Follow the Universal Link or Open Settings

Set eSIM as Your Data Source
- Make sure the eSIM is actually used for data: Settings → Cellular → Tap Cellular Data.

- This prevents the phone from falling back to your primary line and accidentally roaming it.

iPhone Data Optimization (Recommended)
- We recommend optimizing the use of cellular data while roaming — very effective, no downside.
- Open "Settings" on your iPhone or iPad.
- Tap on "Cellular" or "Mobile Data".
- Scroll down and toggle "Low Data Mode" on.
- Now switch off WiFi (for testing cellular data) and go to Airplane Mode for a few seconds.
- Then turn off Airplane Mode and wait a few seconds for the phone to register on network and "climb up" the data protocols.
- If data roaming is on, the indication on the top right corner will be 4G, LTE, or 5G.
If Data Still Doesn't Work
- Make sure Mobile Data is ON globally.
- Set APN to: mobiledata.
- Toggle Airplane Mode ON → OFF.
- Restart the phone.
- Temporarily force LTE/4G only (some partner networks have roaming issues with 5G).
