Questions about $25/month (8 GB data) ATT promo plan
I am planning to purchase the ATT 8 GB ($25 per month) promo plan from: https://www.att.com/prepaid/plans.html. I have a few questions around it:
1) Is the 8 GB data per month or for the entire 12 months?
2) I read that I will need to prepay $300 for 12 months to use this plan. What will happen after 1 year? Will the plan continue to be $25 per month?
3) Can this plan be used with my own unlocked iphone 6s plus and Samsung S8 phones?
4) When will be charged for $300, at the time of ordering the sim card or at the time of activation?
5) Do I have unlimited talk, text and 8 GB data when I am in Canada too with this plan? Will I be charged anything extra?
