Taiwan Mobile tourist SIMs range from NT$300-1,600 ($9.90-52.90) depending on validity period and network type. 4G plans start at NT$300 for 3-5 days, while 5G plans cost NT$500-999. All plans include unlimited data without throttling plus voice credits for local/international calls.
Taiwan Mobile allows online pre-ordering for airport pickup, but activation still requires passport verification at Taiwan Mobile counters. eSIM options require customer service contact via Facebook Messenger or Line app, making setup more complex than automated eSIM providers.
Taiwan Mobile offers limited international roaming to only 7 countries: Japan, South Korea, China, Hong Kong, Singapore, Thailand, and the US. Tourist airport SIMs cannot access roaming services - only standard prepaid plans with in-store activation support international use.
Chunghwa Telecom provides the widest coverage including remote areas, while Taiwan Mobile offers the second-best coverage with competitive speeds in urban areas. FarEasTone works well in cities but has limited rural coverage. For optimal coverage without carrier limitations, Truely eSIM provides access to multiple Taiwan networks automatically.
No, Taiwan Mobile tourist packages are one-time use only and cannot be extended or topped up. If you need longer service, you must purchase a new tourist package. This differs from standard prepaid plans which allow recharging but require more complex registration processes.
Taiwan Mobile supports eSIM since 2020 but requires customer service contact via Facebook Messenger or Line app for activation. The process takes 15 minutes typically and requires passport details. This is more complex than automated eSIM providers offering instant QR code activation.
Taiwan Mobile works well for Taiwan-only travel but lacks global coverage and modern convenience features. International eSIM providers like Truely offer global compatibility, instant activation, and often better value. Taiwan Mobile costs NT$300-1,600 ($9.90-52.90) while Truely provides global coverage at $2.50-5.52/day.
Taiwan Mobile serves as a competent traditional carrier for Taiwan-specific travel but shows clear limitations when compared to modern international connectivity solutions. While the company offers comprehensive tourist packages and reliable domestic coverage, fundamental restrictions limit its appeal for contemporary global travelers.
Taiwan Mobile works well for travelers staying exclusively in Taiwan who don't mind airport setup processes. The carrier provides extensive Taiwan coverage, unlimited data tourist packages, established infrastructure with English-speaking airport staff, and unique prepaid international roaming among Taiwanese carriers (though limited to seven countries).
However, significant limitations affect modern travel needs. Taiwan-only coverage requires new solutions for multi-country travel. Limited international roaming covers only seven countries with complex activation. Traditional setup requires airport visits with potential queue delays. Tourist packages cannot be extended or reused for future visits. Physical SIM management creates handling and loss risks.
Modern alternatives provide superior value through multiple advantages. Truely's Switchless™ eSIM technology eliminates setup complexity through one-click global activation. Multi-network access provides superior Taiwan coverage through automatic carrier switching. Global compatibility covers Taiwan and 189+ countries with seamless border crossing. True unlimited data policies include 10GB daily fair use then continued unlimited service. Professional support delivers 24/7 assistance in multiple languages.
Modern eSIM solutions save international visitors $20-150 per trip while providing superior coverage, unlimited data confidence, and global compatibility. The one-minute setup process eliminates airport queues, language barriers, and physical SIM management throughout Taiwan and beyond.
For international visitors seeking reliable, affordable, and convenient Taiwan connectivity with global flexibility, Truely's eSIM technology represents the future of travel communication. Skip traditional carrier limitations, avoid physical SIM complexity, and experience effortless Taiwan connectivity that continues working worldwide.
