Is the kangaroo island signal good?

The communication signal of Kangaroo Island will be very strong in areas where hotels and crowds gather, and the signal of general scenic spots and self-driving roads will be weak or even no signal. Therefore, we should deal with the matters that need communication network before departure. Although the hotel has Wi-Fi service, only a part of it is free, usually before 100M-250M, and then you need to register the credit card purchase process. When booking a hotel, you need to check the network tariff.
