Hello Ladipma,

From my experience, I would recommend you to go with Worldlink for reliability. The best part about Worldlink is its customer support. Its customer support is available 24/7 7 days a week and is pretty good. Literally, If you are having problem with internet connection you can call anytime in midnight too. And yes these, three ISP's are the oldest and finest we have in Nepal. ADSL is little cheap among two of ISP and also youtube is much faster, but since it is a government organization, customer support sucks. In Subisu, you will get TV cable with internet connection, but heard that customer support is not very good. I have been using Worldlink since 2011 and pretty satisfied with their internet connection and support. This recommendation is for cable internet connection. If Worldlink and Subisu does not cover your location, go with ADSL. If ADSL too not good for your situation, the go for Broadlink wireless internet connection.
