Ques. Can zte 3633 be connected with a TP LINK TP-MR3420 router...i need your advice??
Yes you can use zte 3633 along with TP LINK TP-MR3420 router.
The TL-MR3420 3G/4G Wireless N Router allows users to share a 3G/4G mobile broadband connection with family and friends via wired or wireless connections. By connecting a 3G/4G USB modem to the routers, a Wi-Fi hotspot is instantly established, via which multiple devices can access the Internet and share data and applications wirelessly.
Just plug the zte 3633 in the usb port of the modem and enjoy the internet.
zte 3633 can also be used separately as it has built in Wifi . So if you are travelling and you want to create a mini wifi hub, this device will always come in handy.
