USA Add Ons - 4G Coverage?

[MB01]

Hello Community: Last year I went to the USA with an add on based on my 3G plan, and coverage was very poor. Public Mobile does advise that 3G is becoming unsupported in the USA, so this is fair.

What I want to check with the community is that if I upgrade to a 4G plan, will the USA add ons actually work?  They are based on AT&T and T-Mobile, so it should be very good. However, I want to check before I do this.

It is very unfortunate that Public Mobile does not support e-SIM. Last year my work around was to buy a Google Fi SIM in the USA, which worked very well, but you need an actual US address to register.

Service will work in the US regardless of plan, somewhat spotty however. It will use whatever it can find of the 2G network for calling and use the 4G network for data. VoLTE has just started rolling out so you will soon be able to use that in the US as well. To reiterate, it doesn't matter if you have a "3G" or "4G" plan you use the same networks.
