Signal marks :
G - poor signal 2G (GPRS) - internet speed 56-112 kbit/s
E - better signal between 2G and 3G (EDGE) - internet speed about 400-1000 kbit/s
3G - very good signal 3G (UMTS or HPSA) - internet speed about 384-3000 kbit/s

Small marks Ee means you are in roaming, if only one mark such as G, E, 4G is in your operator and if display shows Gr, Er, or something else you are in roaming with other phone operator.
