In order to activate the Voice Roaming Option (for incoming SMS and international calls), as well as value added services, you need the following:
- An active voice package on the SIM card or the Flat Mobile: How can I use the voice option as an existing customer?
- A valid payment method must be stored in your customer account: How can I adjust my payment method?
- A valid identity document (Swiss passport/ID or residence permit)
- A Swiss address
- Selfie with ID document clearly visible in hand
Please note that international calls are not included in the voice option or Flat Mobile and will be charged separately.
You can send us the missing data directly via contact form.
