What is the fatest Mobile Network for Browsing apart from MTN?

Please house, can anybody tell me the fastest Mobile Network for browsing apart from MTN that can be used on MTN Modem.

I have MTN modem and have unlocked it, I am using ZAIN sim, but not too fast.
Can Glo SIM or ETISALAT SIM be used on it?

MTN is sweeping the bundle like wind whenever you load 50MB bundle. In 10 minutes, they sweep the 50MB away.

I need your contribution

Anything from 100mb down is not advisable to be use on system. 100 & 50mb are made 4 phones not modems/computers!

Try glo, for #500 u get 150mb. D solution to d problem of 50mb in 10mins is to turn off ur auto updates especially dat of windows, dey usually exhaust such bundles without one knowing.
