Electronic device and method for providing communication service

An electronic device comprising:

• a first transceiver associated with a first cellular communication network;
• a second transceiver associated with a second cellular communication network different from the first cellular communication network;
• a first antenna configured to receive a first signal;
• a second antenna configured to receive a second signal, wherein the first antenna and the second antenna simultaneously receive signals of the first cellular communication network and the second cellular communication network;
• a divider configured to, while the first antenna and the divider are connected, divide the first signal into a first divided signal to be provided to the first transceiver and a second divided signal to be provided to the second transceiver by splitting power of the first signal, wherein a first frequency band corresponding to the first divided signal and a second frequency band corresponding to the second divided signal overlap each other;
• and
• a switch configured to:
• when a first service is provided and a second service is not provided, connect the first antenna to the first transceiver, and
• when the first service and the second service are provided, connect the first antenna to the divider and transmit the first divided signal to the first transceiver and the second divided signal to the second transceiver,
• wherein, when the first service is provided and the second service is not provided, the second antenna is configured to receive a paging signal of the second service and provide the paging signal to the second transceiver such that the electronic device controls the switch to connect the first antenna to the divider for the first service and the second service to be provided through the first signal, based on the paging signal.
