When you are connected to your mobile network, several icons can appear (listed below by order of conection speed):
- E : (EDGE or Enhanced Data rates for GSM Evolution) is the slowest data connection.
- 3G : (UMTS or Universal Mobile Telecommunications System) represents the 3rd generation data connection.
- H : (HSPA or High Speed Downlink Packet Access) is faster than 3G and is also called 3G+.
- 4G : (LTE or Long Term Evolution) is the last network mobile evolution and is also the fastest.
The 4G Network lets you have the fastest rates and provides a fast connection while the E network is the slowest connection.
However, true network quality depends on the congestion and the coverage. This is the reason why it is possible to encounter a slow connection even when on a 4G network.
Please note that you need to have a phone compatible with these standards to have them on your device.
