In most cases you should have a very good coverage as our network has 99% 4G coverage nationwide. Like all mobile networks, we can’t fully guarantee indoor coverage. Coverage in your house can vary depending on the type of building. For example, if your house is built with thicker materials or with the Minergie standard, or if you’re trying to access the network from a basement you may find it harder to connect to the network.
If you are calling within Switzerland, you have excellent coverage inside any building with a WiFi connection.
If you call or send a message from abroad, you avoid roaming costs: calls and SMS messages sent via WiFi Calling are charged at the same rate as in Switzerland.
To ensure that the phone does not connect to the mobile network, we recommend turning on flight mode first and then activating WiFi.
You can find a list of all WiFi Calling compatible devices here.
