You probably won’t need to buy another cellphone while you’re in Taiwan. Apply for a longer number, and you’re all set!
You can purchase a prepaid card, though you’ll need to top-it up (or buy more credit) every now and then. Otherwise, you can apply for a postpaid plan and pay a monthly fee.
You can purchase a prepaid card at any branch, or even at the airport. You may need to bring some form of identification with you, so you might want to bring at least two kinds of ID (passport, drivers license, ARC, etc.) just to be on the safe side. You can top up your prepaid card at convenience stores or at any branch of your preferred mobile provider.
- Chunghwa Telecom Prepaid SIM
- Taiwan Mobile: 3G Prepaid Card or 4G Prepaid Card
- FarEastTone Prepaid IF Card
- Two forms of ID: Passport and ARC/NHI Card
- Deposit payment
Some mobile providers require a Taiwanese national as a guarantor, so you might want to ask a local colleague to accompany you. Your guarantor must be 20 years or older, and should have two forms of ID with them.
