i have recently purchased this product. Till now I was using 300g.
This is excellent in RS 1225 .The best part are
1. all gsm sim cards can be used
2. built in profile for all sim cards no need to make it manually
3. YOU CAN CHECK YOUR BALANCE (OF ALL KINDS) WITHOUT INSERTING IT IN MOBILE
4. good speed
DISADVANTAGES
1. NO CALLING FACILITY

At the price of Rs. 1226.00 the product is too good. I was fed up with photon...they charge too much for a decent speed. But with MMX 310...both price and speed are in my range. Good for students...a must buy. And three cheers for Flipkart...lowest price and fastest delivery.

RECEIVED 4TH DAY FROM ORDER. THANKS FILPKART FOR QUICK DELIVERY AND VERY GOOD PACKING.
IT GIVES GOOD SPEED IN BOTH 2G AND 3G. ALSO WE CAN SEND AND RECEIVE SMS. PRICE IS VERY REASONABLE. IT SUPPORTS ALL TYPE OF GSM 2G AND 3G SIM'S. WE CAN CHECK OUR BALANCE ALSO. OVERALL IN COMPARASION TO PRICE IT IS A VERY GOOD PRODUCT.

ya it is a best product i ever seen speed is great but sim slot is delicate overall performance is good, you cant make call or receive, but u can send and receive messages. their's logo of BSNL on it.

If you are a Linux user then you must not buy it. The specifications on this website also indicates that it doesn't support Linux but when you will purchase it from the shop you will find System Requirements as - Windows, Mac, Linux Ubuntu 9.10, 10.04. I too bought after seeing that. But actually NO Micromax device supports Linux. When contacted to Customer Care, they sent me a Linux Interface which doesn't run properly OS. It was a kind of 'jugaad' and was a degraded version. On complaining ...

Well, the review title said it all...Bought it on october, 2009 & very happy with it. All I did is just upgraded the firmware & also downloaded the latest software. My default software did not support the "USSD" function.

The only con is calling feature is not available but most of the dongle users uses different sim for dongle so this would not be a big deal as it's supports "USSD' & "SMS" for balance & data usage inquiry. It supports auto connect, no configuration is needed to connect.

So...

the performance of datacard is good. its working in both 2g and 3g platform and am able to browse net with good speed even in 2g.

the only problem i face is when am inserting and ejecting the sim card. its pretty diff.

but when compared to uses and the price its performance is the best and i will recommend to my friends too to us use it. i got the product on the 3rd day after i ordered

One of the great product from Micromax. Initially I had been in doubt whether to buy this or not. One of our computer technical adviser suggested my father to buy this. Before that I had been using BSNL 3G data card. Micromax 310G is much times better than BSNL. I have been using this for three years. It is now showing no defect in it and works finely as it was 3 years before. I planed to gift this to my brother on his birthday, but I cann't find the product anywhere. Perhaps this has been d...

nice modem. received it on the second day.
works very fine. i'll recommend everyone to buy this one coz the other higher price models available they just show the hsdpa speeds upto 7.2 or higher but it never goes upto that limit. infact it never even crosses 1mbps speed.

i got this 2 days back and comming to product at fist while seeing the pack it is bsnl 3g logo but it is unlocked no need to worry

advantages

1:looks good
2:unlocked
3:automatic setting for any sim card no need of manual settings

dis advantages:

1:length of product is big compared to other data card
2:only in black color
3:the sim slot is little difficult to insert sim
4:we have to slide the sim slot from the neck,not that much strong,while inserting sim we...
