Our verdict
Check your Samsung Galaxy S23 in the settings first. If it can add an eSIM and it is unlocked, install the travel eSIM at home and keep your main SIM for calls.
How to check your phone
Dial *#06#: if an EID number appears, your phone supports eSIM. You can also look for an option to add an eSIM in the SIM or network settings.
A travel eSIM only works if your phone isn't locked to your carrier. The quickest test is a SIM card from another carrier: if it connects, the phone is unlocked.
Keep your number while you travel
With eSIM, the Samsung Galaxy S23 can use two lines at once: your main SIM stays on for calls and texts, while the travel eSIM carries your data. Choose the travel eSIM for mobile data in the SIM settings before you land.
