Sim Card and USB dongle for 3G service
Posted 02 November 2012 - 02:16 PM
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?

Just did some googling and apparently there is a way to differentiate between the two cards.

The bottom line is : can I get the 7 Mbps/21 Mbps etc. using my old sim card?
At this link The Difference Between 2G & 3G SIM Cards | eHow.com it says the following:
The major difference between 2G and 3G SIM cards lies within the rate of data usage and transfer. In 2G SIM cards with GPRS/EDGE, data services can transfer between 56 and 236.8 kilobits of data per second. However, 3G SIM cards can transfer 14,400 kilobits per second. This makes 3G SIM cards better for downloading data like Web pages and multimedia.
Will a higher end modem help?

Where there is no 3G signal, the performance gets downgraded.
Will it make a difference if I use the 2G (3G enabled card) in a higher end dongle modem?
My sim is 3 years old, so I am pretty sure that it is a 2G sim card.
Also we can tell a 2G sim from a 3G sim according to this link
