Cellular coverage inside buildings can be a problem for many users in Switzerland. However, there is a simple and convenient solution to resolve this issue: Wi-Fi calling.
Swisscom, Sunrise, and Salt all offer Wi-Fi calling within their services, allowing users to make and receive voice calls via a Wi-Fi connection instead of the cellular network.
Using Wi-Fi calling can solve indoor cellular coverage issues and offer numerous advantages, including:
- Greater coverage: Since Wi-Fi calling allows for making and receiving voice calls via a Wi-Fi connection instead of the cellular network, users can enjoy wider and more reliable coverage inside buildings.
- Better audio quality: Thanks to the Wi-Fi connection, voice calls made via Wi-Fi calling can have better audio quality compared to calls made over the cellular network.
- Increased security: Since voice calls made via Wi-Fi calling are encrypted and protected from potential intrusions, users can enjoy greater security during their calls.
Ultimately, Wi-Fi calling is a simple and convenient solution for solving indoor cellular coverage problems in Switzerland. Swisscom, Sunrise, and Salt all offer Wi-Fi calling in their services, allowing users to make and receive voice calls more reliably and conveniently.
