Yes, this is one of the biggest perks of using SouthESIM! Because our eSIM provides data and uses your phone's digital SIM slot, your physical SIM slot remains free. This means you can keep your home SIM card in your phone. You'll continue to receive calls and SMS messages on your regular number (though your home carrier's roaming rates might apply for these), while enjoying affordable mobile data from SouthESIM for all your internet needs abroad. It's the best of both worlds!
