Huawei E303C Works Like Magic For 3G

Bought this on 12-Feb-2013 from nehru place, as I had some work there. Price the same as here if packaging and home delivery are taken into account!

good product...

1) Sim insertion/removal is very easy
2) Software installation takes little bit extra time but for once only after this simply insert sim, it will detect automatically and show network bar with service provider and connect to go on the air.
3) Not a single disconnection till now as it may happen in other data cards (I am using 2g aircel unlimited data pack and getting download speed of 20-25 KBPS (not kbps) average)
4) No configuration setting to be needed, detect sim and connects automatically. No manual setting needed. (remember some data cards may require complex manual setting each t

very good product.
with bsnl 2g sim card it gives a "browsing speed" > 250 kbps constantly under wcdma as n/w settings. i have downloaded a 35mb video within 6 min so you can guess the "download speed"!!!!!!!!!!.
works good with all n/w's . For bsnl alone you need to configure apn details . Apn details

Best Product with respect to other Data Cards

First off all i would like to inform all users that there is no problem at all with BSNL sim card in this Data card.


1.) Works like a charm with D/L speed near about 3.4 with Vodafone and BSNL 3G.
2.) Windows detects it as a Mobile Broadband 3G Card Network Adaptor.(i. e. You can use this right from your Taskbar even if Modem Dash board is not opened, which is not available in other Modems in the Market)
3.) Beautiful Dash Board Software with Various Skins.
4.) And the Most Important thing is It Also Supports USSD featute along with Calling function.


I coulsn't find anythin

Good Data Card

I ordered this Data Card on Thursday and got the delivery on Monday, I guess, that is probably because Sunday was a holiday, or would have got it by Sunday. Hence, from delivery point of view, this time Flipkart was a bit slow, as I am staying in Chennai and every time i purchase from flipkart, I get the delivery in 2 days.
I tested the data card with 3G as well as 2G SIM. Speed and performance is as follows,

Location- Chennai

3G- Speed

Aircel - 3.5 Mbps( I was using a plan whose speed was limited to 3.6 Mbps)

Idea - 6.5 Mbps

BSNL- 3.4 Mbps

Airtel- 4.6 Mbps.

3G connectivity was good wi

I'm using this product and presently this is a better option as compared to Micromax 353C. The only reason behind that is the Wi-Fi Hotspot upgrade software (which you have to download separately from . Great product, nice interface. Remember, while connecting internet via wi-fo hotspot do no forget to keep the LAN settings as "Automatic" in paired and pairing devices. Have a good time :)

freedom from monthly bills


I have been using TATA PHOTON for my internet needs, the monthly cost would come around rs.850/- !!!

I heard about this product and added it to my wishlist. I was apprehensive to buy it earlier because i was not sure if SIM removal/adding and programming would be easy. So i just postponed the whole idea.

Then my photon was borrowed by sister, and i had to search for alternative internet; i came back to Flipkart and saw the 200+ good reviews and thought i'd give it a try, Product arrived within 2 days.

Installation was a piece of cake.
SIM card insertion is easy.

SPEED : I am

good but not upto the mark

I am using this product last 3 days .My experiance is not so much pleasent,there are some pros and cons of huawei e303c dongle

1> The product is very small and designed well.the most beautiful thing that , just open the front cover by sliding and set your sim, which is very easy.
2> Huawei software is great,it automatically installed within 30 -40 seconds and starts working
3> The product speed i have checked so far is that on aircel 3 g almost 500kbp/s ( after complete of the 1 gb 3g pack).

mmx 353g vs huawei e303c

After going all through this it is quite evident that the mmx353g has some sim insertion issues. moreover Huawei has a strong body with 32gb expandable micro sd. Moreover e303c tends to increase the internet speed to quite an extend. So guys i have decided to go for Huawei as it seems to be the winner among the two. And lets not forget India's 60-70% data cards are supplied by Huawei. So we can clearly see the winner.
