Backup internet

A backup connection must work when your main connection fails. Buying a SIM alone does not create a working failover solution.

Use cases in this guide

We do not yet show confirmed, comparable offers for this use case. Use the checks below when speaking with your manufacturer, installer or provider.

Choose the applications that must keep working and the required duration. Check whether the router switches over and back automatically.
Check that backup connectivity does not share the main connection’s vulnerability. Ask about network, power and router placement.
Test an actual outage with the required apps. Check recovery, caps and how you detect faults or exhausted data.

Include router, optional antenna, installation, standby charges, activation, usage and support.

Compare the same outage duration and traffic. A low monthly charge may cost more during an extended outage.

Which services remain available during failure, how does switching work and what does a representative outage cost?

Take this question, your device model, countries and usage to the provider.

First choose how to share internet: from a phone or a separate router. Not every travel eSIM works in a router.

Device and purchase checks

Start with connections and environment. A mobile hotspot, industrial gateway and fixed failover router solve different problems.

Device and purchase checks

First ask the installer or monitoring centre to confirm the required connection. An ordinary data plan may omit essential functions.
