This disclosure relates to techniques for selecting a low power measurement mode (LPM mode). A wireless device may enter an idle mode, determine that it is stationary, and enter an LPM mode. In the LPM mode, the wireless device may perform cell measurements at a reduced frequency.

Low power measurements mode

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.

Wireless device SIM activation while roaming

Techniques are disclosed relating to a mobile device blacklisting certain wireless cells. The device may refrain from considering blacklisted cells for cell operations such as reselection and handover. The device may blacklist cells that fail selection criteria or system information decoding. In some embodiments, the device is configured to manage inclusion of cells on the blacklist based on whether the cells are part of a home network (e.g., an HPLMN) for the mobile device. The device may delete cells that are part of the home network from the blacklist after an out-of-service event or may refrain from adding cells from the home network to the blacklist after certain failures, for example. In various embodiments the disclosed techniques may avoid blacklisting desirable cells in certain scenarios while still enabling blacklist functionality. This may improve wireless performance and battery life, for example.
