Yes, you can switch back from eSIM to physical SIM in seconds, in fact you can even use both of SIMs at the same time, your primary card for calls and message, and the eSIM for internet.
For instance, if you’re traveling abroad, you can get an international eSIM to get cheap mobile data such as Ubigi, then switch to the physical SIM once back in your country and activate your local plan.
In this way, you not only avoid changing physical cards which can cause you to lose your card in the process but also remain reachable by your contacts.
