I’m sure you’re a tech genius . Please provide your proof that 3G is a significant cost factor in the continuum.
Kinda like landlines, broadcast Television and broadcast Radio. Not saying it isn’t a factor, but, your dismissal is not correct.
It’s called math. Each of the Gs runs on different infrastructure, using different frequencies. Funny you selected broadcast TV, remember the switch from analog to digital? Wasn’t that long ago. It was a SWITCH. Analog died. Too old, too crusty. Sometimes things have to move on. Also notice all those items you pointed to one company supports ONE item. Landlines are supported by the local phone company. TV network runs 1 broadcast in 1 region. Radio station runs 1 broadcast region. You want your cell company to run THREE infrastructures over the ENTIRE nation just you you don’t have to upgrade your phone.
Don’t need to be a genius at anything to understand this. It’s basic math. 4th graders can grasp this.
