eSIM （電子 SIM 卡） 是一種內建於手機內的嵌入式 SIM 卡，取代了傳統的實體 SIM 卡。用戶無需插卡，只需透過 SmarTone 提供的 QR Code 即可下載及啟用。

請參閱 SmarTone 官方網站以了解支援 eSIM 的手機或裝置型號。若確認支援 eSIM，進行轉換時候，請使用 Wi-Fi 連接，避免 SIM 卡轉換時未能接受訊息。

所有 SmarTone 月費計劃均支援 eSIM，儲值卡目前則尚未支援 eSIM。進行轉換時候，請使用 Wi-Fi 連接，避免 SIM 卡轉換時未能接受訊息。

選擇實體 SIM 卡或 eSIM 主要取決於你的手機或裝置型號、使用習慣及個人需求。
建議使用實體 SIM 卡的情況：
1. 你的手機或裝置不支援 eSIM
2. 你經常更換手機，使用實體 SIM 卡更方便轉移至其他裝置

如你使用 SmarTone 月費計劃的實體 SIM 卡，可透過 SmarTone 官方網站或 SmarTone CARE App，自行轉換為 eSIM。你亦可親臨任何一間 SmarTone 門市，由專員親自辦理。
進行轉換時候，請使用 Wi-Fi 連接，避免 SIM 卡轉換時未能接受訊息。

如你已成功取得 eSIM 二維碼並收到由 SmarTone 發出的啟用 eSIM 電郵，請按所述指示掃描二維碼以完成啟用程序。

每個 eSIM 二維碼只限一部手機或裝置使用。如你在第二部裝置上掃描相同 eSIM 二維碼，將無法成功啟用。若需更換手機或裝置，請按指示進行更換。
進行轉換時候，請使用 Wi-Fi 連接，避免 SIM 卡轉換時未能接受訊息。

eSIM 與實體 SIM 卡在功能上基本一致，均可設定為主號碼或副號碼，視乎你所使用的手機或裝置內的設定，使用上亦無大分別。

如你的 SmarTone 月費計劃已啟用「一卡兩號」服務，當你將實體 SIM 卡轉換為 eSIM 時，兩個電話號碼亦必需同步轉換，並可繼續使用相關服務而不受影響。請參閱 SmarTone 官方網站，以了解支援 eSIM 的手機或裝置型號。

如你的新手機支援 eSIM 並已選用 SmarTone 月費計劃，你可考慮將 SmarTone 實體 SIM 卡轉換為 eSIM，並保留中國內地 SIM 卡作為實體 SIM 卡使用，減少頻繁轉換實體 SIM 卡的不便。
提提你！根據目前資料，內地 eSIM 服務只適用於內地 eSIM 手機。若你的手機是在其他地區購買，即使支援 eSIM，亦可能無法使用內地 eSIM。
如你計劃在內地使用 SIM 卡，建議選用支援實體 SIM 卡的手機，以確保通訊服務穩定。如對支援內地 eSIM 的詳情有進一步疑問，建議直接向相關內地電訊商查詢。

根據目前資料，你必須使用在中國內地購買及支援 eSIM 的 iPhone 型號（如A3518），並需親身前往內地電訊商的門市辦理。其他地區購買的 iPhone 即使支援 eSIM，亦無法使用內地的 eSIM 服務。
若你已有內地的實體 SIM 卡，建議考慮使用支援實體 SIM 卡的手機（如 iPhone 17 Pro Max），以確保服務正常運作。
如有進一步疑問，請向相關內地電訊商查詢。

經任何渠道（包括門市或網上申請）更換 SmarTone 的實體 SIM 卡或 eSIM 均需繳付 HK$50 手續費。
不過，SmarTone 每年將提供 3 次免費更換 SIM 卡的配額，讓你在需要更換 SIM 卡時更靈活方便，無需擔心額外費用。
每張 eSIM 只限一部手機或裝置使用。如你需要在第二部手機或裝置安裝 eSIM，便要換另一張 eSIM。

An eSIM (embedded SIM) is a digital SIM card that is built directly into your phone, eliminating the need for a physical SIM card. This technology allows users to download and activate the service simply by scanning the QR code provided by SmarTone without inserting a physical SIM.

Please visit the SmarTone official website to check the eSIM-compatible devices. If eSIM support is confirmed, please connect to Wi-Fi during the eSIM transfer to ensure you receive messages when changing the SIM card.

All SmarTone monthly service plans support eSIM, while prepaid SIM cards are not yet supported.
During eSIM transfer, please connect to WIFI to avoid not receiving messages when changing the SIM card.

The choice between a physical SIM card and eSIM depends on your phone or device model, usage habits, and personal needs.
A physical SIM card is recommended in these cases:
1. Your phone or device does not support eSIM.
2.You frequently switch devices, as a physical SIM card is easier to transfer.

If you use a physical SIM card with a SmarTone monthly plan, you can convert to an eSIM through the SmarTone official website or SmarTone CARE App using the self-service option. Alternatively, you can visit any SmarTone store, where a specialist can assist you in person.
During eSIM transfer, please connect to WIFI to avoid not receiving messages, as switching SIMs may interrupt messaging.

If you have successfully obtained the eSIM QR code and received an activation email from SmarTone, follow the instructions to scan the QR code and complete the activation process.

Each eSIM QR code is limited to one phone or device. Scanning the same eSIM QR code on another device will not work. To switch to a new phone or device, please follow the provided replacement instructions.
During eSIM transfer process, please connect to WIFI to avoid not receiving messages, as switching SIMs may interrupt messaging.

eSIM and physical SIM cards are functionally similar, both capable of being set as the primary or secondary number depending on your phone or device settings.

If your SmarTone monthly service plan has activated the "1 Card 2 Numbers" service, when you convert your physical SIM card to an eSIM, both phone numbers will be converted simultaneously and you can continue using the related services without any interruption. Please visit the SmarTone official website to check for eSIM-compatible phone or device models.

If your new phone supports eSIM and you are using a SmarTone monthly service plan, you may consider converting your SmarTone physical SIM card to eSIM. You can keep the mainland China SIM card as the physical SIM to avoid the inconvenience of frequently swapping physical SIM cards.
Reminder! Based on current information, mainland China eSIM services are only compatible with eSIM-compatible devices purchased in mainland China. Even if your phone supports eSIM but was bought in other regions, it may not work with a mainland eSIM. If you plan to use a SIM card in mainland China, we recommend choosing a phone that supports a physical SIM card to ensure stable communication services. For further details on mainland eSIM support, please contact the relevant mainland telecommunications service provider directly.

Based on current information, you must use an iPhone model purchased and eSIM-enabled in mainland China (e.g. A3518) and visit a mainland telecommunications service provider's store in person to activate it. iPhones bought in other regions, even if eSIM-compatible, cannot use mainland China’s eSIM services.
If you already have a mainland physical SIM card, we recommend using a phone that supports a physical SIM (e.g. iPhone 17 Pro Max) to ensure service reliability. For further questions, please contact the relevant mainland telecommunications service provider.

Replacing a SmarTone physical SIM card or eSIM through any channel (including in-store or online) incurs a HK$50 handling fee. However, SmarTone provides a quota of 3 free SIM replacements per year, offering flexibility and convenience without additional costs.
Each eSIM is restricted to a single phone or device. To use an eSIM on another device, you will need to obtain a new eSIM.
