MTN ZERO SERVICE - NORTHERN AREAS

whenever there is loadshedding i have ZERO internet access in depsite having data , airtime and everything. Whenever there is loadshedding i have zero internet access in the NORTHERN AREAS so i can't attened my online lectures and end up missing out. However when i was in the suburbs this past weekend i had internet access while loadshedding so that tells me that there's no towers and internet access in the northern areas or well not enough coverage which is very disappointing!
