Do not get an iPhone on the orange network. The network is simply not able to deal with the demands of the iPhone. Apparently the iPhone uses 4 cells compared with other phones that only use one cell. Upshot is that iPhone users regularly get bumped to another mast or lose coverage altogether. Orange are also in the process of completing their merger with t-mobile but this won't be finished until next year. Also visual voicemail does not work on orange.
