Hi, **I bought an Iphone last month for my Mom's birthday. It was supposed to be GSM and CDMA unlocked. My mom lives in France and when she tried out her Sim card, it did not work. The screen says that the Sim card is not valid. I had bought another of these to my Dad last December, from Groupon, also unlocked, and it worked perfectly from France. I do not know what is wrong with this one. *Who should I get in touch with to fix this ? **Thanks very much in advance for your ***istance,*Best *Geoffrey
I trust that Groupon will make this right and come up with a resolution that is fair.
