hi guys I bought a beetel 3g modem device model no mf190 at a price 2400/- But when i checked the download speed with a demo 3g bsnl sim i just got frustrated.i checked the speed in huwai 7.2 Mb and huwai 3.6 Mb supporting device and both the device gave more speed than my device though my device support 7.2 Mb.I checked all this with same sim, same place and with same laptop. so my question is. 1)is there any problem with my device?Any explanation? 2)how to increase the speed? Seller will not refund the money as he only promised me that the device will work with every GSM sim. 3)So any other way to fix it? Now i'm using this device with aircel 2g sim(EDGE) and getting 15-20 KBps download speed. 4)Is it normal? I'm planing to buy a BSNL 2g sim as in my place 3G sim is out of stock and they can't when it will be available again. 5)can anyone tell me what is the download speed in 2g sim of BSNL? I think it will give more speed than Aircel as bsnl unlimited internet cost 274 and aircel unlimited cost 98 only. Anyone using this device please post your experience and suggestion plz.
