I currently use a Light Phone II through US Mobile. It’s not working out, however, because my phone randomly loses service and can’t access any of the data i’m paying for.
I’m trying to find another carrier that’s not super expensive, and it seems like my options are US Mobile (doesn’t work) or Tello (i don’t like their privacy policy).
Things like them having access to all details about my contacts, keystrokes and cursor movements on their site, tracking for ads, etc.
Are there any carriers with plans cheaper than LP’s $25/month that don’t do the above stuff that Tello does?
I’m also considering the Light Phone’s own plan, since it should definitely work with my phone. I’m just hesitant because it’s 2.5 times the price of my current plan.

You might want to look at Visible. The same as what you mentioned + mmW and unlimited throttled (10Mb) hotspot can be had for $35, with regular discounts for new users. It’s vzws in-house prepaid wing, alongside (seperate) their ‘vzw prepaid’ options (and of course Total Wireless, and Tracfone…).
I reluctantly have been a visible customer for 10 months now for my primary line - I strongly dislike vzw but that’s another story - and have been quite satisfied. Not as good as AT&T Small Business Elite, but it’s also a third of the price, so…
