A method for switching between different SIM cards for wireless service includes detecting a status of a network used for voice and data and determining if a physical SIM card is a network card in a wireless client. When the physical SIM card is the network card, the method includes determining whether the wireless client includes one or more cloud SIM cards. When the wireless client includes one or more cloud SIM cards, the method further includes detecting a network status of the physical SIM card and assessing whether the network status of the physical SIM card or the status of the network requires using the one or more cloud SIM cards. When the one or more cloud SIM cards are required, the method includes switching the network card from the physical SIM card to the one or more cloud SIM cards.
