Is it too much that I have two iPhones in service on truly unlimited plans.. one AT&T one Verizon? I do use both of them all the time.?

It may depend on why such as you use one for personal and one for business. 

I currently have 2 Moto G7 with Google Fi mainly I use them to play both Pokemon Go accounts at one time but my original intent was have one replace the home phone and to loan if family visits who don't have a phone or one that works affordably in the USA. 

I am guessing you keep both because you can only get "unlimited" plans now that are not actually unlimited. 

Too much for what? You're not the first, nor the last person to have more than one cellphone on more than one carrier, both with unlimited plans, either for personal use on all the phones, one or more phones for business, and one for personal use.

I see this a lot with friends/family that have business/family interests, in other countries. 

But it is rare to hear people bring it up, seek opinions on if it seems too much. It's one of the reasons many carriers outside of the use offer dual SIM phones. That way you don't have to juggle phones.
