I have a pre-paid gold plan with manual top-up, sim-only.
I also have a UK iPhone 5 (so the GSM ranges may not be quite the same as the USA models of iPhone 5 - I'll check the bands on another question).
The main question is - can I, or how can I, convert some of my pre-paid balance to use for data while I'm visiting the USA? (Currently I'm using them for voice/SMS only, but would like to have the option to use data too on occasions).
Thanks!
