No I didnt have any problems but, there are two models available - the International and the Chinese. The Chinese one is a bit harder to gert hold of, you will need to get an invite (google it). For the price their phones are pretty good comparing to the other phones on the market.
anyways,we shall be making more visits to the gobbins,so if anyone is making visits themselves drop me a message oh and just while im here,anyone getting trouble trying to gert hold of lugworm? if so,i know a brilliant spot from where to get them from,just need a decent day and the tide to be right out.
