Once you've installed your new eSIM data plan on your Samsung device, this is an important final step to double-check if your data isn't working immediately. 

• Go to "Settings"
• Select "Connections"
• Select "Mobile Network" 
• Go to "Access Point Names"
• At the bottom of the screen, tap "aloSIM"
• Make sure the APN has "alosim" in the Name field, as well as in the APN field

If "alosim" isn't appearing as an option under Access Point Names:

• Select the three vertical dots in the top-right corner
• Choose to create a new APN
• Put "alosim" in the Name field, as well as in the APN field
• Tap "Save"
