I was on Sprints free one year…for 11 months. Then switched to RW cause of the low cost. And because Tmobile network is just the best imo. Where I live, Sprint’s network is very good, in 98% of the locations I go to or tested in. LTE speeds even were much higher than Tmobile was in some spots. But LTE quality or speed was not an issue…it was how Sprint severely throttled things that killed my ability to use thier network, AND the Unlimited data. My home media server/DVR, Emby (alike to Plex) they considered on network end music stream and clamped a speed cap of 1megs, making streaming videos impossible. I had unlimited data, but no was to use it…Also, no VOLTE, LTE data while on call, no VVM…but hey, it was “free” for the year, well like $3 a month cause of taxes.
I have no intent to ever use Sprint again.
