When I ordered two Gizmo 3 watches on the website last week, I was able to pick the first 6 digits of each of the mobile numbers. I assigned them the same first 6 digits to make them easier to remember. Well the watches arrived today and neither of them have the correct first 6 digits that I picked, and they don't even have the same first 6 digits as each other. The website is not very helpful and is only allowing me to change the mobile number of one of the watches, and gives me only 1 option of first 6 digits (which does not match the other). How can I get these to have the same first 6 digits?
