Thanks for the advice but I have enough trouble operating one sim, so have plumed for the www.piranha-mobile.com option that will hopefully be with me tomorrow. They have explained to me how to setup voip that I can use over the internet. I am off to Canada for a few days next week so will be able to see how I get on. I have also purchased a blaze phone for £60 that is unlocked for the job. Shame about my iPhone as it was an expensive purchase and it seems that it can’t be unlocked until my orange contract is up.
