Guest pete.major Posted December 13, 2009 Report Share Posted December 13, 2009 Hi guys, I'm on O2. When I put in my SIM, the Acer seemed to set itself up so I didn't need to do anything APN etc. However, the voicemail is not setup. I googled o2 voicemail and the number is 901. I can call that and it works fine. But if I put 901 in Settings > Call Settings > Voicemail a message comes up with "call setting error - voicemail number change unsuccessful" Anyone have any advice on how to sort this out please? Thanks. Link to comment Share on other sites More sharing options...
