detect presence of a universal integrated circuit card (UICC) storing a physical SIM (pSIM) in the wireless device, wherein the pSIM includes credentials for access to cellular service of a mobile network operator (MNO) in accordance with a cellular service plan;

determine at least one criterion is satisfied for transfer of the cellular service plan from the pSIM stored in the UICC to an eSIM to be installed on the eUICC of the wireless device, wherein the eSIM includes corresponding credentials for access to the cellular service of the MNO in accordance with the cellular service plan;

while wireless connectivity is available to the wireless device via a wireless connection other than via the pSIM:

obtain, from an entitlement server of the MNO via the wireless connection, transfer credentials authorizing transfer of the cellular service plan from the pSIM stored in the UICC to the eSIM to be installed on the eUICC; and

obtain, from a provisioning server of the MNO via the wireless connection, the eSIM;

install the eSIM on the eUICC;

disable the pSIM on the UICC; and

use the eSIM to attach the wireless device to a cellular wireless network of the MNO.

2. The wireless device of claim 1 , wherein the wireless device is further configured to:

transfer one or more user-defined settings from the pSIM stored in the UICC to the eSIM after installation of the eSIM on the eUICC of the wireless device.

3. The wireless device of claim 1 , wherein the wireless device is further configured to:

mark the pSIM as converted; and

display a notification indicating permissibility to remove the UICC storing the pSIM from the wireless device.

4. The wireless device of claim 1 , wherein the wireless device is further configured to:

when the wireless device supports multiple simultaneously enabled eSIMs, enable the eSIM after disabling the pSIM; and

when the wireless device supports at most one enabled eSIM at a time, enable the eSIM before disabling the pSIM.

5. The wireless device of claim 1 , wherein the eSIM provides access to one or more fifth generation (5G) capabilities unavailable to the wireless device via the pSIM.

6. The wireless device of claim 5 , wherein the one or more 5G capabilities include an identity privacy protection feature comprising use of an encrypted subscription concealed identifier (SUCI) in place of an unencrypted subscriber permanent identifier (SUPI) for one or more messages communicated with the cellular wireless network of the MNO.

7. The wireless device of claim 1 , wherein the wireless connection comprises a wireless local area network (WLAN) connection.

8. The wireless device of claim 1 , wherein the at least one criterion comprises the wireless device supports 5G cellular wireless service.

9. The wireless device of claim 1 , wherein the at least one criterion comprises detection of one or more cells of a 5G network associated with the MNO.

10. The wireless device of claim 1 , wherein the at least one criterion comprises determination that the pSIM lacks support for a 5G identity privacy protection feature.

11. The wireless device of claim 1 , wherein the wireless device is further configured to:

enter a monitoring mode after installing the eSIM on the eUICC; and

monitor for receipt of a message from a network-based server of the MNO before disabling the pSIM, the message indicating activation of the eSIM within the cellular wireless network of the MNO is complete.

12. The wireless device of claim 11 , wherein the network-based server of the MNO comprises the MNO entitlement server of the MNO or the provisioning server of the MNO.

13. The wireless device of claim 1 , wherein:

the pSIM includes credentials for access to a home cellular wireless network of the MNO; and

the at least one criterion comprises receipt of a valid request from a user of the wireless device to perform transfer conversion of the cellular service from the pSIM stored in the UICC to the eSIM to be installed on the eUICC.

14. The wireless device of claim 13 , wherein the wireless device is further configured to:

accept replacement of the UICC storing the pSIM in of the wireless device with a second UICC storing a second pSIM in the wireless device after disabling the pSIM, wherein the second pSIM includes credentials for access to a visited cellular wireless network.

15. The wireless device of claim 1 , wherein the at least one criterion comprises a change of the MNO associated with the pSIM.

16. The wireless device of claim 1 , wherein the wireless device is further configured to:

display a notification indicating an option to perform transfer conversion of the pSIM to the eSIM; and

obtain acceptance of the option before obtaining, from the entitlement server of the MNO via the wireless connection, the transfer credentials for transfer of the cellular service plan from the pSIM stored in the UICC to the eSIM to be installed on the eUICC.

17. The wireless device of claim 16 , wherein:

the notification further indicates the option to perform the transfer conversion of the cellular service plan from pSIM stored in the UICC to the eSIM to be installed on the eUICC allows for access to fifth generation (5G) services previously unavailable via the pSIM on the wireless device.

18. The wireless device of claim 16 , wherein the acceptance of the option includes approval of revised terms and conditions for cellular wireless service for use of the eSIM.

19. An apparatus configured for cellular service plan transfer in a wireless device, the apparatus comprising:

at least one processor configured to cause the wireless device to:

detect presence of a universal integrated circuit card (UICC) storing a physical subscriber identity module (pSIM) in the wireless device, wherein the pSIM includes credentials for access to cellular service of a mobile network operator (MNO) in accordance with a cellular service plan;

determine at least one criterion is satisfied for transfer of the cellular service plan from the pSIM stored in the UICC to an electronic subscriber identity module (eSIM) to be installed on an embedded universal integrated circuit card (eUICC) of the wireless device, wherein the eSIM includes corresponding credentials for access to the cellular service of the MNO in accordance with the cellular service plan;
