What has been your experience with Spectrum Mobile?

I have the opportunity to sign up for Spectrum Mobile for free for a year since I’m an internet and TV customer. I’m thinking of taking this opportunity to save some money, especially because we had some unexpected vet bills that have hit us pretty hard. I’m also frustrated that my regular phone bill is as high as it is and T-Mobile can still spend millions on ads with popular celebrities.

I’m aware there are other options (US Mobile, Visible, Mint, etc), but I am asking about Spectrum specifically.
