In all the areas that foreigners are allowed to visit, Myanmar is very safe in terms of personal security: incidents of crime against foreigners are extremely low and Yangon is considered to be one of Asia’s safest large cities, with no areas that need to be avoided.
You may sometimes be approached by ‘money changers’ and people trying to sell things (their statements should not always be taken at face value), but this will usually be done in a good-natured manner. In fact, you will often find that people approaching you simply want to take the opportunity to talk to a foreigner and maybe practise their English.
For many years SIM cards in Myanmar were expensive and difficult to obtain, but cards sold by the Telenor, Ooredoo and MPT (Myanmar Post & Telecommunications) networks are now generally available for a cheap K1,500. Cards work on a top-up basis, with K1000, K3000, K5000 and K10,000 cards available.
Ooredoo and Telenor became operational in 2014 and networks offer 4G coverage. SIM cards and top-ups can be bought at numerous street-side retailers in downtown Yangon and Mandalay, as well as at Yangon International Airport and in most larger towns, cities and tourist sites.
To purchase a SIM card, foreigners need to have photocopies of their passport photo page and Myanmar visa page, as well as one passport photo. SIM cards are 3G mobile data enabled and standard SIM and micro SIM cards are available.
International roaming with an increasing number of foreign mobile networks is now possible in Myanmar; the situation is changing fast, so it is best to check with your operator. You may encounter a block on data usage or SMS text messaging even if you are able to make and receive calls, and if this is the case you should go to a licensed Telenor, Ooredoo or MPT shop for advice (there are many in the downtown areas of larger cities).
