Short answer: most no-internet cases are caused by the wrong mobile data line, roaming being off, coverage, or APN on Android.
Quick checklist
- Turn off Wi-Fi briefly so you are testing mobile data.
- Select the label used for your 4S eSIM as mobile data.
- If you see several No Number, Travel, Business, or Secondary lines, try the most recently added one first.
- Turn on data roaming for that same eSIM line.
- Restart your phone.
- Try LTE/4G instead of 5G.
- For Android/Samsung/Google Pixel, check APN.
Your phone may not show the name 4S eSIM unless you chose that label during installation. Look for the label you selected, a travel/secondary/business label, or a line that shows No Number.
If you installed more than one eSIM profile
If you installed a duplicate profile or received a replacement eSIM, the newest profile is usually the one that should be used. The older profile may still appear in your phone settings, but it may no longer provide data.
- Open your SIM/eSIM list.
- Choose the newest likely 4S eSIM line.
- Set it as mobile data.
- Turn on data roaming for that same line.
- Test again with Wi-Fi turned off.
Do not delete older eSIM profiles until you confirm which line works or support asks you to delete one.
APN note for Android
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.
