You used to have to register with your cell phone number and receive a text message that was valid for a certain period of time. At some point I installed the M app and also connected it to my Cumulus number.

For some reason I deleted the Migros app and then realized that access to MIGROS WIFI had also disappeared.

Does this have a connection? If I reinstalled the M-App and of course connected to the Cumulus number, would access to MIGROS WIFI be restored automatically ? -- Or how does this work?
