What should I ask my supplier before hosting my own eSIM?

A number, SMS support, hosting permission, and verification acceptance are different

1. Your right to use the number. Add only an eSIM you bought or are legally authorized to use, for your own third-party accounts. Keep the order and terms; avoid activation details of unknown origin.
2. SMS reception. Explicitly confirm a usable number and enabled SMS reception. Hosting cannot add SMS to a data-only eSIM. A number or product name alone does not prove that verification messages can be received.
3. Hosting and installation permission. Confirm hosted installation and check device, location, activation, and transfer restrictions. Feimao SMS does not promise universal supplier compatibility; saving details is not compatibility evidence.
4. Third-party acceptance. Receiving SMS and completing verification are separate outcomes. Check the target website's current regional eligibility, number types, and account rules. This platform cannot guarantee delivery or acceptance.

Questions you can send directly to your supplier

Ask about your specific plan and keep the answers. “Does it support eSIM?” is not enough: SMS, hosted installation, and reinstallation each need a clear answer.

1. Does this exact plan include a usable phone number? Can it receive ordinary SMS and verification messages, with any sender or location restrictions?
2. Do you permit installation on a third-party hosting device for SMS reception only? Are there device, location, roaming, or first-activation conditions?
3. Is it already active or installed? If it is on another device, what transfer steps are required, and must you confirm release first?
4. If a profile is later deleted, transferred out, or removed because the card is full, can it be installed again? Can the original QR code be reused, is reuse limited, or is a replacement required?
5. Are replacement codes or reinstallation charged, and is there a waiting period? Local deletion alone does not prove supplier permission to reinstall.
6. When do the number and plan expire, and how do I renew? Are there balance, number-retention, or usage conditions for receiving SMS?

These questions help establish conditions; they do not answer on the supplier's behalf. Clarify uncertain answers before buying or installing. Do not test unknown rules by repeatedly deleting, transferring, and reinstalling.

Then save details and prepare credits

Adding eSIM details on Numbers does not install the number or use a receiving credit. Buying credits does not install it either. Preparation is queued only after you choose a number and request a window. See the first receiving request guide and How it works.

Ordinary registration starts with zero credits. Listed prices are CNY 2.90 for one use and CNY 9.90 for five; the confirmed order sets the amount due. You can also redeem a valid voucher. Each credit batch lasts 365 days. The supplier's number expiry is separate, and buying credits does not renew the number. See Pricing for separate eSIM, renewal, and replacement-code costs.

Understand receiving and retention before use

A five-minute window begins after preparation; queueing and preparation do not use that time. The first confirmed view of each complete SMS uses 1 credit. Repeat views and copies are free; receipt, previews and refreshes use no credits. A request reserves 1 credit for its first linked message. Further messages each use another available credit; unused reservations release at the end with their original expiry. Any qualifying complete new SMS starts the 30-second early-close timer, and you can wait until the original five minutes end. Backlog, old or unknown send times and incomplete multipart SMS do not trigger early closure. Previously published messages keep their original rules.

A window ending does not trigger timed removal. Removal may follow an explicit deletion or transfer out, or occur under the rules when the card is full. Retention does not mean continuous availability; request a window when you need SMS. Messages expire 90 days after their original receiving time. If you are choosing equipment, compare a compatible phone, self-built modem, and hosting. See Help for everyday use.

Protect activation details

Keep original activation details and supplier records. Do not publish full QR codes, activation codes, or verification codes. For help, log in and use the administrator contact at the top, explaining the plan conditions and page status. Do not post your password or complete activation code in public support requests.
