Acceptable Use Policy

LundoSMS is for messages people expect and want. These rules protect recipients, keep the mobile networks open to us and keep your own sender ID in good standing.

Promotional messages need the recipient's consent. Every promotional message must make it easy to opt out — for example "Reply STOP" — and you must honour opt-outs. LundoSMS keeps opt-out lists and skips those numbers. Transactional messages must relate to something the recipient did or asked for.

Use a sender ID you own or are authorised to use. Never imitate a bank, government body, mobile operator or another brand, and do not switch sender IDs to get around a block.

• Fraud, phishing, scams or anything meant to deceive.
• Threats, harassment, hate speech or incitement to violence.
• Illegal goods or services, or content that breaks Tanzanian law.
• Adult or sexually explicit content.
• Malware, or links to malicious sites.
• Misleading claims about products, prices, health or finance.
• Unlawful election or political messaging.

Send at reasonable hours, do not send more often than people expect, and make clear who is writing. Never put passwords, full card numbers or other highly sensitive data in an SMS.

Use only numbers you obtained lawfully. Do not buy, scrape or guess lists, and remove anyone who asks you to stop.

Do not try to get around limits, probe or attack the platform, publish API keys or SMPP credentials, or use test mode to abuse the service.

We use automated checks and complaint reports. We may hold, reject or remove messages, restrict a sender ID or suspend an account — immediately, where harm is likely — and we may report serious cases to the authorities.

Received an unwanted message that was sent through LundoSMS? Tell us at abuse@lundosms.co.tz with the sender ID, the text of the message and the time you received it.
