Phone works in the US

For the first time, and on my 20th trip to the US, my mobile phone works in this country. Woohoo! 19 of the 20 trips have occured in the last 10 years, which also about how long I have used a mobile phone. In that time, my phone has never worked here. India, UK, Singapore, NZ, Thailand – all OK. USA, no. I can even SMS!
