The mobile network icons on smartphone and their speed

When your phone is connected to a mobile network, you will see an icon on its title bar (a.k.a. annunciator panel) indicating the type of mobile network it is connected to.

Have you been wondering what type of mobile network does that icon indicate, and what is its maximum upload and download speed? Here is the answer.

Icon             Network              Max Download         Max Upload
-----        ---------------       ----------------      -----------
  G               GPRS (2G)            14.4 kbps                 12 kbps
  E                EDGE (2.5G)        177.6 kbps               40 kbps
 3G              WCDMA / UMTS     384 kbps                 384 kbps
  H               HSDPA (old)        7.6 Mbps                 384 kbps
  H               HSUPA (old)       7.6 Mbps                     2 Mbps
  H               HSDPA              14.4 Mbps                   384 kbps
  H               HSUPA              14.4 Mbps                   5.7 Mbps
4G LTE          4G LTE               300 Mbps                 75 Mbps

Therefore, you will experience a slow network speed when the icon is either G, E or 3G; and you will experience a smooth network speed when the icon is H or 4G.

Note that most of the phones released earlier than 2012 are not supporting 4G Internet connection yet, and most handphone does not support HSUPA. HSUPA is more commonly used for home/office Internet broadband connected with wireless router device.

Both the phone and also the mobile operator's network infrastructure must support the network type in order for such Internet connection to be established for the phone.
