eSIM for the Philippines and Japan: One Plan or Two?

Updated 22 October 2026 · Advinne editorial team · 5 min read

One regional eSIM can cover both countries if its plan lists the Philippines and Japan; otherwise use two country eSIMs. Here is how to choose and which local carriers offer eSIM.

Yes, one eSIM can cover both if you buy a regional plan whose country list names the Philippines and Japan. Otherwise, install two country eSIMs and switch between them. Your phone must support eSIM and not be carrier-locked. Globe and Smart in the Philippines, and povo in Japan, offer prepaid eSIM plans for travellers.

Can one eSIM cover both the Philippines and Japan?

Yes, if it is a regional plan that lists both countries. Apple notes that worldwide service providers sell plans with "different data amounts, duration, and countries or regions", so check that both countries are on the plan's list before you buy. Compare current plans and prices on each provider's own page. Last checked 22 October 2026.

One regional eSIM or two country eSIMs?

• One regional plan: a single install and one bill for the whole trip.
• Two country plans: you can pick a local carrier in each country.

On supported iPhone models, two eSIMs can be active at the same time, for example your home number plus a travel eSIM. Other phones vary, so check your phone maker's own page.

Which carriers in the Philippines and Japan support eSIM?

Apple's carrier list (published 15 September 2026) names:

• Philippines: Globe and Smart, both with prepaid eSIM plans for international travellers.
• Japan: au, NTT DOCOMO, Rakuten, SoftBank, UQ and Y!mobile for eSIM, and povo for traveller prepaid eSIM.

Does my phone support eSIM?

Check your phone maker's own list, because eSIM support varies by model and region. On an iPhone, "No SIM Restrictions" next to Carrier Lock means it is unlocked and can use another carrier's eSIM. You can also roam with your home carrier: ask about travel passes that include both countries.

What you need before you buy an eSIM

Phone Compatibility

Before buying an eSIM for your trip to Philippines and Japan, ensure your phone is compatible with the technology. Check if your device supports eSIM, as some older models may not be compatible.

Carrier Lock

Also, check if your phone is carrier-locked or unlocked. If it's locked to a specific network, you might need to unlock it before using an eSIM from another provider. This can be done through your carrier or by purchasing an unlocked device.

• Check your phone's specifications and compatibility with eSIM technology
• Verify the status of your phone's carrier lock (locked or unlocked)
• Consider purchasing an unlocked phone if yours is locked

How to set up your eSIM step by step

1. Ensure you have the necessary information:
2. Your eSIM provider's details (username and password)
3. The unique identification number (UNI) or activation code provided with your eSIM purchase
4. Check compatibility: Make sure your device is compatible with the eSIM technology. For example, if you're using an iPhone, ensure it supports eSIM.
5. Enable eSIM on your device:
6. On iOS devices, go to Settings > Cellular/Mobile Data and toggle "Use SIM Card" to enable eSIM
7. On Android devices, navigate to Settings > Connections > Mobile networks and select the eSIM option

Verify eSIM activation

1. Launch the eSIM provider's app on your device:
2. Follow the in-app instructions to activate your eSIM
3. Enter the UNI or activation code provided with your purchase
4. Wait for the activation process to complete

Final checks

• Confirm that your eSIM is activated by checking your phone's settings or the eSIM provider's app
• Make sure you have a stable internet connection before making calls, sending texts, or accessing data
• Stay connected with an eSIM in Taiwan and Japan

Tips to save data and avoid roaming charges

When traveling abroad with an eSIM in Philippines or Japan, it's essential to be mindful of your data usage to avoid excessive roaming charges.

Monitor Your Data Usage

Regularly check your phone's data usage to ensure you're not exceeding your daily limit. You can do this by going to your phone's settings and looking for the "Data Usage" or "Mobile Data" section.

• Disable background app refresh: Many apps continue to update in the background, consuming data even when you're not actively using them.
• Turn off auto-update: Prevent unnecessary app updates from downloading while abroad.
• Use Wi-Fi whenever possible: Connect to public hotspots or hotel networks to reduce your mobile data usage.

By being proactive and monitoring your data usage, you can avoid surprise bills and ensure a stress-free trip.

Common eSIM problems and quick fixes

Data usage concerns

When using an eSIM abroad, you may experience slower data speeds or limited coverage due to varying network conditions. To minimize issues:

• Check your eSIM provider's recommended settings for optimal performance.
• Consider purchasing a local SIM card or portable Wi-Fi hotspot for additional data access.

Carrier lock and compatibility issues

If your phone is carrier-locked, it may not work with the eSIM you purchased. Before traveling, ensure your device is compatible with the eSIM provider's network by checking their coverage and compatibility information.
