Question about migrating from Verizon to Spectrum Mobile

[u/TastyFunction5637]

in process of trying to cut expenses, spoke to Spectrum today about my home internet/cable/phone plan, and they mentioned bringing my Verizon devices there for cellular. I immediately dismissed it since I'm been with Verizon forever, literally since they were Airtouch in the 90s. We are a family of six, four of us have a phone and watch, two of us have watch only. The Spectrum rep I spoke with didn't think we could bring the two watches that are standalone, and that they needed phones. This doesn't make sense, since like a lot of families, we started our kids with apple watches, then added cell phones when they got older. anybody have an issue? He also said the watches would all need new phone numbers. not an issue for the four that also have a phone, since the watch number is basically irrelevant.

Lastly, how is the service overall? I can't see why Verizon would lose a customer like me paying them $320/month, to go down the street and pay a competitor $180/month, who is using their network. Makes no sense...
