Monthly data it's how much

I bought it 2 days ago, it's not deploying the daily 1.5gb as it should, and it's also displaying undefined

#fairusagepolicy #dataplan

Tell me the best data plane

Can a 5gig monthly data plan rollover a 7gig weekly bundle. My 7gig weekly data bundle will expire tomorrow I wish to buy a 5gig monthly data plan so can the rollover be possible?
