monthly data question

I don't know about you, but I know with my carrier it's the 28th of every month.

 

What carrier?

Without knowing that we're just guessing.

If it is AT&T then they do it based on your bill. My info currently says I have 28 days left untill my next Bill on 8/5/11. But it'll be different for everyone.

Get the "myAT&T" app from the appstore and log in to your account with it. It will tell you how much you've used and how long you have left.

 

for ATT

Your renewal date will be determined by the date you sign the contract. If you are adding to an existing account, it will be the renewal date of that contract and your 1st month will be prorated.

 

It is going to be based on your billing cycle date. Those tend to be spread out over the course of a month.
Your first month bill tends to be for a shorter time span as they are going to put you somewhere in the billing cycle to balance out their cash flow. So your first month bill could be anywhere from 1 day to a full month. It is pro rated and they tend to give you extra minutes and data but only charge you for the prorated amount for the month.

 

Does Verizon have an app like that AT&T one? I would love something like that.

 

Yes, and it's called.... "My Verizon Mobile"
