Some of you may have presumptions that when 3G symbol appears on your smartphone’s screen, you get high download speed as compared to when symbol H appears but many of you have noticed that when a symbol H appears, browsing gets faster and data downloads very fast as compared to 3G symbol. But when E or G symbol appears, some of you may not like to use internet at that time because download speed gets very slow.
These symbols switches a lot during different times of the day even in the same location. So some of you might search a spot where you find stable symbol, preferably H or 3G.
Those who uses 2G connections, they can see two symbol E and G only while customers on 3G connections see G, E, 3G, H, H+ and symbols. Customer with 4G connections come across all symbols G, E, 3G, H, H+ and 4G symbols.
But what these symbols really means, technically !!. G stands for GPRS ( General Packet Radio Service ) and is the slowest standard used in 2G GSM network. E is an extension of GPRS and it is called EDGE ( Enhanced Data rate for GSM Evolution) under 2.5G network. It is a little faster on 2G GSM network.
3G (third Generation) stands for UMTS ( Universal Mobile Telecommunication System ) is faster than 2G network.
H and H+ are standing for HSPA (High Speed Packet Access) and HSPA+ (Evolved High Speed Packet Access), both use 3G UMTS network. H is faster than 3G and H+ is faster than H. 4G stands for LTE (Long Term Evolution) and is the fastest but now LTE-A (Long Term Evolution-Advanced) is the new standard which is super fast.
