Abstract
A method at a user equipment to verify enablement of data billing splitting using a virtual subscriber identity module platform (‘VSP’) service, the method including receiving a credential at the user equipment, the credential including an international mobile subscriber identity (IMSI) from a physical universal integrated circuit card (UICC) subscriber identity module (SIM) application; storing the credential on the user equipment; checking, at a VSP service module on the user equipment, whether the credential matches an IMSI of a UICC currently inserted into the user equipment; if the checking determines a match, enabling the data billing splitting; and if the checking determines a mismatch, preventing enablement of the data billing splitting.
