Jetpac solved my problem despite my difficulties.
I contacted JetPac because it wasn’t working correctly. The help I received was quite complex and involved and I must say that Pau was very patient and attentive with me especially as I was on the move while trying to implement the changes he was asking me to do. In the end everything worked as it should despite my difficulties but the patience shown was very much appreciated. I will use JetPac on all my trips from now and recommend them to anyone travelling to foreign climes especially China where I am moving around.
