But in Vietnam with MobiFone, I had to charge the thing just about every night. It was annoying. Conversely, in Beijing with China Mobile, I barely had to charge it once a week.
This does speak to the relative power and density of the various installed networks. Or so I'm given to understand. I guess the Vietnamese can't afford more and higher-powered towers, and the Chinese must have towers blanketing the place. You really can get full signal just about anywhere; up on the mountain in Fragrant Hills park, down underground in the subway.
I mentioned this to alexinbeijing, and he talked about how in China you just don't get to object to cell towers the way you do in the States, and that people don't seem to care as much in any case. He gave a very amusing imitation of a Californian objecting to a tower going in nearby, delivered in a whining voice. He's from SF, and it was spot-on.
