IPhone 15 types are activated with the eSIM and do not support a Bodily SIM. Use of an eSIM demands a carrier that supports eSIM and also a wireless services system (which may include limitations on switching services providers and roaming, even following agreement expiration). See your provider for specifics. https://alecs-artistic-phone-cases.printify.me/product/7100937/alecs-swirl-046-phone-case-iphone-15-pro-max
