As per my knowledge, only Huawei & Intex has 3G modem cum Router available in market.
Currently I have Huawei 3G modem (e303C-2012Model) & I'm still using it without a single Issue.
That's Y I want to change the Brand. So option left Intex and Dlink.
Consulted With Bapun bro for Intex but later decided to go 4 DLink by seeing Reviews.
When I had BSNL Broadband(2010-2012) ,I Used TP- link Router. so I go for Dlink This time.
