- Health: Mobile handsets emit powerful electromagnetic waves which are absorbed by our brains. It is still not clear what are the health implications of this kind of radiation, but many people believe that there are significant risks involved, especially for children. Fixed line phones are virtually radiation-free.
- Money: The monthly service charge for a fixed line is Nu 100, but this includes Nu 100 worth of free calls. So if you're not taking advantage of your free calls, you're throwing away 3 momo plates' worth of money every month.
- Tariff: If I got it right, local calls (within the same area code) are terribly cheap (Nu 0.6/minute). Calls to different Dzongkhangs (Nu 3.5), and calls to mobile phones (Nu 3/minute) are much more expensive. So if you're calling a mobile number or a different Dzongkhag, it will probably be cheaper to use your mobile handset, but remember: you might be paying with your health.
- Internet: To connect to the Internet from home, you'll need either dial-up or broadband Internet. You will need a fixed line for either. (Broadband has two advantages over dial-up: It is much speedier, and you can keep making and receiving calls while surfing the Internet).
- Fax: This probably affects only a small number of people, but still... to send or receive a facsimile, you will need a fixed line (and a fax machine, but that's a different story).
Last but not least, there are a few "secret" features that are available with your fixed line. More information in an upcoming post.
