Will my phone and usual SIM work in Turkey?

Before buying a travel eSIM, check your phone’s exact model and where it was sold to make sure it’s compatible and not carrier-locked. For your usual SIM, ask your carrier if your plan includes Turkey and what the charges are. If you have a compatible dual-SIM phone, you can use a travel eSIM for data while keeping your usual number for calls, depending on your carrier’s terms.
