Worked great!

I traveled to England and Spain in October. I bought a Three card for the first time. It went all very smoothly. Activation of the card in the USA took about two hours and when I had a little problem with the app I called customer service and they resolved the problem immediately. I had no trouble while in Europe whether I was in Spain or England. The only reason why I gave only four stars is because when I tried to make phone calls to the US I believed that I could use the credit that I had but I was not able to make phone calls. I did not have the time to talk to customer service so I just called the USA using WhatsApp.

Finally available for US!

It’s about time! I travel back and forth for work to the UK so I’ve had a Three SIM for a long time. Thank you for FINALLY making the app available to US users. Now if only you allow up to top up with a US credit card like EE does.
