Network access card switching method and electronic device

A network access card switching method performed by an electronic device configured with a first network access card and a second network access card, wherein the first network access card is a default mobile data card of the electronic device, and wherein the method comprises:

• displaying a dual-card management function setting interface comprising a control;
• detecting a first operation on the control;
• enabling, in response to the first operation, an automatic network access card switching function;
• transmitting a data service using the first network access card;
• determining that a network state of the first network access card meets a first preset condition;
• based on the network state of the first network access card meeting the first preset condition:
• automatically disconnecting the data service transmitted using the first network access card;
• activating the second network access card;
• and
• transmitting the data service using the second network access card;
• determining, after activating the second network access card and transmitting the data service using the second network access card, that the network state of the first network access card meets a second preset condition;
• based on the network state of the first network access card meeting the second preset condition:
• automatically disconnecting the data service transmitted using the second network access card;
• activating the first network access card;
• and
• transmitting the data service using the first network access card;
• after activating the first network access card and transmitting the data service using the first network access card:
• determining that the network state of the first network access card meets the first preset condition;
• and
• suspending, when the second network access card is in a roaming state, the automatic network access card switching function.

A computer program product comprising computer executable instructions that are stored on a non-transitory computer-readable medium and that, when executed by a processor, cause an electronic device to:

• display a dual-card management function setting interface comprising a control;
• detect a first operation on the control;
• enable, in response to the first operation, an automatic network access card switching function;
• transmit a data service using a first network access card, wherein the first network access card is a default mobile data card of the electronic device;
• determine that a network state of the first network access card meets a first preset condition;
• based on the network state of the first network access card meeting the first preset condition:
• automatically disconnect the data service transmitted using the first network access card;
• activate a second network access card;
• and transmit the data service using the second network access card;
• determining, after activating the second network access card and transmitting the data service using the second network access card, that the network state of the first network access card meets a second preset condition;
• based on the network state of the first network access card meeting the second preset condition:
• automatically disconnect the data service transmitted by using the second network access card;
• activate the first network access card;
• and transmit the data service using the first network access card;
• determine, after activating the first network access card and transmitting the data service using the first network access card, that the network state of the first network access card meets the first preset condition;
• and suspend, in response to the second network access card being in a roaming state, the automatic network access card switching function.
