There are two types of public phones: coined operated and card operated. If you plan to use an international calling card, you must insert a coin or card as temporary deposit. The deposit will automatically be refuned to you at the end of the call. Some of the public phones in airport or major hotels may take credit card.
Some of the card operated public phones required you to insert a special pre-paid card to dial.
Please note, not all card operated public phones accept calling card purchased outside Taiwan.
International roaming for mobile phones
Taiwan has a high-density mobile phone network in GSM 900/1800 standard. WCDMA 2100 is another useful standard but the total coverage is not as wide as the well-built GSM network.
To place calls to numbers outside of Taiwan, Penghu, Kinmen, and Matsu, dial international call prefix first, and the destination's country code, followed by area code and the local number.
Although there are many telephone companies offering international call service in Taiwan, the most common one is 009 (Chunghwa Telecom). Other prefixes include 006 (Taiwan Fixed Network), 007 (Sparq), and 005 (Asia Pacific Broadband Telecom).
To make domestic calls to any where inside greate Taipei area, you do not need an area code. If you are calling some one outside Taipei, you need the area code starts with 0.
Calling mobile phones
Some countries use the same system for land line and mobile phone system. Taiwan is using two different ones and all mobile phone number start with 09. When you call a mobile phone, the charge per minute is much higher than calling a land line number.
Some hotels may provide free internet connection service. Unless you could read Chinese interface, otherwise you may not be able to use Internet Cafe service.
Taipei enjoys citywide internet wireless access, including within its subway/metro system.
The postal service in Taiwan is extremely reliable. Post offices are open Monday through Friday from 8am to 5pm. Stamps may be purchased at any convenience store.
Mail collection boxes are painted either red or green and are roughly modeled after Japanese mailboxes. The red box is used for airmail and prompt delivery. The green box is used for local and islandwide mail. If the box is painted half red and green, put the islandwide mail in the green section and the airmail and prompt delivery mail in the red section.
