I have used tata phonton +, as others have mentioned, its speeds are pathetic, you get roughly around 256kbps, which is just about enough for browsing, but not good for the money you pay.
I have also used the Docomo wifi hub, the speeds are good but the device and the plans itself are pretty expensive...
My dad is still apprehensive about the UMG 1831 ebay deal. So, i have decided upon the micromax USB Modem, can't remember the exact model name/number. It's white in colour and the packaging is yellow/white. It's max speed is 7.2 Mbps and supports memory card upto 16 GB :'(
The dealer quoted 2.5k...i have to bargain with that
I want to buy a unlocked data card online (ebay preferred). I have shortlisted Huawei E173 and Huawei E1750. Is there any other option for me having download speed 7.2 mbps and upload speed 5.76 mbps? Do these cards have any known issues?
