I have T-Mobile One Plus on my phone, which provides more than enough high-speed data for my monthly tethering needs. Saves me the $150 investment and $20/month charge to just get the WiFi model and tether when necessary. I did get the LTE model when I bought the 9.7” Pro, but that’s when T-Mobile had 200MB of free monthly tablet data. Don’t think I ever utilized it for more than that.
