Postal Service
In recent times, the Peruvian postal service has improved a great deal.   However, it can be more expensive than sending mail from a more developed country. Sending a letter from Peru to the U.S.A. may take from one to two weeks, depending on the city from which you mail it. The fastest service is from Lima. In most cities, post offices are open from 9 a.m. to 8 p.m. during weekdays, and half a day on Saturdays and Sundays.

Telephones
Peru's international code is 51.   There are public phones in Lima and the provinces from which you can make national and international calls, directly or through an operator.   Public phones accept coins or cards (obtainable from kiosks and stores). To make an international phone call from Peru, you have to dial 00, then the country code, the city code and finally the phone number. To make a national long distance call, you have to dial 0,l the city code and the phone number. Regarding mobile phones, coverage includes Lima and most provinces.

Internet Access
Peru has many public internet cabins. Most cities, no matter how small, will have one or more. Hotels and computer stores can offer help and information on places that offer this service. Don’t be surprised if the places offering internet are plain; only some of them are becoming cyber cafés and sell drinks or offer background music. Most of them are open until late, never all night long.
