Can I add 1GB of Data to the $25 Plan for AT&T for an iPhone 5s?

The $25 prepaid plan is 250 minutes of calling & unlimited texting, but no data.

Can I add 1GB of Data for $10?
Like it says for other plans?

AT&T is the carrier.

You can't even add an iPhone to a prepaid plan, let alone 1GB for $10 on the $25/mo. Prepaid plan.

The $25/mo. Plan is $5 per 50MB. The 1GB for $10 is if you purchase the $60/mo. Prepaid plan.

  • Will getting the 1GB Data Share Plan the right choice for a iPhone with At&t? I was wondering is it a right decision to choose the 1GB data share plan, since there will be only one line on the account? I don't know if that will effect my speed or what, I'm just trying to choose the right plan for an iPhone that will be the only line.
  • Will 1GB of data a month be enough for an iPhone? I'm thinking of getting an iPhone, but only the small plan, which has only 1GB of data a month. The only thing I go on the internet for on my phone is Facebook. Will it be enough data? Or will it be constantly looking for updates and stuff and use internet data? My old phone did that and took away heaps.
