Oh yes, I've been using these for years. Worse, I need one for each building just to get phone coverage inside, steel roofs don't help.
True enough. I recently returned from a 4 week trip to the EU. I picked up a cheap Vodafone SIM card in Barcelona, stuck it in my iPhone and had more than enough voice and data (100GB) with hotspot and roaming for about $40. I was all over Spain, southern France and the French alps and even though it was spotty in the alps the service was still comparable or better than what I get here.
Yes, the US is huge by comparison and once upon a time we were the envy of the world with our telecommunications system with probably billions of dollars of now obsolete copper buried in the ground. Now the telecoms must rely on tower coverage and the US is struggling to catch up with the infrastructure easily created by smaller, poorer countries who can more easily service their populations - quite a few of these countries in Asia, S America and Africa were able to completely skip the investment of time, labor and materials of a hardwired network.
