OPPO and eSIM
OPPO supports eSIM mainly on the Find series, and support depends clearly on the sales market. The Reno and A lines sold in Thailand still use physical SIMs.
| Model | eSIM | Year | Notes |
|---|---|---|---|
| Find X8 Pro | Yes | 2024 | Market dependent |
| Find X8 | Yes | 2024 | Market dependent |
| Find X7 Ultra | No | 2024 | Mainland China variants commonly ship without eSIM — check your own handset's settings menu. |
| Find X5 Pro | Yes | 2022 | European variants only |
| Find N3 | Yes | 2023 | Market dependent |
| Reno series | No | 2024 | Varies by model — eSIM on Reno13 and Reno13 Pro, not on most older ones |
| A series | No | 2024 | Normally ships without eSIM — confirm in your handset's SIM menu. |
How to check on the phone
- Open Settings → Connection & sharing → SIM card & mobile data
- Look for Add eSIM
- ColorOS versions name the menu differently — try searching Settings for eSIM as well
Things to know
- Mainland China units typically do not support it.
- The same model can carry a different SIM spec in Europe and in Southeast Asia — most Thai-market units have no eSIM.
What OPPO's own spec pages confirm
OPPO's Find X8 Pro spec pages for both OPPO Global and OPPO Thailand give the SIM type as Nano-SIM card/Nano-USIM card + eSIM, so the Thai-market Find X8 Pro carries eSIM according to the manufacturer. For other models in the table on this page, open OPPO Thailand's spec page for that exact model and read the SIM card type line under the cellular network section.
Where the eSIM menu sits on ColorOS
On ColorOS the SIM menu usually sits under the connections group, such as Settings → Mobile network or Connection & sharing → SIM card & mobile data. The group name changes between ColorOS versions, so the quickest route is to type eSIM in the search box at the top of Settings.
Check your own OPPO before you buy a plan
- Open the Phone app and dial *#06#. If the screen shows an EID (a 32-digit number), the handset has an eSIM chip. If you see only IMEI numbers, treat it as unconfirmed and carry on with the next check, because some phones do not show the EID on this screen.
- Open Settings → Mobile network, or search Settings for eSIM. If there is a button to add or download an eSIM, the software for your unit's market has the feature switched on.
- Find the model code under Settings → About phone and compare it with the manufacturer's spec page for the country you bought it in. The model code is more reliable than the marketing name, because one name can cover several market variants.
- If the phone is second-hand or imported, ask the seller whether it is network locked. A unit locked to an overseas carrier usually refuses another operator's profile even when an EID is present.
Installing an eSIM on a OPPO, step by step
- 1Install in Thailand before you flyConnect to stable Wi-Fi and install the eSIM while you are still at home. If the scan fails you still have time to contact the shop, which beats troubleshooting at the arrival airport with no data.
- 2Open the add-eSIM menuOn a OPPO, go to the eSIM menu found by searching Settings → Add eSIM and choose to scan the QR code. If the QR code is on the same phone and you cannot scan it, choose to enter the activation details by hand (the SM-DP+ address and activation code from your email).
- 3Label the lineRename the new line, for example Travel or the country name, so you do not mix it up with your Thai SIM when choosing the data line.
- 4Leave it off until you landIf the plan's validity starts on first network connection, keep the eSIM line switched off and turn it on only when you reach the destination.
- 5Turn on data roaming for the eSIM lineMost travel eSIMs run as roaming on a local network. If the line shows signal but no data, switch on Data roaming in that eSIM line's settings.
Switching the data line while travelling
On a dual-SIM OPPO, calls and texts can use a different line from mobile data. The setting to change is the mobile data line, found at the SIM card & mobile data page → Default data SIM or similar.
- Set mobile data to the travel eSIM and keep your Thai SIM for calls and texts, so bank OTP messages still arrive.
- Switch off Data roaming on the Thai SIM, so the phone cannot fall back to it and run up roaming charges.
- If the menu offers automatic data switching during calls (labelled Mobile data switching or similar), turn it off while abroad.
- Back in Thailand, move mobile data back to the Thai SIM, then turn off or delete the expired eSIM line.
Common problems on OPPO
| Problem | Usual cause | What to do |
|---|---|---|
| Searching for eSIM finds nothing | A Reno or A series model without eSIM | Check that model's Thai spec page; use a physical SIM if absent |
| Mainland China unit has no menu | Different spec from the global model | Use a physical travel SIM |
| Signal but no data | Roaming off or wrong data line | Turn on roaming and set it as the data line |
| Error after scanning | Weak connection or the QR code was already used | Reconnect to Wi-Fi, then contact the shop |
