    Abstract: Systems and methods are disclosed for de-prioritizing an LTE anchor cell based on NR cell measurements. A UE may register on a first cell of a first Radio Access Technology (RAT), process a configuration message from a network prioritizing an anchor band of the first RAT, perform a first cell reselection from the first cell to a second cell of the first RAT that is in the anchor band, and perform cell measurements on one or more cells of a second RAT. In response to determining that none of the cell measurements for the one or more cells of the second RAT exceeds a threshold, the UE de-prioritizes the second cell in ranked cell prioritization data and performs a second cell reselection from the second cell of the first RAT to another cell of the first RAT based on the ranked cell prioritization data.

    Abstract: Activation or update of a subscriber identity module (SIM) via a roaming cellular wireless network by a mobile device includes the mobile device: determining a country of origin associated with a mobile network operator (MNO) for the SIM, determining a current geographic location of the mobile device, and when the current geographic location of the mobile device does not correspond to the country of origin for the MNO associated with the SIM of the eUICC, presenting an option to activate or update the SIM over a local roaming cellular wireless network. When the option is accepted, the mobile device enables a cellular data roaming capability for the mobile device, activates or updates the SIM via the local roaming cellular wireless network, and, after the SIM is activated or updated, disables the cellular data roaming capability for the mobile device.

    Abstract: A method, a device, and an integrated circuit utilizes a temperature restricted mode. The method includes determining a temperature of the device. When the temperature is below a first threshold, the method includes enabling a first mode comprising select network operations. When the temperature is above a brick threshold, the method includes enabling a second mode comprising disabling the select network operations. When the temperature is above the first threshold and below the brick threshold, the method includes enabling a third mode comprising modifying at least one of the select network operations.
