First of all thanks to flipkart for its pretty service. I received product within 3 days of placing order in a well packed box.I had used cash on delivery mode.Some had complained that it not works with tata docomo cdma. Actually it is right. Because docomo has changed some technologies in cdma sim. But I am using it with docomo. If anyone has docomo sim manufactured in 6/11 or before,it will definetly work.But it works well with reliance and mts.The speed of net is far better than gsm 2g and...

stable with bsnl evdo connection.......better than prithvi bsnl evdo data card bcoz it doesn't support windows 8 single language...
concern-it doesn't have ussd and voice call facility
other than it is good and easy to use

Micromax has done a great job, very good product. Working fine with BSNL & Reliance RUIMs without any issue. It latches to network very quickly while locked devices on respective networks couldn't find any signal. Getting little warm if network strength is below average.

Flipkart promised to deliver in 6-8 working days but reached by door withing just 3 days. Great going Flipkart.

I am using BSNL EVDO. Good modem at reasonable price. Software installs automatically in Windows. No need of software in Linux. However it is bit more wide than needed. So if you have 2 usb slots side by side and if you put M 300C in one, the other slot remains unusable as Micromax 300C partially blocks the adjacent slot.

THOSE WHO WANT TO USE BSNL EVDO SERVICE. THEY SHOULD GO WITH THIS DATA CARD. THIS IS GENERALLY MEANT FOR CDMA NOT FOR GSM. WELL WE ALLL KNOW THAT 3G IS HERE BUT UNLTD PLAN IS NOT THERE. IN CDMA IN DIFFERENT U CAN GET UNLTD SERVICE IN EVDO.

I have recently purchased this data card from flipkart and used the device with TATADOCOMO and Reliance sim cards. The docomo sim card i was not able to connect to the internet and i was able to connect to the reliance. I have take the data card to to the micromax service center and poor responce from them and they does not know about the device.

This is yet another mediocre product from micromax. The case is big enough to hide the adjacent USB slot.
One more problem I faced was with the sms. I deleted all the sms using the "delete all" button. Later I am facing this problem "Unknown sms error. Please reinsert the device...".
I am not finding a solution to this problem at all. Reinstalled the setup, but to no avail.

Did anyone of you to face the same problem? Any solution? Please share.

lacks in os problem between cdma 1x and hsia change over mode.it is always needed to be used in automode...poor software.

as of now 3g is the best at high speeds..

it supports only 3.1 mbps.that too in rev.a technology
