I’ve been using Page Plus for about 5 years. Outside of their ridiculously slow-loading member pages, I had no issues. Actually, I think I started out with 2GB or 3GB of LTE data per month and ended at 8GB per month for the same price — that part was solid. However, I was moving on from using a series of cheap LG G3s then LG G4s ($60 or so on eBay) to a LG V30, and I was concerned I’d lose my hotspot with foxfi / pdanet. Which, to confirm: you can use FoxFi with a non-root LG G4 with Page Plus. I assume any other carrier that doesn’t offer a mobile hotspot by default as well.
