OnePlus phones with eSIM: which models and how to set up
Key facts
- Dialing *#06# is the only reliable way to confirm eSIM on a OnePlus: an EID number means yes, IMEI only means no.
- OnePlus eSIM support depends on the regional variant, so model name alone never proves compatibility.
- Install the VoaSim QR at home but keep the line off — days start at the first connection abroad.
- VoaSim data is truly unlimited, with no cap or throttling, from USD 18.90 for 5 days down to USD 1.78/day on the 60-day plan.
- If the eSIM shows no signal, run the roaming and manual-network checks, then use the free eSIM Rescue tool at voasim.com/sos.
Check if your phone has eSIM
OnePlus eSIM support is confusing because the same model can ship with eSIM in one country and without it in another. Instead of hunting for spec sheets, do the 10-second check on your own phone and you will know for sure.
This guide shows the check, the exact setup steps on OxygenOS, the mistakes that burn days of validity, and what to do if the eSIM shows no signal after you land.
How to know if your OnePlus has eSIM (10 seconds)
There is one universal test that works on any phone, any brand, any region:
- Open the phone dialer.
- Type *#06#. No call button needed.
- Read the screen. If an EID appears (a long number, usually 32 digits) next to the IMEI, your OnePlus has eSIM hardware enabled.
Second check: go to Settings > Mobile network (or SIM card & mobile data) and look for an option like Add eSIM or Add data plan. If it is there, you are set.
Two extra conditions apply no matter which OnePlus you own. The phone must be carrier-unlocked — a device locked to a US or European operator will refuse a third-party profile. And the system should be on a current OxygenOS build, since eSIM menus have moved between versions. If no EID shows up, your variant does not support eSIM and no app or update can add it. VoaSim does not sell physical SIM cards, so in that case you would need a local SIM at the destination.
Which OnePlus models usually support eSIM
OnePlus rolled eSIM out later than Apple and Samsung, and support is tied to the regional variant more than to the model name. Recent flagships and foldables sold in markets where operators pushed eSIM generally include it; several Nord and India-market units do not, even on the same generation.
Practical rule: treat any OnePlus released from 2020 on as a likely candidate, then confirm with *#06#. Never buy a travel eSIM based on a model name alone.
| Situation | What it means |
|---|---|
| *#06# shows IMEI + EID | eSIM ready — you can install VoaSim |
| *#06# shows IMEI only | No eSIM hardware on this variant |
| EID shows but menu is missing | Update OxygenOS, then look again under Mobile network |
| Phone locked to a carrier | Ask your operator to unlock before travel |
If you also travel with an iPhone or a Samsung, the same VoaSim QR logic applies — see the full setup guides.
Installing a VoaSim eSIM on OxygenOS, step by step
Do this at home, on Wi-Fi, before you fly. The QR code arrives by email within minutes of purchase.
- Open Settings > Mobile network (or SIM card & mobile data).
- Tap Add eSIM / Add data plan and choose to scan a QR code.
- Point the camera at the QR from your email. Confirm the download.
- Name the line something obvious, like "VoaSim trip".
- Leave the eSIM line switched off. On Android this matters: do not enable its data before you travel.
When you land, turn the VoaSim line on, set it as the line for mobile data, and enable data roaming for that line only. Your physical SIM stays in the phone and your number keeps working — WhatsApp still runs on your number. Just turn off your home carrier's data roaming so it cannot bill you in the background.

Validity: when your days start counting
VoaSim days start at the eSIM's first connection to a network at the destination, not at purchase and not at install. That is why the install-early-activate-late routine works so well on OnePlus: you scan the QR at home with a calm Wi-Fi connection, keep the line off, and lose nothing.
The risk on Android is switching the new line on "just to test" while still at home. If it latches onto a network, the clock can start. Test the install, not the connection — seeing the profile listed in Settings is proof enough.
Other rules worth knowing: trips of 1 to 4 days pay the 5-day package, and the maximum is 90 days per eSIM. Long stay? The 60-day plan brings the daily cost down to USD 1.78, the lowest rate on the table. Add a second eSIM in the same order and it gets 10% extra off — handy when two OnePlus phones travel together.
Prices and what "unlimited" means here
One price per duration, the same for all 170 destinations covered, including the Europe plan that works across 50 countries with a single eSIM — Switzerland, the UK, Turkey, Norway and Iceland included. Today's prices already include the 15% promo:
| Duration | Price | Per day |
|---|---|---|
| 5 days | USD 18.90 | USD 3.78 |
| 7 days | USD 23.90 | USD 3.41 |
| 10 days | USD 30.90 | USD 3.09 |
| 15 days | USD 42.90 | USD 2.86 |
| 30 days | USD 61.90 | USD 2.06 |
| 60 days | USD 106.90 | USD 1.78 |
Truly unlimited means no data cap, no speed throttling and no hidden fair-use clause. It is a data-only line: no phone number and no traditional voice calls, but WhatsApp, app calls, maps and streaming run over data. Payment is by international credit or debit card in USD through Stripe, invoice by email.
OnePlus eSIM with no signal? Run these checks in order
Ninety percent of "eSIM not working" cases on Android are settings, not the profile. Work through this list before contacting anyone:
- Airplane mode on for 10 seconds, then off.
- Settings > Mobile network: the VoaSim line is enabled and selected for mobile data.
- Data roaming ON for the VoaSim line — this is the single most common miss.
- Your home SIM: data roaming off, so it does not fight for the data slot.
- Network selection: switch to manual and pick another local operator from the list.
- Preferred network type: allow 4G/LTE rather than forcing 5G only.
- Restart the phone once.
Still dark? Use the free eSIM Rescue tool — it diagnoses an eSIM of any brand, not only VoaSim. Human support answers by chat or at hola@voasim.com. If the eSIM will not connect and support cannot fix it, you get a 100% refund.
OnePlus travel eSIM vs other options
No option wins for everyone. Pick by trip shape.
- Sold by GB (Airalo, Nomad, Ubigi, Saily, GigSky and similar): often cheaper for a light week — email, maps, a few messages. Check the cap, validity window and tethering rules in each brand's own terms.
- Carrier roaming (T-Mobile, AT&T, Verizon, EE, Vodafone, Rogers, Telstra, Google Fi and others): the simplest path, since your number keeps texting and calling normally. Daily or bundled pricing, usually with a daily allowance and reduced speed afterwards, and it often has to be enabled before you leave. Check the current rate in your carrier app.
- Local physical SIM: usually the cheapest per GB on long stays, but it costs shop time, passport registration in many countries, and your home number leaves the phone.
- VoaSim: best when you want to stop counting GB — hotspot-heavy or streaming trips aside, since tethering depends on the plan and should be confirmed with support first.
