Nepal has advanced very fast in the field of communication. Internet, email and mobile phone services are available in all Nepali cities and along most of the famous trekking routes such as Everest, Annapurna and Langtang. Internet facilities are also available in those areas. However, services may be limited and the quality of signal unreliable. Sometimes, when trying to contact a phone in Nepal, you may be told that the person is unavailable or that the mobile is switched off. We recommend you try a few times, as these messages are usually due to network problems.
In Nepal, two companies provide good telecommunication services (links to the websites have been included below). New SIM cards can be used with any unlocked mobile device. Upon arrival at Tribhuvan International Airport, you can easily buy SIM cards upon filling out an application form, providing one colour passport-sized photo and a copy of your passport. New SIMS generally cost NPR 100, and you can top up your balance as per your requirements. The SIMS are activated instantly. Should you be unable to get a new SIM card at the airport, there are many retail stores downtown and in Thamel where you can get one.
