Google Fi sounds awesome and I wish I could get it ...but I have since moved out of the US so I'm out of the service (Fi does provide great roaming service worldwide but I don't think they like it if you are ~100% outside the US. We use Google Voice voip and can use this on our cells phones via wifi.)
Google Fi provides a package for voice, text, and data at a good price...starting at around $20 a month, plus more for additional data.
Tello provides even more flexibility in that you can have plans with data (even data-only) or very low priced plans without data. For example, today (6-18-2022) the lowest cost Tello plan is $5 a month (plus any taxes) for 100 minutes voice and free texts.
Such a low-cost plan is good for those with limited funds or limited need for a cell phone...maybe it's for emergencies only, no need for web access (I have to say, web access is great when shopping...compare prices, see who has it in stock, find what aisle and bin it is located in the store!).
Note: You don't need to buy a "Tello" phone. You can use any compatible cell phone hardware. In fact, you can make calls with Tello using a wifi connection....these are unlimited.
