Short answer: 4S eSIM provides mobile data. Most apps and websites should work if the local network and destination allow access.
Things that may affect access
- Local network coverage or congestion.
- Country-level website or app restrictions.
- App account security checks when logging in from another country.
- VPN, private DNS, or content filtering settings on your device.
If one app or website does not work
- Check whether other websites load.
- If other websites work, the issue is probably with that app, website, account, VPN, or local access restrictions.
- Turn off VPN temporarily.
- Restart the app and phone.
If nothing loads
- Make sure the eSIM label used for your 4S profile is selected for mobile data.
- Turn on data roaming for that same eSIM line.
- If you use Android, especially Samsung or Google Pixel, check the APN shown on your 4S service page. The important field is APN; Name can be any label you recognize.
- If the APN list is empty, add a new APN, save it, and select it.
- Try switching between 5G and LTE/4G if available.
