Wi-Fi and mobile Internet (3G or 4G)

What is the difference between Wi-Fi and mobile Internet (2G, 3G, 3G+ or 4G)? Surfing via Wi-Fi is cheaper than surfing via mobile Internet, but the Wi-Fi signal is limited to a small area, such as a cafe, airport, etc. To see the differences, you can compare the Wi-Fi Hotspots map and the network coverage map.

With your SIM card, you can use the following networks: 2G (GPRS or EDGE), 3G (UMTS), 3G+ (HSDPA or HSPA+) and 4G (LTE). You may be switched from one network to another (e.g. from 3G to 4G) because your device always chooses the best available network.
