Pros:
Comparing to the leading provider in the U.S. I can say that the price of the plan is fair and somehow still on the bracket of their charges.
No need for you to change sim cards that allow roaming capabilities because there's no need for that anymore by subscribing to this plan.
Each GB consumed is for $10 and if incase that the person exceeded to 6GB then every usages will be free already. Due to bill protection.
Cons:I don't see any.
