Internet broadband connection is much more faster because it is directly connected via physical connection from the modem (typical setup for home use). But now a days wireless internet can now compete with DSL thru a 3G/HSPDA network. In our country we can have a maximum bandwidth of 2.5Mbps using 3G wireless network.
Yes you can speed up your connection using your phone as a modem but you need to consider some aspects.
- your phone is a 3G capable phone
- you have 3G network signal that an indicator "3G"can be seen next to the signal meter of your phone.
- your network provider has 3G services.
What happen to you most likely is that your are connected using only a GPRS/EDGE. This is equivalent to a dial-up with maximum of 56kbps transfer rate. There is a great gap between the two if you compare it.
I already tested mine with maximum receive/downlink of 2,501 Kbps. I was really amazed.
Hope this things help you. If it does, please rate me.
