Those are country development and political choice issues. Last time I took the train (this weekend) it provided a free wifi access all long and I hadn't any cut. I can't remember last time I took a subway and hadn't 4G connectivity. Oh, actually I do, it was in Paris but I wouldn't dare using my iPhone there anyway. There technology is there but Western governments at all administrative levels are more busy bullying their citizens than providing comfort options like East-Asian administrations and companies are.
