My new phone number has only been connected to my home WIFI. Last night, I was finally able to activate my SIM on my new-to-me-phone, and activate my phone number. Why is it showing that there's already 6MB of data usage on my account?
My SIM is paid for and installed in my phone, but my iPhone 6S will not allow me to upgrade to a newer software version to allow install of the Public Mobile app... So how do I activate my SIM card?
