You are right--there are no ATMs.
I'd suggest bringing CRISP US$ with you--they may not take torn or even worn bills, and if they do take them they may give you less for them in exchange. If you are worried about carrying a lot of cash, try a money belt with large bills.
Also, be careful in exchanging money--the official exchange rates are a joke, so you will want to change on the black market--your hotel can probably change for you, and people in the markets, et cetera, may ask you if you need to change money also. almost 8 years ago
If you are not a fan of money belts then try putting your money in a soft sun glasses case/bag tied onto the top of your pants and then dropping it down your pants.
This trick saved me a lot of money when being basically robbed in South America, they didn't get our cards or our cash. almost 8 years ago
Take US Dollars cash but the lastest ones. Nothing torn or written on.
They don't always accept 100$ bills. Take smaller.
Traveller's cheques can be exchanged in major cities but at a very low exchange rate.
You cannot obtain cash from ATMs if you have an International Card.. almost 8 years ago
Just back from Myanmar. There are now ATM's fairly well distributed through Yangon and even in smaller towns. I had no trouble getting cash on my Canadian Bank account. More businesses are taking Visa and even a few are taking American Express. Cash should be carried in more remote areas. US currency is the preferred currency. Earlier advice was that the notes had to be clean and not creased or torn. This rule appears to be relaxed somewhat. I used an old and creased note at the airport cafe. over 4 years ago
