How much is a phone bill for IPhone 8?

Probably like $500

This depends on the package that you bought, and not the type of phone you have. I have a pre-paid plan and only pay a minimum of $20 a month. If you get a pay as you go plan, you could be paying $50+ a month. I always choose a pre-paid plan a) because it is precisely what I want (I only use my phone for calls and texts), and b) it's considerably cheaper.

Depends on your carrier

It will vary according to the service plan you have.

Ask your carrier. No one else can answer your question.
