OnePlus 15 & eSIM — Yes on Global Models, Here's How to Use It

آخر تحديث: 2026-10-15

Does the OnePlus 15 support eSIM?

Yes — the OnePlus 15 supports eSIM on its global and international variants (European, North American, and other worldwide models). It's a dual-SIM phone: you can pair one physical nano-SIM with an eSIM and run two lines at once, which is exactly what you want for travel.

The one honest caveat: models sold in China typically ship without eSIM, using two physical nano-SIM slots instead. This is a common pattern for phones released in the Chinese market. So if you bought your OnePlus 15 through a global/international channel, you have eSIM; if you imported a China-market unit, you may not.

To confirm eSIM on your OnePlus 15, either:

• Go to Settings → Wi-Fi & network → SIM & network → Add eSIM, or
• Dial *#06# — if an EID number appears next to the IMEI, your OnePlus 15 has eSIM

If either shows up, you're ready to add a travel plan.

What this means for travelers

With eSIM on your OnePlus 15, getting online abroad is a two-minute job instead of an airport errand:

• Buy a data plan for your destination and receive a QR code by email
• Scan it once — the eSIM installs over Wi-Fi in seconds
• Land and connect — the plan activates on a local partner network automatically
• Keep your home SIM in the tray for your regular number

No SIM-card shops, no swapping the tiny tray, and typically a lot cheaper than your home carrier's roaming rates.

How to set up a travel eSIM on the OnePlus 15

OxygenOS puts eSIM under the SIM & network settings. Do this at home on Wi-Fi before you fly:

1. Buy an eSIM plan for your destination — your QR code arrives by email (and is saved on your profile page)
2. Open Settings → Wi-Fi & network → SIM & network
3. Tap Add eSIM (or + next to the SIM section, then Download a SIM)
4. Scan the QR code from your email
5. Wait a few seconds while OxygenOS downloads the profile — stay on Wi-Fi
6. Name the eSIM (e.g., "Travel data") so it's easy to spot later

When you arrive, open your travel eSIM under SIM & network and:

• Set it as the line for mobile data
• Turn Data roaming ON for the travel eSIM (travel plans use local partner networks, which counts as roaming)
• Turn Data roaming OFF on your home SIM to avoid extra charges
• Keep calls and texts on your home SIM

No data after landing? Add the APN from your profile page under the eSIM's Access Point Names — some models need it entered by hand. Our Android eSIM setup guide shows every screen.

How many eSIMs can the OnePlus 15 store?

The OnePlus 15 can store up to 8 eSIM profiles on the device. On most global units, one physical nano-SIM and one eSIM are active together (dual-SIM), so the standard travel setup is your home SIM plus one active travel eSIM.

A note on dual-eSIM: the India variant supports two eSIM profiles, but only one eSIM is active for voice/data at a time (the other stays in standby). On global units, dual-eSIM operation is being rolled out via software update — but for travel, the reliable combination is simply your physical SIM plus one travel eSIM.

Either way, you can:

• Keep your home carrier on the nano-SIM
• Activate a travel eSIM for your current trip
• Store eSIMs for countries you visit often and re-activate them later

Do I need a special eSIM for the OnePlus 15?

No. Any standard travel eSIM works on the OnePlus 15 — there's no OnePlus-specific eSIM. It uses the same GSMA standard as every eSIM phone. Just make sure your provider covers your destination country.

What about calls and texts?

An eSIM-Now travel plan is data-only: fast mobile internet, but no phone number, so it can't make regular calls or receive SMS/OTP codes on its own. On a dual-SIM OnePlus 15 that's easy to work around:

• Keep your home SIM active for calls and texts
• Use WhatsApp, Google Meet, Signal or Telegram to call and message over data
• Turn on Wi-Fi calling with your home carrier if you want to receive regular calls abroad
