Question 1: is the data volume only in Switzerland? I am close to the border and it often changes to the German network, it is no use to me if the SIM card only works in Switzerland and the foreign network does not, then I would rather buy the cheaper one for 40 and do it with my mobile or can I switch off the SIM with this one and go with WIFI and connect in the local hotel or then via my mobile? Question 2: I keep reading that if the device is not constantly charged, it stops working, doesn't respond etc. etc. Can you tell me anything about this? Can you tell me something about this? Question 3: do I also have the APP with this one and do I have to use it or can I check who has paid for what? I'm not sure, I'm an SME and need it mainly for small trade fairs, at stands and in hotels where my goods are bought directly. Thanks and regards R.
