如何打開iPhone漫遊

要開啟iPhone的數據漫遊，首先確認你的運營商套餐是否包含漫遊服務，若包含則可在設置中啟用。具體步驟為：1. 進入“設置”；2. 點擊“蜂窩網絡”或“移動數據”；3. 開啟“數據漫遊”。此外，建議在出國時先開啟飛行模式以避免意外費用，再根據需要手動開啟蜂窩數據和漫遊功能。同時注意，即使開啟數據漫遊，能否連接仍取決於運營商協議及所在地區，且語音漫遊可能通過Wi-Fi或特定應用實現。最後，務必核實套餐詳情，防止產生額外費用。

Turning on roaming on your iPhone is a straightforward process, but it's important to understand what you're doing before flipping the switch. Roaming allows your phone to connect to other networks when you're outside your carrier's coverage area — typically when traveling internationally or in remote areas. Here's how to enable it and what you need to know.

Check if Your Carrier Plan Includes Roaming

Before turning on data roaming, it's crucial to verify whether your current plan includes international or extended network usage. Some carriers offer roaming as part of their standard plans, while others require you to opt-in or pay extra for it.

• Contact your carrier or log into your account online to check roaming options.
• Be aware of any additional charges that may apply once you start using data abroad.
• Consider purchasing a travel-specific plan if available — these often offer better rates.

If roaming isn't included in your plan or hasn't been activated, turning it on in your settings won't make a difference.

Enable Data Roaming in Settings

Once you've confirmed that your plan supports roaming, you can turn it on directly from your iPhone settings:

1. Open Settings .
2. Tap Cellular (or Mobile Data , depending on region).
3. Scroll down and toggle on Data Roaming .

This will allow your iPhone to connect to partner networks when you're out of your home network's range.

Note: Even with data roaming enabled, your phone might not connect automatically unless it's set to find networks manually or your carrier has roaming agreements in place.

Also, keep in mind that voice roaming usually works differently — some carriers handle voice calls over Wi-Fi or through specific apps instead of traditional roaming.

Use Airplane Mode Smartly When Traveling

When arriving in another country, many people turn on Airplane Mode to avoid unexpected charges, especially if they're not connected to Wi-Fi right away. However, this doesn't mean you have to stay disconnected:

• With Airplane Mode enabled, go into Settings > Cellular and manually toggle back on Cellular Data and Data Roaming if needed.
• This ensures that only cellular functions are controlled individually, allowing Wi-Fi to still work normally.

Some newer iPhones also let you use an eSIM with a local carrier plan, which can be more cost-effective than relying on your original carrier's roaming services.

That's basically all there is to it. Just remember, enabling data roaming doesn't guarantee a connection — it depends on your carrier's partnerships and your location. And always double-check your plan to avoid surprise charges.
