Description

CROSS-REFERENCE TO RELATED APPLICATION(S) This application is a continuation application, claiming priority under §365(c), of an International application No. PCT/KR2021/004062, filed on Apr. 1, 2021, which is based on and claims the benefit of a Korean patent application number 10-2020-0051641, filed on Apr. 28, 2020, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety. BACKGROUND 1. Field The disclosure relates to an electronic device supporting a plurality of subscriber identity modules and an operating method therefor. 2. Description of Related Art In a wireless communication system, an electronic device (e.g., a user equipment (UE)) may access to a wireless communication network to use a voice communication service or a data communication service in a predetermined location or while on the move. An appropriate authorization process is required for providing the communication service to the electronic device. Generally, a universal integrated circuit card (UICC) is inserted into the electronic device, and authorization between the electronic device and a mobile network operator (MNO) is performed through a universal subscriber identity module (USIM) installed in the UICC. The UICC may be referred to as a subscriber identity module (SIM) card in case of a global system for mobile communications (GSM) scheme and a universal subscriber identity module (USIM) card in case of wideband code division multiple access (WCDMA), long-term evolution (LTE), and new radio (NR) schemes. If a user of the electronic device subscribes to a wireless communication service that a mobile network operator provides, the mobile network operator may provide a UICC (e.g., a SIM card or a USIM card) to the user and the user may insert the provided UICC into his or her electronic device. If the UICC is inserted into the electronic device, a USIM application installed in the UICC may be executed to use an international mobile subscriber identity (IMSI) value stored in the UICC and an encryption key for authentication so as to perform an appropriate authentication process with the mobile network operator that stores the same values. After the appropriate authentication process is performed, the user may use the wireless communication service. The electronic device may support two or more SIMs, and in case of supporting two SIMs, an electronic device may be referred to as a dual SIM electronic device and an electronic device supporting a plurality of SIMs may referred to as multi-SIM electronic device. The dual SIM or multi-SIM electronic device may support a plurality of SIM and respective SIMs may be related to different subscriptions. A device which transmits or receives a signal related to a plurality of SIM by one transceiver may be referred to as dual SIM dual standby (DSDS) device. If one of the plurality of SIMs transmits or receives a signal, another SIM may be in a standby mode. Alternatively, a device capable of simultaneously activating both SIMs may be referred to as a dual SIM dual active (DSDA) device. The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure. SUMMARY An electronic device supporting a plurality of SIMs may transmit or receive Internet packet data based on any one SIM. For example, the electronic device may select a SIM to transmit or receive Internet packet data based on manual selection of a user. However, there have not been disclosed a technology in which an electronic device selects (or recommends) a SIM supporting a better communication then current communication, for example, high data transmission speed or low latency communication. Aspects of the disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the disclosure is to provide an electronic device and operating method that can change a SIM transmitting or receiving Internet packet data in case that communication better than current communication is executable. Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments. In accordance with an aspect of the disclosure, an electronic device is provided. The electronic device includes at least one processor, wherein the at least one processor is configured to, by using a first SIM among a plurality of SIMs connected to the at least one processor, transmit or receive Internet packet data to or from a first network corresponding to the first SIM, based on a first RAT, when a second SIM among the plurality of SIMs supports a second RAT different from the first RAT, identify whether communi
