Am trying to set up an International Global Roaming package for an International vacation on iPhone 6 Plus and iPhone 6 using online services. When trying to sign up, it is asking for the Sim Card Number for each phone. It also said I could go into settings and type in the ICCID Number which is the same. After typing in this number the system is telling me that the SIM Card Number is not recognized. I popped out the SIM Card to make sure the number was correct. Any ideas why Verizon is not recognizing our SIM Card Numbers on phones that have been active for awhile now?
