Fixing iD Mobile Roaming Data on OPPO
Go to Settings → SIM card & mobile data → Data Roaming and enable the Data Roaming toggle. This must be switched on for iD Mobile mobile data to work outside the UK.
Check the iD Mobile app or your plan details. EU roaming included on most plans. Some plans require a roaming add-on — verify before travelling.
Go to your mobile network settings and set Network Type or Preferred network to Auto or LTE/3G/2G Auto. Forcing 5G Only can prevent roaming registration.
Go to Settings → Mobile Network → Network Operators → Search manually. Select a local network that has a roaming agreement with iD Mobile.
Roaming uses the same APN as domestic data. Verify Settings → SIM card & mobile data → [SIM] → Access Point Names shows APN: id. Some devices reset APN settings after crossing borders.
After landing, restart your OPPO to force re-registration on a local roaming partner network. Allow 5 minutes before testing data.
If data does not work after completing these steps, call iD Mobile on 7777 (from iD Mobile) from a Wi-Fi connection. The roaming feature may need to be manually enabled on your account.

Frequently Asked Questions
Does iD Mobile charge extra for EU roaming?
EU roaming included on most plans. Check your specific iD Mobile plan in the app — some older plans or certain MVNOs require a roaming add-on even for EU destinations.
Why does my OPPO show signal abroad but no data?
Signal bars confirm you are registered on a roaming network, not that data is active. Enable data roaming at Settings → SIM card & mobile data → Data Roaming and verify your iD Mobile plan includes data roaming for that country.
Which countries can I roam with iD Mobile?
EU roaming included on most plans. For destinations outside the standard roaming zone, check the iD Mobile website for individual country roaming status or contact 7777 (from iD Mobile) before travelling.
