Is it more appropriate to rent an egg at the airport or buy a SIM card abroad when traveling to Italy and Switzerland ?

You can also make phone calls with the card as a precaution, and the cost turns out to be cheaper than WiFi.
Try to buy good phone cards and use iPhones when you are outside. Huawei phones don't work well in Europe and you can't use Google Maps.
In my opinion, it's more convenient to buy a foreign phone card on Fliggy.
