Acceptable use
Last updated 13 November 2026
These are the rules for sending through RDNC SMS. You agree to them when you create an account. They exist because a sender ID is registered with carriers in RDNC's name — what you send reflects on every other client on the platform, and on RDNC.
1. Consent
Only message people who have agreed to hear from you. A phone number you bought, scraped or were handed by someone else is not consent. If a recipient asks you to stop, stop — and keep a record of when and how consent was given, because you may be asked for it.
2. Your sender ID
The sender name must be your own registered business or product. You may not use a name that belongs to someone else, or one that suggests you are a bank, a government agency, a courier or any organisation you are not. RDNC reviews every request and may reject or revoke a name at any time, including after it has been approved.
3. What you may not send
- Anything designed to deceive — phishing, fake prizes, fake delivery notices, fake bank alerts.
- Loan sharking, gambling, adult content, or anything illegal under Philippine law.
- Unsolicited bulk messaging of any kind.
- Threats, harassment, or content targeting a person.
- Anything impersonating another business, person or agency.
4. Your account and keys
Your API key and secret are yours to protect. Anything sent with them is treated as sent by you and charged to your balance. Tell RDNC immediately if you believe a key has been exposed — you can disable or delete one yourself at any time from your dashboard.
5. Credits and payment
Credits are prepaid and are deducted when a message is accepted by the network. Credits for recipients the network refuses are returned automatically. Credits do not expire. They are not exchangeable for cash, and unused credits are not refundable except where RDNC has failed to provide the service.
Scheduled messages take their credits when you schedule them. Cancelling before they send returns those credits in full.
6. Delivery
RDNC passes your messages to a telecommunications network. Delivery depends on that network and on the recipient's carrier, handset and coverage, none of which RDNC controls. A message accepted by the network is charged for whether or not it is ultimately delivered. RDNC does not guarantee delivery times.
7. Suspension
RDNC may suspend an account immediately, without notice, where there is reason to believe these rules are being broken, where a carrier requires it, or where messages are causing harm. Where it is reasonable to do so, RDNC will explain why and give you a chance to put it right.
8. Changes
These rules may change as carrier requirements change. Material changes will be announced to account holders before they take effect.
