🌍 Top 10 iPhone Issues in Taiwan — And How to Fix Them
來台旅遊 iPhone 常見 10 大問題與解法
Stay connected and stress-free during your trip
讓你的旅程順暢不中斷
For many travelers, an iPhone isn’t just a phone — it’s your map, translator, payment method, and everyday travel companion.
對許多旅客來說，iPhone 不只是手機，更是導航、翻譯、付款與旅途中的得力助手。
However, once you arrive in Taiwan, things don’t always work as expected. Most issues aren’t caused by hardware problems, but by settings — such as eSIM activation, Apple ID region, dual SIM configuration, transportation payments, or charging.
但實際來到台灣後，手機不一定能正常運作。多數問題並非硬體故障，而是來自設定，例如 eSIM、Apple ID 地區、雙卡設定、交通支付或充電等。
