Hello @Eluria and welcome to our o2 community :-)

If a mobile phone is connected to a wifi network this does not automatically means that it will not also connect to a mobile network. Modern phones offer several features and settings and sometimes also special apps that will access a mobile network even if a wifi connection is establihed. There may even be malware that totally ignores any settings that a user makes.

Since we do neither have access to your phone nor lies it in our responsibility to make sure that a device is set up in the way that you want it to be we will not be able to offer a refund.

A possibility to avoid the phone accessing the mobile internet would for example be to remove the SIM card or ask the customer service if blocking the mobile internet would be a possibility. 

Regards,

Lars

Hi Lars, thank you for the reply. Is it possible for that auto connection service to be turned off?

Best,

Hello @Eluria ,

as Lars already said, that depends on the phone and the apps that you are using. We can only offer to completely bar your contract from using mobile data at all.

Kind regards, Sven
