# How do you use SMS for payment and transaction alerts?

> SMS payment and transaction alerts notify customers in real time about debits, credits, low balances, and suspected fraud — a core requirement for banks, fintechs and payment providers. These messages must be fast, reliable and sent over direct routes with a strong SLA, classified as transactional (never marketing), and free of sensitive data such as full card numbers. See /solutions/banking-finance.

## Real-time reliability is non-negotiable

A fraud or debit alert has value only if it arrives immediately. Send over direct, high-priority routes with route failover and a published uptime SLA — BroadNet runs a 99.99% platform SLA. See /answers/what-is-route-failover and /answers/what-is-throughput-sla.

## Keep it transactional

Transaction alerts are essential-service messages, not marketing, and must be classified and routed as transactional so they are never throttled with promotional traffic or dropped for missing marketing opt-in. See /answers/how-to-register-sender-id.

## Fraud alerts and two-way confirmation

Let customers reply YES/NO to confirm or dispute a suspicious transaction, turning an alert into an instant fraud-control loop. See /products/two-way-sms and /answers/telecom-fraud-prevention.

## Security and data protection

Never put full card numbers, passwords, or one-time codes for other sessions in an alert. Mask account identifiers and comply with regional data-protection law. See /answers/gdpr-for-messaging and /answers/pdpl-ksa-explained.
