Taunggyi is a lovely place and it's one of the cleanest (and large) city in the country. There are a small town near Taunggyi called 'Kalaw' and it's be great if she could spend sometime there too. It's such a nice weather right now, too.
The change is very quick as you mentioned. The SIM cards became so cheap and the speed became much faster than before. So, even to local people like us, it's amazing.
