What is Feimao SMS?

Feimao SMS (飞猫短信) hosts your own eSIM and receives SMS through catesim.cc. Even without an eSIM phone, you can request SMS windows and read your own number's messages in a browser, without separate receiving equipment. You supply an SMS-capable eSIM whose supplier permits hosted installation. Continuous availability and successful third-party verification are not included.

We do not sell numbers or create third-party accounts. The service receives SMS only, with no calls, mobile data, or outgoing SMS. Website access and third-party regional eligibility must be checked separately. Compare a phone, a self-built modem, and hosting, and use the supplier questions before buying.

Getting started

1. Register and add an eSIM you own or are authorized to use, with SMS support and permission for hosting, on Numbers. Ordinary registration starts with zero credits.
2. Buy or redeem valid credits on Plans. Saving details and buying credits do not install the eSIM. The supplier separately charges for the eSIM, renewals, and any replacement codes.
3. Choose a number and request a window. Wait for queueing and preparation, then request the third-party SMS only after “Ready to receive”. Read “Recent messages” on Numbers; full history is in Messages.

The first confirmed view of each complete SMS uses 1 credit. Viewing it again and copying are free. Receipt, previews and refreshes use no credits. A request reserves 1 credit. Its first linked message uses that reservation; each further message uses another available credit. An unused reservation is released when the window ends, with its original expiry. Credits are valid for 365 days. Supplier purchase, renewal and replacement fees are separate. Messages already in the inbox before this change keep their previous rules.

Where are recent messages and full history?

“Recent messages” on Numbers shows the latest three messages for the selected number, across requests. Each row includes sender, Beijing time and masked preview. Refreshing or starting a new request keeps this list.

Open Messages for full text, more messages, and earlier history, and check the selected number. Eligible delayed old messages keep their original times and delivery marker. Viewing a masked preview uses no credits. Confirm viewing a complete SMS to use one credit.

How do I pay and check credit delivery?

Choose a package, confirm the order, and pay its exact amount through Alipay. Payments are normally confirmed automatically before credits arrive. If manual handling is shown, follow the original order’s instructions to select “I have paid” or contact the administrator. A button click or return from Alipay does not confirm delivery; check the order’s status.

After refreshing, closing the page, or logging in again, resume the same order from Purchase history. Do not pay twice. If processing takes longer than expected, the amount differs, or you have another question, provide the order number for review. Keep your actual payment record and hide details unrelated to the order in any payment screenshot. Independent voucher redemption is handled separately from payment orders.

My overseas eSIM receives no code. What should I check?

1. Stage: wait during queueing or preparation; the five minutes have not begun. Follow maintenance, unavailable, or uncertain-result instructions rather than assuming readiness.
2. Number and window: check the selected number and request. Ask for SMS only after “Ready to receive”. Request another window if the old one has ended and you need more time.
3. Third-party response: check number format, sending status, and resend rules. Number acceptance, timing, operator, and network conditions affect delivery. Avoid rapid repeated retries.
4. Location and times: check recent messages, then Messages. Delayed old SMS does not count as a new code, and delayed delivery does not change original times.
5. Errors: recheck SMS support, expiry, and supplier conditions. For continuing problems, tell the administrator the page status and approximate time. Do not blindly delete, transfer, or reinstall.

Old messages can be shown only under the ownership rules when the same number is next ready. See the illustrative receiving steps for the full sequence.

Will my number stay online all the time?

Installed profiles are not automatically removed when a window ends or after a set time. Removal may follow an explicit deletion or transfer out, or occur under the rules when the card is full. Saved details and messages within their retention period remain subject to platform rules. Staying on the card does not mean continuous availability or access to new messages at any time; request a window when needed. Reinstallation must meet supplier conditions, and code reuse may be unavailable or require a paid replacement. Check the supplier rules before deletion, transfer, or reinstallation.

How long are messages kept?

Messages are kept for three months, calculated as 90 days from the original receiving time. Delayed delivery, syncing, retries, or restoration do not restart this period. Expired messages cannot be viewed or exported. In Messages, delete an individual SMS or clear all messages for the selected number, across all pages and regardless of the current search. Deleted messages cannot be restored from customer pages; credits already used to view them are not refunded. Save anything you need longer before it expires, and protect verification codes.

Account, contact, and appeals

Google login receives only an identity identifier and email; it does not read Gmail. An existing account with the same email must be verified before Google is linked. Manage login methods and a backup password in Account.

After logging in, the contact icon at the top shows the administrator's existing contact details. View private support records in account help and support. If you cannot log in, use account recovery. For a review of service restrictions, privacy, or charges, provide your account email, related reference numbers, and the necessary explanation. Do not provide passwords or complete activation codes.

Before using the service, read the Terms of service, Acceptable use policy, and Privacy policy.

Credit expiry and invitations

Credits are valid for 365 days after they arrive in your account. The earliest-expiring credits are used first; check expiry dates in Account and Plans. After a real purchase delivers credits or a voucher is successfully redeemed, you can obtain an invitation code in Account. A friend’s first registration with a valid invitation only links the invitation; it adds no credits. You each get one credit after the friend’s first paid platform purchase successfully delivers credits, with no minimum spend. Voucher redemption, administrator grants, receiving charges, and selecting “I have paid” do not trigger rewards.

Each inviter can earn up to 30 rewards per Beijing calendar month, based on when the platform confirms the payment; registration reserves no monthly capacity. No reward or later replacement is issued if the limit is full, the offer is closed, or either account’s service is paused at first-purchase settlement. Rewards expire 365 days after actual crediting. Existing rewards stay unchanged. An invitation code can only be added at first registration.
