There are various different connection methods for mobile devices:
- Cellular: This is where tablets and phones are using 3G, 4G, or 5G to connect to their provider without needing any other devices. Cellular connections are encrypted to prevent anyone seeing who is logging on or stealing your data. The problem that cellular faces is that if there are no masts nearby and the device has a setting of no service, they will not work.
- Wi-Fi: Connecting to a wireless access point is a common method of gaining access to the internet. The connection needs to be encrypted to prevent man-in-the-middle attacks. Some wireless providers have hotspots in major cities and airports so that their customers can connect.
