I may soon buy the Huawei p20 dualsim. Is it possible to combine 2 sim cards, we take a cheap sim from here only to make calls and a sim with unlimited internet us abroad? Because I have seen when I was on vacation for some extremely cheap subscriptions and I suppose a subscription zb. From Italy for international use is still cheaper than an unlimited from Switzerland

Can forget, according to the small print and the EU Directive you can't permanently surf with a foreign SIM at their expense.

The maximum duration in which you can use a flat abroad is limited to a few weeks. So you can't get a cheap card z.Bsp. Obtain from NOrwegen and thus constantly surf in Germany.

You just have to get supplies. Fortunately, the cards do not cost anything.

No, that's not possible, you have to buy something German. Google would have known that too.

But with cards from the interior that goes in the case or? What about the phone number? Have to store all 2 numbers from me or can I eg. Register WhatsApp on my main number but if I send something is it about the other card? I just do not really understand this dual sim principle
