Abstract: Managing network connections at a mobile device comprises: obtaining connectivity data and location data from the mobile device; determining that the mobile device is connected to a current network using an IMSI of a current profile; determining whether the current network is a preferred network and/or whether the current profile is a preferred profile based on the Quality of Experience data and the location data; and instructing the mobile device to connect to the preferred network using an IMSI of the preferred profile in response to determining that the current network is not the preferred network and/or in response to determining that the current profile is not the preferred profile. The mobile device comprises an eSIM comprising at least a first profile. The first profile comprises at least one IMSI. The mobile device is configured for communication with a connection manager which is configured for monitoring QoE data.

Abstract: The invention relates to a method for detecting a failure in a PDP context or an EPS PDN connection. A chip incorporated within or coupled to a device receives from the device a call control PDP context activation type event or a call control EPS PDN connection activation type event. The chip receives from the device an updated value relating to an HFN start PS. The chip compares the last updated value relating to the HFN start PS to a predetermined value relating to the HFN start PS. If the last updated value relating to the HFN start PS is greater than or is less than/equal to the predetermined value relating to the HFN start PS, then the chip detects that the PDP context or the EPS PDN connection has been successfully or unsuccessfully activated respectively.
