If you're staying in the USA for longer than 30 days, you can:
(a) Top-up on the same plan; or
(b) Top-up on a different plan.
Also, it is not possible to recharge your plan just for a few days - you can only purchase another full 30 days of your plan.
So for example, if you're on the USA Canada and Mexico Extreme Plan, and you're in the USA for 35 days, you could:
(a) Top-up for another 30 days of the USA Canada and Mexico Extreme Plan (sorry, there's no way to recharge just a few days of that plan); or
(b) Top-up for the USA Max Plan.
To recharge simply go to www.usapayasyougosimcard.co.uk and follow the top-up instructions.
