In my latest bill, there is a charge for Int Txt to this number, +447786205094. I called Vdfn customer service, and they advised it's been charged by Facetime or iMessage for activated. It is strange cause my Facetime or iMessage already been used on my iPhone 5. Will it be continuous charge for future use of Facetime or iMessage? By the way, is there any other way to activate Facetime or iMessage, such as on the website? Anyone can help, thanks!
