if get your question right, you need a data plan depending on you device and also on the plan you chose.. all smartphones require a data plan or an Everything data plan. review what you use your phone for and how many lines you have. if just 1 line and you use your phone a lot (data, text and talk) everything data 450 would be the best for you. if more than one line and same usage, the plan would be everything data share 1500/3000. there are many plans depending on your needs.
