While you are a way from your home town, you need deliver massage to your, family, friend and relatives. Email, telephone and post office are main means for communication. Trekking in Nepal often involves travelling to the remote countryside, where internet and phone services are extremely limited. Treks often take longer than expected by several days, so your family and friends often become worried if they don’t hear from you when expected.
Every main city has internet access either in hotels or internet cafes or your cell phone. Except remote places, there are internet services available most of popular teahouse trekking routes; Everest, Annapurna, Manaslu, Mustang, Langtang etc. Part of Annapurna, Everest and Manaslu tea house has free or paid Wi-Fi services. But you cannot accept very fast speed connection. You are unlikely to find the internet, though at places like Dolpo, Rolwaling, Kanchenjungha, Rara, Simikot, Makalu etc. You can access the internet (satellite connection) except high cost.
International calls can be made from nearly all the cities you are likely to visit except for when you’re trekking or any other adventure activities in the remote regions. In Kathmandu and Pokhara, there are many ‘communication centers’ where you can call, send faxes and emails. A few places have internet phone services that are much cheaper with good speed.
Now a day’s mobile phone services is available in the city and villages also but sometimes it is inconsistent coverage especially in the hilly and mountainous areas, the network is overloaded, so it’s often very difficult to get through.
It is easy to get a Nepali SIM card in Kathmandu or Pokhara or any other city with a photocopy of your passport and two passport photos. However the cell phone coverage is poor in many of the areas where you might go trekking. Even traveling Kathmandu to Pokhara on the Prithabi High way, there are many areas where there’s no signals.
Some international phone companies have Global roaming agreements exist. Check with your provider before leaving home if you wish to access roaming.
Receiving post is not convenient as you are normally doing something or traveling during the opening hours of most post offices.
When posting mail to international addresses, it is best to leave your mail at the post office rather than in a post box. In Kathmandu, some bookshops sell stamps and will take your post to the post office for you. Most hotels, trekking and travel agency can also help you post your mail. It takes quite long get post in your address. This is only formal to send massage or remember to someone while traveling rather than right information in time.
