When a Physical SIM Card May Still Be Better
A physical SIM card may still be useful if your phone does not support eSIM or if your device is locked and cannot use a travel eSIM.
You may also prefer a physical SIM if you are staying for a very long time and want a local mobile number, depending on your travel situation.
Before choosing a physical SIM, consider whether you are comfortable buying and setting it up after arrival.
