I write this review after using E8231 for more than 4 months. Before this I used micromax mmx 219 w -WiFi dongle but I was disappointed with that product. After that I go through Huawei E8231 which work excellent for me.
The best thing about product
This is universal dongle so you can insert any sim card in this dongle
Connect upto 10 devices at a time
Download speed of Upto 21.6 Mbps/Upload Speed HSUPA upto 5.6 Mbps
Works with power mains/ laptop/ computer
No need of any APN setting just plug and play
Connect within 10-15 sec rather than micromax dongle which takes 2-3 mins to connect
SMS support- you can send and receive SMS
Huawei HiLink app for Android users. You can set password, read SMS, change your device name through this app
Both 2G and 3G sim support
The product work excellent. The WiFi hotspot coverage is also good. You can get the range upto 2-3 rooms in your house. The product lacks the feature of USSD support. Also the dongle doesn’t have memory card slot. But overall the product is best and I suggest everyone to go with this device. You can get this product online for between 1500-1700 rs. I recommend to go with Amazon.in as it has lower price than other merchants. To buy this product online please follow this link https://amzn.to/1U9cM9K
