receiving, from a Mobile Network Operator (MNO), a first Mobile Station Integrated Services Digital Networks (MSISDN) number of a first eSIM profile among a plurality of eSIM profiles in the second electronic device to obtain an operating status associated with the first eSIM profile,

determining that the operating status associated with the first eSIM profile is inactive based on the first MSISDN number received by the server, wherein the server is configured to include the plurality of eSIM profiles and provide an operating status associated with each of the plurality of eSIM profiles in the second electronic device; and

transmitting, to the MNO, a second MSISDN number associated with a second eSIM profile among the plurality of eSIM profiles whose operating status is active based on determining that the operating status associated with the first eSIM profile is inactive,

wherein the operating status of the first eSIM profile in the server is updated from an inactive status to an active status based on determining that the first eSIM profile in the second electronic device is activated.

2 . The method of claim 1 , wherein the MNO is configured to route the call from the first electronic device to the second eSIM profile based on receiving the second MSISDN number with the active status.

3 . The method of claim 1 , wherein the transmitting the second MSISDN number is based on:

fetching an embedded Universal Integrated Circuit Card (eUICC) Identification (ID) associated with the plurality of eSIM profiles using the first MSISDN number as a key; and

fetching, by the server, the second MSISDN number whose operating status is active associated with the second eSIM profile by using the eUICC ID as a key.

4 . The method of claim 1 , further comprising:

after an eSIM profile associated with the MNO is downloaded at the second electronic device, identifying that the eSIM profile associated with the second electronic device is activated; and

creating a table for the eSIM profile to store a MSISDN number associated with the eSIM profile.

5 . The method of claim 4 , wherein the creating, at the server, the table comprises:

generating an One Time Password (OTP) based on receiving the MSISDN number;

transmitting the OTP to the second electronic device comprising the eSIM profile with the MSISDN number;

receiving the OTP from the second electronic device through the MSISDN number and validating the OTP; and

marking the MSISDN number as active in the table associated with the eSIM profile.

6 . The method of claim 5 , further comprising updating the table based on marking the MSISDN number as active in the table associated with the eSIM profile.

7 . The method of claim 4 , wherein the eSIM profile is downloaded from SM-DP+ associated with the MNO.

8 . The method of claim 1 , further comprising:

identifying subscription information associated with the second electronic device, and

identifying, based on the subscription information, whether each of the plurality of eSIM profiles is related to a national MSISDN number.

9 . The method of claim 1 , wherein one of the plurality of eSIM profiles is activated, and

wherein remaining eSIM profiles of the plurality of eSIM profiles are inactivated.

10 . A server for managing a call initiated by a first electronic device and directed to a second electronic device configured to receive the call in an embedded Subscriber Identity Module (eSIM) network, the server comprising a processor configured to cause the server to:

receive, from a Mobile Network Operator (MNO), a first MSISDN number of a first eSIM profile among a plurality of eSIM profiles in the second electronic device to obtain an operating status associated with the first eSIM profile, wherein the MNO is configured to transmit the first MSISDN number upon receiving the call from the first electronic device directed towards the second electronic device on the first MSISDN number;

determine that the operating status associated with the first eSIM profile is inactive based on the first MSISDN number received by the server, wherein the server is configured to include the plurality of eSIM profiles and provide an operating status associated with each of the plurality of eSIM profiles; and

transmit, to the MNO, a second MSISDN number associated with a second eSIM profile among the plurality of eSIM profiles whose operating status is active based on determining that the operating status associated with the first eSIM profile is inactive,

wherein the processor is further configured to cause the server to update the operating status of the first eSIM profile in the server from an inactive status to an active status based on determining that the first eSIM profile in the second electronic device is activated.

11 . The server of claim 10 , wherein the MNO is configured to route the call from the first electronic device to the second eSIM profile based on receiving the second MSISDN number with the active status.

12 . The server of claim 10 , wherein the processor is further configured to cause the server to transmit the second MSISDN number is based on:

fetching an embedded Universal Integrated Circuit Card (eUICC) ID associated with the plurality of eSIM profiles using the first MSISDN number as a key; and

fetching the second MSISDN number whose operating status is active associated with the second eSIM profile by using the eUICC ID as a key.

13 . The server of claim 10 , wherein the processor is further configured to cause the server to:

receive an eSIM profile from the second electronic device, wherein the eSIM profile corresponds to a MSISDN number;

associate the eSIM profile with the MSISDN number by using an eUICC key associated with the eSIM profile; and

register the MSISDN number at the server through an OTP authentication mechanism.

14 . The server of claim 13 , wherein the processor is further configured to cause the server to:

after an eSIM profile associated with the MNO is downloaded at the second electronic device, identify that the eSIM profile associated with the second electronic device is activated; and

create a table for the eSIM profile to store the MSISDN number associated with the eSIM profile.

15 . The server of claim 14 , wherein the processor is further configured to cause the server to:

generate an One Time Password (OTP) based on receiving the MSISDN number;

transmit the OTP to the second electronic device comprising the eSIM profile with the MSISDN number;

receive the OTP from the second electronic device through the MSISDN number and validating the OTP; and

marking the MSISDN number as active in the table associated with the eSIM profile.

16 . The server of claim 15 , wherein the processor is further configured to cause the server to update the table based on marking the MSISDN number as active in the table associated with the eSIM profile.

17 . The server of claim 15 , wherein the processor is further configured to cause the server to:

identify subscription information associated with the second electronic device, and

identify, based on the subscription information, whether each of the plurality of eSIM profiles is related to a national MSISDN number.

18 . The server of claim 10 , wherein one of the plurality of eSIM profiles is activated, and

wherein remaining eSIM profiles of the plurality of eSIM profiles are inactivated.
