Lmao! Yeah, Verizon is pretty sneaky. Glad you called first. Supposedly, if the tiered line is eligible for an upgrade and you buy a subsidized phone, activate it on that tiered line, then you switch it to your unlimited line, it does not make your lose your unlimited. This scenario Verizon actually explained to me. But I understood it to be that the tiered line had to be eligible and he was very clear that the new phone had to be activated on the tiered line before moving it over to the unlimited line.
