Secondary SIM

What is a secondary SIM?

A secondary SIM is an optional add-on for your main mobile subscription. Activate it whenever you want from your customer area for flexibility and comfort when using your smart devices (smartwatch, tablet or computer).

With the secondary SIM option, share your main subscription with up to four additional devices. You can then use them independently on your mobile operator’s network.
