I just finished two weeks there. Upon arrival at Yangon Airport, I spent 1500 kyat for a SIM card, and another 12k kyat for 2gb of data. That’s just under $11 USD total.
Bring crisp hundreds - get them from the KTB branch (I think… purple signage) inside the BKK international terminal, and change to kyat right at Yangon airport. Kyat gets you a better deal and will be accepted without complaint even if they’re falling apart. Change them back at the airport on your way out.
Schwab worked at ATMs, though not until I called and re-added a travel notification. I found CC to rarely be accepted, and if accepted, with a 5% fee. Stayed in my wallet.
Wifi is painfully slow at the (mostly) 3-star hotels I stayed at in Yangon, Bagan, Mandalay, Hsipaw and Inle. Under 200kbps. I only used it overnight for larger downloaded and app updates.
One UK entrepreneur running an unscale pub in Nyaung Shwe told me he planned to get satellite in order to have decent bandwidth.
Agreed - I seemed to be blocked by the carrier for using my phone as a hotspot on iOS. FaceTime audio was reliable, but video quickly overwhelmed the mobile network.
Had 3G in all the cities, on top of temples in Bagan, for most of the train from Mandalay to Hsipaw, and even outside a monastery in a mountain village above Inle.
Hilariously, speedtests I ran throughout the country were always under 2Mbps and usually under 1Mbps… except at the aforementioned monastery - 7.8 up and 2.36 down!
Enjoy - I found it to be an awesome adventure and can’t wait to return.
