh and high-deliverability.
Yes. VoIPStore issues real non-VoIP mobile numbers, which Sideline / Index accepts for SMS verification. VoIP-flagged numbers are frequently rejected, so we route you to genuine carrier ranges with high deliverability.
The number stays reserved long enough to receive your Sideline / Index code (typically up to ~20 minutes). You only need it for the one-time verification — it isn't a long-term subscription.
If no SMS arrives, the order expires and the number is auto-refunded to your balance, so you never pay for an unused number.
You can top up with cryptocurrency or fiat (credit/debit card, Satispay, Revolut Pay) and use the balance for any Sideline / Index number, in any supported country.
