I'm traveling to the UK in the near future and it never occurred to me until today that there may be roaming charges or network incompatibilities etc. with trying to use my US-based AT&T iPhone 5 in the UK.
I haven't traveled in years and I'm curious to know if technology still has these limitations or is using my cell in a foreign country still complicated?
What is the alternative? Will I need to buy a temporary disposable phone or can a simple sim card swap do the trick? I could just go without a phone, but it might be nice to have in a pinch, especially if I wind up lost or in trouble.
