Can I Use Two eSIMs at the Same Time?

Yes, you can use multiple eSIMs at the same time on several models. These devices allow you to store multiple carrier profiles, but only 2 can be active simultaneously: one eSIM and one physical SIM (on models with a physical SIM slot) or 2 eSIMs (on models without a physical SIM slot). For models with both a physical SIM and an eSIM, you can indeed have 2 active lines at once. Similarly, for phones that support only eSIMs, you can use 2 eSIMs at the same time.

However, while you can have up to 2 active lines, only one line can be used for mobile data at a time, with the other available for calls and messages. Be sure to check that your phone supports multiple eSIMs and is not locked by your carrier, as using 2 eSIMs at the same time for roaming may be subject to limitations based on your carrier and the country you're in.

Troubleshooting Tips

To properly set up your eSIM for data and your SIM for calls, follow these steps.

For iOS Devices:

Open Settings > Cellular or Mobile Data > Ensure both your personal SIM and eSIM are active > Select Default Voice Line > Choose your Personal line > Return to Cellular or Mobile Data > Tap on Cellular Data and select your Holafly eSIM > Locate the Cellular Data Switching option and toggle it off.

Turn Off Data Switch:To use both eSIM and physical SIM at the same time, ensure that the "Data Switch" or "Cellular Data Switching" feature is turned off. This option prevents automatic switching between the SIMs based on signal strength.

For Android Devices:

Open Settings > Go to Connections > Select SIM Manager > Ensure both your personal SIM and eSIM are active > Go to Calls and confirm your personal SIM is selected > Choose Mobile Data and select your Holafly eSIM > Scroll down and toggle off the Data Switching option.
