Enable Data Roaming

By now, the eSIM is installed on your phone! You will see the new plan in your Settings with the label you chose. The last step is to make sure Data Roaming is turned ON for the eSIM. (You can turn this setting OFF on your Primary line.) On the same screen, you can select Data Mode, and then select Low Data Mode. This helps to conserve your data by preventing background data usage when the eSIM is in use.

Enable Data Roaming

Connecting to the Internet

After successfully activating your eSIM, your device will begin searching for a signal immediately. In most cases, a data connection will be established immediately, and you will see 5G or 4G LTE in the signal status. This means you are connected and ready to go!

In rare cases, it may take up to 15 minutes for a data connection to be established. Please be patient, as there are many data carriers and environmental factors that can affect the activation time.
