The details to check differ before ordering, while waiting for SMS, and during top-up. Start with the path that matches your current action.
Before ordering
Some platforms restrict virtual numbers. Check compatibility, service, country, platform sell price, and inventory estimate.
While waiting for SMS
Separate waiting, completed, timeout, failed, cancelled, and verification states. Do not duplicate an order solely because a request timed out.
When topping up
Use an active top-up order and verify its asset, network, destination, and exact amount. Mismatches may require further verification.
FAQ
Common questions about OTP, deposits, rentals, API, and account security.
Can guests browse services and prices?
No. The public website only introduces the product. Real services, countries, stock, and prices require sign-in.
How long does a deposit take?
Deposits are credited after the configured chain confirmations. Chain, asset, or amount mismatches go to manual review.
What should I do if the SMS does not arrive?
Check the order status first. If cancellation succeeds, or the platform confirms after the required period that no SMS arrived and the order qualifies for a refund, the amount returns to the platform balance. An unclear result remains under verification. Do not duplicate an order solely because a request timed out.
Can I cancel a rental number?
Users cannot cancel an activated rental. A definite procurement failure is refunded in full; service interruptions are reviewed manually and any refund follows the platform decision.
How should I protect API keys?
API keys are shown only once at creation. Configure a fixed egress IP whitelist and revoke leaked keys immediately. Webhooks use the active API key and do not create a separate signing secret.
Why does the price API return one price only?
MangoOTP returns the current platform sell price and inventory estimate without exposing internal providers or routes. Current price and inventory are reloaded at order creation.
Why does order creation require sellPrice and an optional ceiling?
sellPrice is the price just observed by the partner. Without maxSellPrice it must match exactly; with a ceiling, the current price may proceed only when it does not exceed that ceiling.
Can referral commission be withdrawn?
Released commission can be withdrawn according to platform rules. Users must bind a withdrawal wallet and pay the configured chain fee.
What if I cannot receive an email code?
Check spam, spelling, and send-rate limits. If it still fails, send your account email and request time to support.
Which use cases can be restricted?
Illegal, fraudulent, credential-stuffing, abusive bulk usage, payments, and high-risk financial scenarios can be restricted or manually reviewed.
Still need help?
Send your account email, order number, deposit transaction hash, API request ID, or screenshots so support can locate the issue quickly.
