iBall 21.0MP-58 21Mbps 3G Data Card  (White)

This product works well and so suggeting to manufacture the same for 4G , immediately and if it was already available , make the buyers , becoming aware of that.

this product is not at .all windows 8 compitable . i have purchesed from local store . it works good for 2g network but when attempt to connect 3g shows no device and even after reconacting displays same massage. ihave tried on genun windows8 . ultimately retailer replaced it with dlink deta card which is working very well

Great product works with 4g sim but gives 3g speed. I am really happy as it serves my purpose

This review is based on the first impressions of using the product. I use a BSNL SIM. I find that the device doesn't detect the SIM. Tried also with a T24 card with no success. I had gone through the reviews on Flipkart in details before placing the order, but didn't find any comment that it doesn't support BSNL cards. On installing the devices on my Windows laptop, I find that it gives option to detect only Airtel SIM. So my suspicion is probably correct that it doesn't work with BSNL SIM ca...

very good product, got delivered within 24 hours. Up to the expectation. Can use any sim with additional slot of micro SD, which supports up to 16GB. Overall good experience.

Good product with excellent Signal strength, good 3G speed and support voice Calls.

Cons:-
1)No Linux support (i didnt notice this before buying). But Technical support document shall be downloaded from website .Document is NOT clear.
2)Memory card holder design is very pathetic Old type like tray NOT Push type. Tray is very loose More chances of read/write fail due to loose contact.
