Have a question..

Currently im using maxis wifigo.. With mr600..

But with cellmapper, i can see that my coverage is best under yes 4g band 38/40..maxis tower is abit far.. But okaaayy laa sometimes the speed is 50mbps,most of the time is 10~20mbps

Question is, if say i want to change the band in my mr600, using the custom firmware.. To lock to band 40 ~ as the coverage is 'green' in my area/but its yes 4g tower laa.. Will the maxis sim connect to this band? Or will the sim only connect to band 3/7 because it is a maxis sim?

Asking this before i want to do any changes to my router firmware.. Hehe..
