每個方案在你落地的那一刻就能用。沒用完的流量會在線路關閉時回到錢包，而且就算餘額歸零，顧客每月仍有至少 100 MB 免費救援流量。

在香港，92 Mbps 實際代表什麼

在香港使用 Orbislo 的一般下載速度：92 Mbps。這明顯高於亞洲的中位數 43.9 Mbps。

第十百分位是 29 Mbps。中位數和下限之間有這樣的落差很常見，煩躁也就從這裡來：多數時候很快，在最擁擠的那幾個百分比的時刻明顯變慢，通常發生在尖峰時段的車站和機場。

這個速度下，手機上做的任何事都不會被連線拖住。視訊通話很順，筆電開熱點可以撐一整個工作天，大批照片備份也不必特地安排時間。

你會連上哪些電信網路

在香港，Orbislo 透過 CSL 和 SmarTone 傳送你的流量。你的手機不會被綁在其中一家。當你所在的網路壅塞或斷線時，設定檔會把你換到另一家，過程沒有任何提示，你唯一會察覺到的就是連線一直沒斷。

這件事比檯面上的速度更重要。現在市面上的旅行 eSIM 幾乎都只是把每個國家的單一上游合約轉賣出去，所以那個網路狀況不好的那一小時，你就跟著不好，唯一的辦法是再向別家買第二張 eSIM。背後有多個網路的設定檔，可以替你做一個你永遠不會看到的決定。

香港的 5G：有，非獨立組網。值得知道的是，旅行設定檔能用 5G 是常態而非特例，真正決定旅程體感的是上面那個第十百分位，不是狀態列上的世代標示。

只接一家電信商的業者，做不到這個切換。

在香港的上網費用

香港的 100 MB 方案從 $0.30 起，換算下來每 GB 是 $0.00。比較不同業者時該看的就是這個數字，因為掛在不同流量上的標價其實什麼都說明不了。

多數業者不太希望你做的比較，是實際用掉的每 GB 成本。針對旅行數據的獨立調查指出，購買的流量中有 20% 到 35% 因為過期而消失，因為第三十天到期的方案會直接刪掉你沒用完的部分。Orbislo 的流量沒有到期日，你付過錢的那一 GB，下一趟旅行還在。同樣的標價，等於多出 25% 到 40% 真正能用的流量；在香港，這代表實際成本比較接近每 GB $0.00，而不是 $0.00。

因為不會過期，買香港的流量最省的方式，是買得比你以為需要的少一點，不夠再加值。加值大約十秒就好，也不用安裝任何東西。買太多在別的地方是昂貴的錯誤，在這裡只是沒差。

抵達香港之後

出發前先在家裡的 WLAN 上安裝。設定檔會在你還有可信任的連線時下載完成，接著就靜靜待著，直到你降落在香港並連上 CSL。

落地後只有一件事要檢查：Orbislo 這條門號的數據漫遊必須打開。iOS 和 Android 預設都是關閉的，而這裡的漫遊跟資費無關，因為方案是預付的，根本沒有帳單會被灌爆。把 Orbislo 那條打開、原本那條關著，你原本的號碼就能繼續接電話和銀行驗證碼，而且不會產生費用。

在香港辦當地 SIM 卡

Hong Kong runs a real name registration programme under the Telecommunications (Registration of SIM Cards) Regulation, and every prepaid card supplied by a Hong Kong operator has to be registered before it will activate. A visitor without a Hong Kong identity card registers on another valid identity document.

在香港受限的服務

Roaming eSIMs outside the registration rule: Hong Kong's real name rules cover every SIM and eSIM that a Hong Kong licensee supplies for use here, but not a SIM or eSIM from a provider licensed elsewhere that a visitor uses on inbound roaming. Such a roaming eSIM needs no Hong Kong registration.
Local travel SIMs: A travel SIM from a Hong Kong operator that also works inside Hong Kong has to be registered before it is activated for use here. Only cards that work solely abroad, over outbound roaming, fall outside the rule.
Documents refused for registration: Anyone who holds a Hong Kong identity card must register a local SIM with that card. Others use a valid passport or travel document, but a Hong Kong SAR passport or a British National (Overseas) passport is not accepted as proof of identity.
Pre-registered cards: Buying a prepaid card sold as already registered, or registering with false details, can amount to a criminal offence such as obtaining services by deception under the Theft Ordinance. Operators also run sample checks, and a card is deregistered if an irregularity turns up and its user does not help confirm the details.
Mainland signal near the boundary: Near the Shenzhen boundary and on some outlying islands, a phone can switch to a Mainland China network. Calls and data are then charged as roaming, so setting the phone to select a Hong Kong network manually keeps usage on the local plan.
Emergency calls on a Mainland network: Dialling 112 or 999 on any local network with coverage reaches the 999 centre. A phone attached to a Mainland network cannot reach it through 00852 112 or 00852 999, so the advice there is to dial 00852 and a Hong Kong police station or a contact.
Older VoLTE handsets: With 2G and 3G closing, some early 4G handsets that support only an older version of VoLTE may be unable to call 999 or 112 over VoLTE. The regulator tells owners of such phones to ask whether they need a software update or a replacement.

關於香港值得知道的事

沒有香港身分證而登記的人，還必須聲明自己並未持有香港身分證，而且沒有用另一份證件登記過，這就排除了把一個身分攤到好幾張卡上的做法。
在香港，一個人在每家業者最多登記 10 張預付卡，公司最多 25 張，所以一群人用同一個身分買卡會碰到上限。
Hong Kong's Emergency Alert System reaches visitors too. A phone roaming onto a local network receives the government's cell broadcast alerts, free of charge, as long as its cell broadcast feature is switched on, and each alert sounds an alarm with vibration for about ten seconds.
Alerts at the Extreme Emergency Alert level cannot be switched off or muted, while the lower Emergency Alert level can be turned off. The system needs a 3G, 4G or 5G connection, and it does not reach phones outside Hong Kong's local networks.
Texting 992 reaches the police only from a number registered in advance under the scheme for people who cannot use 999 because of a speech or hearing impairment. Registration goes through the police online platform or a police station.
Since 31 December 2024, anyone answering a call from a newly activated Hong Kong prepaid SIM first hears a recorded warning that the call comes from a new prepaid card. People you ring from a freshly bought local card hear it before the call connects.
On a Hong Kong mobile line, an incoming call that shows a +852 number but originates outside Hong Kong triggers a free voice or text warning: "Call is from outside Hong Kong. Beware of deception." All mobile providers have sent it since 1 May 2023.
Under the SMS Sender Registration Scheme, registered organisations text local mobile subscribers from sender IDs that begin with #, and the networks block other messages whose sender IDs use # without registration. A # prefix is therefore a mark of a genuine sender.
Hong Kong levies no value added tax or sales tax of any kind, so nothing of that kind is added to the price of a mobile plan, top up or handset bought here.
