SMSbaserade

SMSbaserade describes systems, services, or applications that use Short Message Service (SMS) to communicate with mobile devices. The term is commonly used to refer to text-message based functionality that works on basic mobile phones without requiring data connectivity beyond standard cellular service.

Technically, outbound messages are sent through an SMS gateway via a short code or a regular long number, while inbound replies come from users. Operators and providers handle routing, encoding, and delivery reports. Many implementations rely on opt-in consent and support opt-out options.

Use cases include two-factor authentication codes, account or delivery alerts, appointment reminders, polls and voting, and marketing or information services. Interactive SMS can request user replies with predefined keywords, enabling automated workflows.

Benefits are broad reach, low device requirements, and simple setup. Limitations include variable delivery reliability, possible delays, costs per message, and strict length limits. Privacy concerns and data protection obligations require clear consent and transparent handling of personal data.

Security considerations include risks such as SIM swapping and message interception. As a result, many organizations supplement SMS with more secure methods for sensitive authentication. Regulatory frameworks, including GDPR in the EU, govern opt-in, data retention, and user rights for SMS-based services.

Although the popularity of SMS has declined with smartphone apps, SMSbaserade solutions remain in use for broad audience reach and as a dependable fallback channel, particularly in banking, logistics, and public information services.
