剛下飛機想馬上上網,卻被「實體卡、eSIM、機場櫃檯、超商、線上先買」搞得一頭霧水?這篇用「你是哪種旅客」的角度,把台灣上網方案一次講清楚。

剛下飛機、想馬上開 Google Maps 找飯店,卻發現手機沒網路——這大概是很多人第一次來台灣最緊張的一刻。好消息是台灣網路又快又便宜,機場一落地就能解決;真正麻煩的是選擇太多。先把最根本的差別講清楚:實體 SIM 卡是一張要插進手機卡槽的小卡;eSIM 是「虛擬 SIM」,掃個 QR Code 就能把方案裝進手機、不用換卡。兩者在台灣都能用到 5G/4G,速度差異不大,真正的差別在於「怎麼買、要不要換卡、有沒有台灣本地電話號碼」。要注意的是,eSIM 只適用較新的機型,例如 iPhone XS 以後(美版 iPhone 14 起甚至沒有實體卡槽)、較新的 Pixel 與部分三星旗艦;如果你的手機較舊、或想保留原本的門號同時上網,實體 SIM 或雙卡會比較實際。買 eSIM 前,務必先確認手機規格與是否已解除電信鎖。

三種上網方式,到底怎麼挑

台灣的上網方案大致分成三種:國際旅遊 eSIM、機場電信商實體 SIM,以及超商實體 SIM。下面這張表把各自的適合對象、優點與要注意的地方整理在一起;價格與方案內容易隨檔期變動,實際請以各家官方頁面與現場公告為準。

Method Who it suits Advantages Watch out for
Travel eSIM (e.g. Holafly) You just want data, hate hassle, and your phone supports eSIM Buy online before you leave, ready to use the moment you land, no queues, no registration Usually no local Taiwan phone number, can't make local calls
Carrier physical SIM (airport counter) You want a Taiwan number, want to make calls, or your phone doesn't support eSIM Unlimited data, includes call allowance, can be linked to local services like YouBike Requires queuing, passport registration, and cash in New Taiwan Dollars only
Convenience-store physical SIM (e.g. 7-Eleven ibon) You want to save a little, or only remembered to buy one after leaving the airport Many store locations, high flexibility Requires self-service registration (passport + a second ID + selfie); the process is a bit fiddly

如果落地就想無縫上網、又不想在機場排隊,旅遊 eSIM 通常是最省事的做法。你可以在出發前於線上買好、把 QR Code 掃進手機,落地後打開「數據漫遊」就自動連上網,完全不用排隊、不用換卡、不用臨櫃實名登記。以 Holafly 為例,台灣 eSIM 提供 3、5、7、10、15、30 天等吃到飽方案,支援 4G/5G,並可設定資料分享給同行親友。缺點是這類旅遊 eSIM 通常只提供上網、沒有台灣本地門號,需要打電話時可改用 WhatsApp、Line 等網路通話。

偏好實體卡、想要台灣本地門號的人,機場櫃檯仍是最直覺的做法。台灣三大電信是中華電信、台灣大哥大、遠傳電信,三家都在桃園機場(TPE)入境大廳設有櫃檯,領完行李出關就看得到。它們主打的「旅客上網卡(Tourist Prepaid)」幾乎都是吃到飽,並附一點通話額度。以覆蓋率最廣的中華電信為例,官方旅客預付卡提供多種天數的吃到飽方案,常見從 3 天、5 天、7 天到 10、15、30 天等;坊間資料的參考價約 3 天 NT$500、5 天 NT$600、7 天 NT$800、10 天 NT$1000、30 天 NT$1600 上下,實際天數、價格與是否含 5G 請以中華電信官網與機場櫃檯現場公告為準,且這類旅客卡通常無法續約或加值。辦理時,機場買卡通常只要護照一份即可(採實名登記);離開機場後在市區門市或超商辦,多半還需要第二證件(如簽證、入境許可、駕照或居留證)。付款方面,機場電信櫃檯多半只收新台幣現金,建議先在入境大廳的外幣兌換櫃檯或 ATM 準備一點現金。這也帶出很多人卡關的「實名登記」:台灣法規要求電信門號採實名制,向本地電信商買卡時需出示護照等證件;而國際旅遊 eSIM(如 Holafly、Airalo)走的是國際漫遊網路,通常免自行實名登記、下載即用——這正是它最大的便利之處。

那到底該選哪一種,其實看你是哪種旅客。短天數、只要上網的觀光客,手機支援 eSIM 就直接買旅遊 eSIM 吃到飽、落地即用最省心,不支援就到機場中華電信/台灣大哥大櫃檯辦 3~7 天吃到飽。需要台灣門號的人——長住、找工作、要收簡訊驗證——建議辦本地電信商實體 SIM,有本地號碼才方便綁定台灣的 App、銀行或 YouBike,這部分可參考我們的Taiwan Living Guide。要跑山區、東部的深度旅客,本地電信(尤其中華電信)在偏遠地區覆蓋通常較穩,前往Alishan、花蓮等地時值得考慮;想同時安排交通與門票,也可看看Transport Guide。更多台灣網路與 eSIM 的實用資訊,則可瀏覽eSIM & Internetcategory.

Frequently Asked Questions

Is it better to buy internet access in Taiwan at the airport or online?

It depends on what you want. For "zero waiting, no lines," buy a travel eSIM before you leave; for "a local Taiwan phone number that can make calls," get a physical SIM at an airport telecom counter. The two offer little difference in speed in urban areas.

Do I definitely need my passport to buy a SIM card?

Yes. Taiwan phone numbers use real-name registration, so buying a local SIM requires presenting your passport to register; at the airport a passport is usually all you need, while buying downtown or at a convenience store may require a second form of ID. Travel eSIMs, on the other hand, usually require no separate real-name registration.

Does an eSIM require swapping cards? Can I keep my original phone number?

eSIM 不用換實體卡,掃 QR Code 即可安裝。多數支援雙卡的手機可以同時保留原門號(用來接電話/簡訊)+用 eSIM 上網,但請先確認手機支援 eSIM 且已解鎖。

Is unlimited data really unlimited? Will the speed be throttled?

Most mainstream traveler plans in Taiwan are "unlimited data," but whether there's actually a fair-use policy or hotspot-sharing limit varies slightly by provider, so please refer to the official plan description.

Can I set up my internet access before I get off the plane?

Yes. You can scan and install a travel eSIM's QR code onto your phone before you leave, and once you land, turning on data roaming connects you automatically; a local physical SIM, on the other hand, must be arranged in person after you land.
