What is difference between Data pack and data addons

[Threeukarn]

I want to know if i had to use my three sim for next month upon completion of my current one month pack , which data pack or data addon is to be top up so i would be able to get data for next month

A data pack is your monthly data allowance which you buy with your top up. A data add on is what you’d buy at extra cost if your monthly allowance runs out to see you through until you apply your monthly top up again. It’s probably best to buy a larger data pack with your monthly top up than you think you might need,that way it works out cheaper.

Spot on @Paddiewack. Data Packs include calls and texts as well as the data, and a data add on, is something you can "add on" if your data pack allowance has ran out before the pack expires.
