I've recently been using a friend's MTN 4G wifi router, which has been working quite well.
However, I'd like to get something smaller that would still be universal.
By smaller, I mean something which is not quite expensive and pocket friendly to use for the main time before I embark on getting anything stronger.
I searched on Jumia and found this product (Link Below) and I simply want reviews from those who have used it before. Will it work for what I intend to use it for. I need it as a wifi router which would work for any sim and not necessary as a USB modem.

Feel free to give your own suggestions. It will be very appreciated.
