Short answer: add or select the APN shown on your 4S service page.
Steps
- Open mobile network or SIM settings.
- Select the eSIM label used for 4S.
- Open Access Point Names.
- If the list is empty, add a new APN.
- Enter the APN exactly as shown by 4S.
- Use any recognizable Name, such as 4S, Travel, or your destination.
- Save and select the APN.
For APN settings, the important field is APN. The Name field is only a local display name and can be anything recognizable, such as 4S, Travel, or your destination.
