I have 2 phones. My primary phone with unlimited data is on AT&T. My spare phone is on Ting. The spare costs me about $7/mo since it's really just for emergency or privacy (it has the phone number I provide to travel companies and overseas trips and is kept on airplane mode with wifi most of the time). Since I also use DirecTV, the AT&T account gives me free access to HBO (which I don't use much) and HBOMax (which I am using sporadically). I expect it will get even more use if Crunchyroll is rolled into HBOMax as some media observers are predicting.

I used to enjoy the free use of AT&T wifi hotspots when I was traveling but I honestly haven't seen any of those in ages. Then again, I tend to turn wifi off when I'm away from home because I don't want my phone trying to bounce between wifi and 4G or to latch onto hotspots set up to sniff out your info. If I was trying to optimize my budget, I expect I could drop DirecTV, shift to a single phone on Ting (or even both phones on Ting), and subscribe to one or more streaming services and still save somewhere in the neighborhood of $70-100 per month. I haven't done this because I still enjoy DirecTV's variety of options and occasionally watching a movie on HBO or HBOMax and there was convenience (particularly when I was traveling a lot) in knowing I had unlimited bandwidth available via my phone.
