Built in vs. Stand-alone GPS?

Hmmm ... if an eSim card can be installed in an iPhone or an Android phone that ties one to a global service provider ... then:

1. Do you then get billed each month by the global service provider ... just like you would if you had a sim card locking your phone to one of the common U.S. providers?

2. If one uses their smartphone only in, say the U.S., but via a global service provider - then are you saying that wherever you are in the U.S. - your phone will connect to whatever specific U.S. providers' cell signal is the strongest at your particular location ... i.e. be it a Verizon tower, or an AT&T towers, or a SPRINT tower, etc. at the time?

If both the answer to both 1. and 2. above is "yes" ... then who are some 4G or LTE global providers that I could switch to, where can I find what plans they offer, and if there our some then WOW .... it seems like a no brainer to set up this kind of arrangement on my upcoming purchase of my first ever smartphone (to be Android based) so as to get best possible cellular signal coverage in the contiguous United States, Alaska, and Canada for RV travels?

(P.S. Unlimited and speed un-throttled from a global provider meeting the above requirements would be the ultimate - but that probably doesn't exist or is extremely expensive if it does exist.)

1. Yes, I get on bill each month.

2. Yes, my phone seeks out and jumps to the strongest signal, regardless of carrier. Every phone already jumps to the strongest signal, but only within the network it’s locked to, unless roaming. My phone is in a perpetual state of “roaming”.

I use GlobalSIM, I’m told there’s others, I just don’t know who they are. Global is the biggest.

It’s not expensive, I have 2 permanently assigned phone numbers (in my case one 416, one 305, both of which are always ‘live’) unlimited calling (no roaming charges, no long distance), texting and data (never throttled, no tethering restrictionists) almost anywhere in the world for $75 / month.

Thanks for your information follow-through .... I'm learning a lot, but it sure seems like a lot of research is going to be required if I want to break away from the comfort of good old Verizon (with it's expensive, limited full speed with unlimited data, good but not perfect, etc., coverage).

By the way, I notice that the GlobalSIM's coverage map seems to show vast areas of no coverage in Western U.S. places where we like to travel in our RV. Unless I'm interpreting the GlobalSIM's coverage map wrong - pure Verizon coverage my be better or at least easily equal GlobalSIM's coverage. I thought providers like GlobalSIM offered service that would jump between U.S. networks so as to automatically use the strongest signal ... hence easily providing service coverage well beyond what the Verizon-only coverage map shows?

Here's the GlobalSIM coverage map - which seems to show large poor/no coverage areas in the Western U.S.:
