Configuring non-standalone mode for a multi-subscriber identity module user equipment

1. A method of wireless communication performed by a user equipment (UE), comprising:

determining that the UE is operating using a first subscriber identity module (SIM) in a non-standalone mode associated with a first radio access technology (RAT) and a second RAT and that a second SIM has been activated for the UE;

determining, based at least in part on user input, to operate in a single SIM mode where only the first SIM, and not the second SIM, is active;

selectively deactivating the second SIM based at least in part on determining to operate in the single SIM mode; and

maintaining a non-standalone capability, associated with the non-standalone mode, for the first SIM based at least in part on selectively deactivating the second SIM.

2. The method of claim 1 , wherein the first SIM is configured to operate in the non-standalone mode.

3. The method of claim 1 , further comprising:

determining that the UE has a connection with another UE; and

receiving, via a network connection associated with the first SIM, a page associated with the second SIM; and

routing the page to the other UE.

4. The method of claim 1 , further comprising:

outputting a request for the user input, wherein the request permits user selection of whether to operate in a multi-SIM mode, where both the first SIM and the second SIM are active, or the single SIM mode; and

receiving the user input based at least in part on outputting the request.

5. The method of claim 1 , wherein the user input includes a stored user preference.

6. The method of claim 1 , further comprising:

determining that a serving cell of the UE, associated with the first RAT, supports non-standalone operation with the second RAT; and

determining whether to operate in a multi-SIM mode, where both the first SIM and the second SIM are active, or the single SIM mode based at least in part on determining that the serving cell supports the non-standalone operation.

7. The method of claim 1 , further comprising:

determining that a condition, that indicates a threshold volume of data traffic associated with the UE, is satisfied; and

determining whether to operate in a multi-SIM mode, where both the first SIM and the second SIM are active, or the single SIM mode based at least in part on determining that the condition is satisfied.

8. The method of claim 1 , wherein an icon associated with the second RAT remains displayed on a display of the UE based at least in part on a determination that the user input indicates to operate in the single SIM mode.

9. The method of claim 1 , wherein the first SIM and the second SIM are associated with different network operators.

10. The method of claim 1 , further comprising:

determining whether the first SIM and the second SIM are associated with a same network operator,

wherein determining to operate in the single SIM mode comprises:

determining, based at least in part on user input and based at least in part on determining whether the first SIM and the second SIM are associated with the same network operator, to operate in the single SIM mode.

11. A method of wireless communication performed by a user equipment (UE), comprising:

determining that the UE is operating using a first subscriber identity module (SIM) in a non-standalone mode associated with a first radio access technology (RAT) and a second RAT and that a second SIM has been activated for the UE;

deactivating the second SIM based at least in part on determining that the first SIM and the second SIM are associated with a same network operator; and

using, based at least in part on deactivating the second SIM, a network connection, with another UE, to decode a page, associated with the second SIM, and to permit the first SIM to operate in the non-standalone mode.

12. The method of claim 11 , wherein an icon associated with the second RAT remains displayed on a display of the UE based at least in part on the first SIM and the second SIM being associated with the same network operator.

13. A user equipment (UE) for wireless communication, comprising:

a memory; and

one or more processors coupled to the memory, the one or more processors configured to:

determine that the UE is operating using a first subscriber identity module (SIM) in a non-standalone mode associated with a first radio access technology (RAT) and a second RAT and that a second SIM has been activated for the UE;

determine, based at least in part on user input to operate in a single SIM mode where only the first SIM, and not the second SIM, is active;

selectively deactivate the second SIM based at least in part on determining to operate in the single SIM mode; and

maintain a non-standalone capability, associated with the non-standalone mode, for the first SIM based at least in part on selectively deactivating the second SIM.

14. The UE of claim 13 , wherein the first SIM is configured to operate in the non-standalone mode.

15. The UE of claim 13 , wherein the one or more processors are further configured to:

determine that the UE has a connection with another UE; and

receive, via a network connection associated with the first SIM, a page associated with the second SIM; and

route the page to the other UE.

16. The UE of claim 13 , wherein the one or more processors are further configured to output a request for the user input, wherein the request permits user selection of whether to operate in a multi-SIM mode, where both the first SIM and the second SIM are active, or the single SIM mode; and

receive the user input based at least in part on outputting the request.

17. The UE of claim 13 , wherein the user input includes a stored user preference.

18. The UE of claim 13 , wherein the one or more processors are further configured to:

determine that a serving cell of the UE, associated with the first RAT, supports non-standalone operation with the second RAT; and

determine whether to operate in a multi-SIM mode, where both the first SIM and the second SIM are active, or the single SIM mode based at least in part on determining that the serving cell supports the non-standalone operation.

19. The UE of claim 13 , wherein the one or more processors are further configured to:

determine that a condition, that indicates a threshold volume of data traffic associated with the UE, is satisfied; and

determine whether to operate in a multi-SIM mode, where both the first SIM and the second SIM are active, or the single SIM mode based at least in part on determining that the condition is satisfied.

20. The UE of claim 13 , wherein an icon associated with the second RAT remains displayed on a display of the UE based at least in part on a determination that the user input indicates to operate in the single SIM mode.

21. The UE of claim 13 , wherein the first SIM and the second SIM are associated with different network operators.

22. The UE of claim 13 , wherein the one or more processors are further configured to:

determine whether the first SIM and the second SIM are associated with a same network operator,

wherein to operate in the single SIM mode is further based at least in part on determining whether the first SIM and the second SIM are associated with the same network operator.

23. A user equipment (UE) for wireless communication, comprising:

a memory; and

one or more processors coupled to the memory, the one or more processors configured to:

determine that the UE is operating using a first subscriber identity module (SIM) in a non-standalone mode associated with a first radio access technology (RAT) and a second RAT and that a second SIM has been activated for the UE;

deactivate the second SIM based at least in part on determining that the first SIM and the second SIM are associated with a same network operator; and

use, based at least in part on deactivating the second SIM, a network connection, with another UE, to decode a page, associated with the second SIM and to permit the first SIM to operate in the non-standalone mode.

24. The UE of claim 23 , wherein an icon associated with the second RAT remains displayed on a display of the UE based at least in part on determining that the first SIM and the second SIM are associated with the same network operator.
