Abstract: This application sets forth techniques for cellular wireless network characterization and selection based on wireless device usage, including selection of a public land mobile network (PLMN) and/or a subscriber identity module (SIM) best matched to PLMN characterized performance scores and/or habitual device usage of a wireless device. Network performance scores for multiple PLMNs based on crowd-sourced information are downloaded to a wireless device. The wireless device determines a best match between characterized network performance scores to habitual device usage characterization of the wireless device. A best matched roaming PLMN can be determined for a single SIM wireless device. A best matched SIM paired with a best matched PLMN can be chosen as a primary SIM to optimize roaming performance of a multiple SIM wireless device. Additionally, a SIM, associated with a best matched PLMN, can be recommended for installation to a multiple SIM capable wireless device.
