Making phone calls in Taiwan

Chunghwa Telecom is the biggest telecom company. It is government owned, but efficient. It has a near monopoly in the landline business and is the largest mobile company as well. For mobile, Far Eastone and Taiwan Mobile are close competitors. Mobile services of all the 3 are good, but it may be useful to stick to Chunghwa if you plan to take a landline as a package deal might work better (eg - Chunghwa also provides home internet services with or without a landline and you can use the same connection on the move across the country through Chunghwa wifi hot spots free of additional cost). Pricing of all 3 operators is nearly equal. Telecom services are not exactly cheap in Taiwan. Tariff is around TWD 7-8 per minute for local calls, though there are many variations. ISD tariffs differ from country to country, but Skype/Viber paid services are strongly recommended v/s using the telecom operator.
