Abstract: Implementations of the subject technology provide for storing a temporary certificate on a mobile device for accessing services in association with a primary number. A device determines that a first subscriber identity module (SIM) card, previously used by the device, is not available for use by the device. The device determines that a second SIM card is available for use by the first device within a predetermined time period after the first SIM card is determined to be not available for use by the device. The device confirms that a communication identifier of the first SIM card is strongly tied to a user account associated with the device. The device stores a temporary certificate that attests to continued ownership of the communication identifier by the device and allows the device to access at least one service in association with the communication identifier.
