I'm going to Indonesia next week to meet my girlfriend. I normally use a Virgin mobile phone but last time I went, I had no coverage so I couldn't contact her at the airport and had to borrow a phone from some guy who worked at the airport. So I tried to find out any companies where I can get a sim card that will work in Indonesia, so I can text her to make sure we know where we are meeting. I've read that Orange and Vodafone have Indonesian coverage, can anybody confirm this? Or tell me any other sim cards that I could get in the UK, which can be used in Indonesia.

Thanks!
