No, that’s definitely not the case. This is not an Android device, mobile data is disabled. I use the MobileID on the Swisscom SIM card, not the app!

The terms of use state: “To use Mobile ID, an active connection to the telephony and SMS services in your mobile service provider’s network is required.”

There is nothing about data connections.

I check the account balance before requesting a MobileID and after requesting a MobileID and my account balance empties. If I don’t use MobileID, my account balance remains the same, so no other application uses the mobile data. I’m also constantly on WiFi.

Thanks for your clarification regarding the mobile operating system. My quote of the device and system requirements comes verbatim from the [https://www.mobileid.ch/static/MID\_App\_NB\_DE.pdf](https://www .mobileid.ch/static/MID_App_NB_DE.pdf)

This is from the MobileID website itself, dated November 2020 and clearly states that a mobile data connection is necessary.

WLAN is of no use in this case, just as it is with MMS (I know: legacy - I’m just giving it as an example), where a mobile data connection is also mandatory and WLAN is of absolutely no use.

What is the source and date of your information? - It’s possible that something has changed.

Until a week ago, I regularly used Mobile ID as 2FA without a mobile data connection to access my Swisscom Kundencenter.

Unfortunately, I can no longer test whether it would still work.

At home or abroad?

This is about roaming.

@Anonymous

Sorry, I didn’t notice.

My use was domestically with a direct telephone connection to the Swisscom network.

There is a clear distinction in the document between use in CH and use in EU, but the device and system requirements do not differ in this respect: in both cases it says “… establishes an active connection to the SMS and data services in your mobile phone provider’s network.”

The fact that @Heiner70 observes a debit of (data) credit supports this announcement from MobileID.

sorry, I didn’t “invent” it (I can only read) 😁

@Heiner70 I tested it today with a work colleague from DE who also uses a Swisscom prepaid (inOne mobile prepaid) with Mobile ID.

1. Connection via WLAN -> Mobile ID works -> no debit.

2. Mobile data connection active -> Mobile ID works -> no debit.

3. Neither WiFi nor mobile data connection active -> Mobile ID works -> no debit.

Tariffs within EU/Western Europe:

Incoming calls (EU/Western Europe): 0.27/min.

SMS to Switzerland and to the country of residence (EU/Western Europe): CHF 0.27/SMS (Max. 160 characters)

Mobile data use above the basic tariff: Not possible as a cause due to the costs.

Please check on My-Swisscom which connection was exactly billed according to Verbindungsnachweis.

Then the MobileID will probably be handled via SMS. First request from MobileID during a login attempt: 0.27 CHF, response with the PIN again 0.27 CHF and then apparently another response from MobileID 0.27 CHF. A successful authentication costs me 0.81 CHF. I don’t currently have full access to mySwisscom, and I also doubt that there is relevant individual proof of connection there for prepaid.

But there is. In MySwisscom under Prepaid Usage => Connections. SMS are also listed there.

Hello everyone

Mobile ID can also be used free of charge abroad.

During a system change, some prepaid customers experienced malfunctions.

Thanks to your reports here, our technicians were able to find the cause and fix the error for all affected connections.
