I'm having one heck of a time trying to activate a 5g moto mod. I already have a 5g unlimited plan, and when I click the thing on a moto z4 the auto activation fails every time. Verizon tech support is totally useless, heck I never spoke to a single person that knew what a moto mod was or that it had a sim card. I did get a help ticket put in once I had spoken with 6 different tech support reps.
When attaching the mod it does bring up a up sale page in web browser, but there's no way to do anything from there, and it dead ends you after entering account info.
I'm about to give up and just return the mod and forget about it.
