I can recall the astronomical ARPUs in Afghanistan (over USD 80/month) when that market was opened up. Then, after normal Afghans who were not earning expat salaries started using the service, the ARPUs came down to more normal levels. There are plenty of expats roaming the streets of Yangon, but they have no discernible impact in the fast-expanding networks of this country of 50 million plus. But the ARPUs are high. We can confirm this from the sample survey we conducted in Feb-Mar 2015.
