In order to be able to successfully use ProSIM , your mobile phone must be unlocked to allow the eSim functionality to be enabled.
What is an Unlocked Phone?
An unlocked phone is not tied to any specific carrier. That means you can use it with any network, as long as it's technically compatible.
Why Does Having an Unlocked Phone Matter?
Locked Phone = No eSIM Functionality
-
You will be unable to install or activate ProSim
-
Locked phones block ProSim features entirely until unlocked
-
If your phone is locked, you can only use the Sim from the carrier it's locked to
How do I know if my phone is locked?
Sometimes, your phone may be "locked" to your current carrier. This may be the case if you are making payments on the device or if your phone is very new. To check if your phone is locked:
iPhone:
Go into your iPhone’s Settings
Select “General”
Select “About”
Scroll down to “Carrier Lock” and see what it says
“No SIM restrictions” means your phone is unlocked, while “SIM locked” it is.
Android:
Go into your Android phone’s Settings
Select “Connections” (or “Network and Connections”)
From here you can select “Network Operators” and see if multiple networks are available. This would mean your phone is likely unlocked. Otherwise, follow the next steps.
Scroll down and select “More connection settings”
Select “Network unlock” to view your “Network lock status”
This will tell you whether your phone is locked to a specific carrier or unlocked.
