Huawei E3121 Data Card Review

Mobile Broadband came into existence with the introduction of data cards by operators like Tata Telecommunications,Reliance, Airtel and Idea in early days.Photon,Net connect and Netsetter are the data cards offered by these players which provided people to access internet on the move.With the introduction of 3G services in India more players involved into this business.Basically a data card can be classified as two types GSM and CDMA. These data cards that are bundled with the ISP/Telecom Company is locked to the operator and hence came the need for unlocked data cards/dongles/usb modems.Thus it made a few companies bring operator free/unlocked modems/data cards. The main advantage of this type of data cards usage is the freedom to choose the operator/sim.Thus providing the flexibility to move between operators for better signal,speed,reliability,cost and features.

Currently Huawei,Micromax,ZTE,Beetel,Alcatel,Teracom,LAVA,Intex,Lexosys are some prominent manufacturers offering the unlocked data cards to the customers.
When it comes to unlocked data cards customers are now preferring company unlocked data cards to manual unlocked operator bundled data cards,the reason behind this is the company unlocked data cards come with original warranty,software and support.Moreover they are cheap and affordable.
Huawei Data cards are chosen by large amount of people as they are reliable,better performance,features,affordable and ease of use.

Huawei E3131 is at the higher end giving up to 21.6 Mbps download speed where as Huawei E3121 is in the mid range with download speeds up to 14.4 Mbps.Huawei E303C being the lower end of the range with speeds of 7.2 Mbps.In this Huawei E3121 Data Card Review you will find everything you should know before purchasing it,as we have used it personally before actually writing this review.

Soft Wi-Fi: This is an additional feature offered by huawei Mobile partner Software.Managed mode and Adhoc mode are the two ways in which it works.
In Managed mode it gives Full support that means the data card gives soft wifi functionality (hotspot) to connect with other pc’s/laptops/other devices.This hotspot supports up to 5 wi fi connections.The range of the wifi signal depends upon the hardware of your laptop/desktop wireless lan card.It is possible to connect with your Android devices, Blackberry devices, Amazon Kindles,I pads,I phones,Smart phone’s etc,. in this managed mode.Managed mode is supported on windows 7 sp1 onwards.

In Adhoc mode it supports  1-2 pc’s/laptops connections only. This mode will work on Windows XP and Vista versions. The Soft wif-fi feature is software based and hence Mac and Linux os won’t support this feature.Basically Adhoc networks can be created on any wifi cards with its default software even to make a wireless lan to share files and stream music/videos.
In order to enable soft wi-fi it is required that you already have an internal wireless card/external wi-fi adapter connected to your computer and working.
Huawei e3121 review                                                         
Design: The data card  design is sleek,compact and stylish.The white color of the data card gives it a premium look with huawei logo printed on its cover on both sides.Inserting and removal of sim card is easy to use,however we recommend you to stick to a good operator in your area after some testing for signal strength,speed and costs.Thus preventing the wear and tear to the sim slot which generally happens with frequent removal and insertion with any device.
The plastic used is smooth and is of good quality.The micro sd card slot is beneath the sim card slot which is very good as it doesn’t interrupt the sim/sim card slot during insertion/removal of sim.The usb port is solid and good. The data card also provides a small ring at the usb port input end which can be used to tag a data card holder.The cover can be slide downwards and it is easy to remove and use.

The interface is simple and ease of use loaded with features.Whether you want to make a voice call/send a message/check balance/ connect to internet.Everything is clear and straight forward.The mobile partner also has features to call/sms/email huawei support.Huawei E3121 data card automatically registers your data card warranty by sending an sms from your dongle when connect the data card for the first time.The huawei zone is loaded with a landing page which gives freebies worth Rs 6000/- includes 3 month kaspersky anti virus software download,AVG Internet security with license for 1 Year,nexGTv Iptv 60 free channels subscription for 3 months,Unlimited movies from BIGFLIX for one month,up to rs 200 OFF from homeshop18,5% off on carzeal on all deals,Freecharge recharge coupons etc..

Huawei E3121 Mobile Partner Dailer
This the dialer software which can be used to make voice calls.The keypad can be used by mouse clicks or by inputting from keyboard.We can also select the stored contact from contact list to make voice calls.
The voice calls made from our PC are clear and noise free,all you need to do is a purchase a quality headset to use this voice calling feature.There are no disconnections and disturbances experienced in any voice call in our testing.
The dialer displays the call duration once the call is connected. Moreover this is very useful for people who talk hours on their mobile,as it emits less radiation when compared to direct calling from mobiles.

Huawei E3121 Hands on Review
Hands on review Huawei E3121 data cardSpeed Test Results for Huawei E3121 Data Card for Aircel Network.
Speedtest test results huawei e3121 aircel
We tested the data card with the least/starter data plans on Aircel and Airtel networks at our place during the peak hours on 3G Network,the screenshot shows the result of the speed offered by the isp at our place.
 Speedtest results offered by huawei e3121 on airtel
The speed test results shown here are for 3.6 Mbps connection/data plan subscribed by us at our place.The data card can offer amazing speeds provided that ISP signal strength,number of users accessing the tower,Time of use are optimal.
The signal strength and speed offered by this data card out numbered our mobile phone.The presence of type 3i and Rx diversity is clearly seen.  Update:  We have tested Huawei E3121 Data Card with Datawind UbiSlate 7C+ (Edge) with usb connector and it worked fine on 3G and 2G networks.We will be posting pictures of the same soon here. The tablet we tested runs on Android 4.0.3 (Ice Cream Sandwich)
Verdict: This is the best data card in terms of cost,ease of use and features in the segment (14.4 Mbps) data cards available in India. The data card showed good performance and reliability during our testing on 3G network.The data card didn’t faced any automatic disconnections with the networks we have tested in our area.We continuously used the data card for 3 hrs on 3G network without any disconnections/interruptions.Although the usb external data cable and external antenna are not present we don’t faced any performance lack.As reviews said that the initialization of data card took time for the first time,we actually didn’t faced anything like that.May be the people who faced those slow initialization were either using slow/low end system/running a lot of application in the background.We tested the device on Windows 7 SP1 64 bit professional edition on 64 bit asus cpu which showed good results.We can’t comment on soft wi fi as our pc is not equipped with a internal/external wi fi card.Finally if you are a person on the move/need a cheap broadband alternative/mobile broadband/flexibility in choosing own operator/heavy surfer/downloader/casual user/professional who need to work on the move/student who need to use internet from mobile phone/data plans this data card is for you.

We can say that it will fulfil your needs and it will be in your budget.The only feature we expect in this data card is the ability to use connected video device/web cam/mobile phone cam to make video calls.Hope Huawei will upgrade such features on its mobile partner software in the coming days.Just go for it,buy it.
