No Internet After Installing eSIM: Fix Mobile Data & Roaming (Samsung Phones)

If you installed your DataFly eSIM but the internet isn’t working, don’t worry. In most cases, mobile data won’t work because the eSIM is not selected as the Mobile Data line or Data Roaming is turned off (or both). Follow the steps below.

Step 1: Select your DataFly eSIM for Mobile Data

1. Open Settings
   






2. Tap Connections
   






3. Tap SIM manager
   






4. Under Mobile data, select your DataFly eSIM
   

Step 2: Turn ON Data Roaming for your DataFly eSIM

1. Exit SIM manager to go back to Connections

2. Tap Mobile networks
   






3. Turn Data roaming ON for your new eSIM
   

   🔴 Important

   If your eSIM doesn’t have an ON/OFF button, tap on it and then select “All Networks.”

   
   

Done.
