A system and method enabling eSIM profile switching without SMS channel support. According to at least one example embodiment, in system in which a device has an eSIM that includes a first profile and a second profile, the device switching from attachment to a first network using the first profile to attachment to a second network using the second profile, the second network connecting to a third network over a data tunnel, a method includes extracting, at a policy control device in the third network, information communicated over the data tunnel, the information associated with the eSIM and sending, to an application server, at least a portion of the extracted information. The extracted information includes location information associated with the eSIM. Sending the extracted information serves as a notification to the application server that the eSIM has switched to the second profile.
