Add call and text to travel eSIMs worldwide

eSIM with call and text for travel eSIM providers

Travelers increasingly ask “can you make calls with eSIM?” because data alone no longer solves real travel needs. They need to contact hotels, verify transactions, receive local messages, and stay reachable on trusted numbers. When voice and SMS fail, the experience feels incomplete, and the provider loses trust.

 

For travel eSIM companies, this creates a clear moment to evolve. Adding voice and SMS increases plan value, improves retention, and opens new revenue tiers. BICS supports this evolution with infrastructure that already connects operators, regulators, and networks worldwide.

From data-only eSIMs to full mobile service for travelers

Why data-only eSIMs fall short for travelers

Data-only eSIMs connect users to the internet, but they do not support native calls or SMS. Travelers either rely on apps or keep their home SIM active, which introduces roaming costs and operational friction. The providers who want to expand beyond data add voice and messaging at the network level.

Cloud-based voice and SMS integration

Providers can add calling and texting using cloud communication services that operate over data. BICS enables this with cloud numbers, two-way voice, and SMS in multiple countries. You integrate these components into your platform, design your own bundles, and launch voice-enabled travel eSIMs without building telecom infrastructure from scratch.

Built for real-world traveler behaviour

Most travelers use dual-SIM devices. They keep their home SIM active for SMS and use a travel eSIM for data. BICS supports this behaviour with roaming orchestration, regional breakout, and dual-SIM readiness. These capabilities reduce latency, optimize routing, and help you control costs while delivering a stable experience across networks.
