Monthly data it's how much

I subscribed data for 53GB at 10,000 Naira. I want to share with a friend, but it's not permitting. How can I share data

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

I need multiple sims for a device that uses minimum amounts of data to stay connected to the internet. But i need these sims to always be connected so i can pay the owed amount...
