There are many internet cafes liberally scattered around the city and they cost around t400-800 per hour.
The central post office is located on the south west corner of sukhbaatar square, and besides stamps it also sells a wide variety of reasonably priced postcards though they may take up to two months to reach their destination!, some very large, decorative collections of stamps which are not for use and a few nice calendars.
Telephone
The city has an international call center. however, if you have access to a private phone, the most convenient way to make an international call is to use a prepaid card, such as bodicom.
Cell phone operators offer both prepaid GSM sim cards and handset rentals Currently Mobicom as well as extensive roaming options for your convenience.
UB has a high crime rate which explains all the steel bars and security guards in apartment buildings and larger stores. Pickpocketing is common and violent muggings are increasing so it is advisable to avoid walking alone after dark. Street lighting is unreliable and the city is frequented by drunks and stray dogs. The places where pickpocketing is the most frequent are buses and the Sunny-Tuul market alias Naran-Tuul market, or Black market, specially the entrances of them. The bus stops close to the State department stores are hot spots for this activity. If you've been attacked or pick-pocketed, please take time to make a deposition at the district police station, and to say it to your embassy if you have one.Most sidewalks are not paved and so can be very muddy and slippery during a thaw or after rain. Walking on the streets at any time is a hazardous affair as one needs to contend with ice from about October to March, open manholes and extremely chaotic and wild driving habits. Drivers including buses and police pay no attention to pedestrian crossings and will not reduce speed, but simply sound their horns. The automobile culture in this city is too new to have developed safe driving systems and habits.
Unmarked taxis are common and shouldn't be feared. Locals simply stick out an arm and hitchhike anywhere around town. However, it is wise to get a local to interpret if possible and explain the fare system.
Child beggars are common and persistent on the streets, but watch out for groups of them, as one may be trying to pick your pocket. Also be aware that any money you do donate will go straight to their teenage "pimps", and so you may not be helping them as much as you think. Most of the "pimps" are their relatives or friends and the kids actually come from poor families and it does help them.
Walking at night in company shouldn't be too great of a concern, it isn't for the locals. But stick to areas where you can see lots of locals especially women. Coming out of Bars late at night is a little dangerous if you are alone, try to have several males in your group.
