1) Is there any difference in the bandwidth/speed when we use a 2G sim or a 3G sim card?
2) Apparently there are two types of dongles
(a) One in which the sim is integrated with the dongle
( One in which we can insert any sim into the dongle
Is there any difference in the bandwidth/speed for these two types of dongles?
3) The Airtel site says that there are two models of dongles available:
(a) E153 with HSDPA 3.6 Mbps, chipset QUALCOMM MSM6246
( E1731 with HSDPA 7.2 Mbps HSUPA 5.76 Mbps, chipset QUALCOMM MSM6290
Will there be a difference in speed in the two models if I use a 2G sim card?
In other word, what will be the bottleneck the type of sim card or the model of the dongle?
