lte_lc PDN events for out of cellular range

[0sleep]

If a device has established a PDN connection, is it sufficient to rely on lte_lc's pdn module to determine if a network connection has "failed" due to being out of range, and thereby receiving LTE_LC_PDN_* (etc) events, or must I also monitor for LTE_LC_NW_REG_UNKNOWN / LTE_LC_NW_REG_DENIED events?

It is important to reliably re-connect to the network, as the device is an asset tracker, and will therefore move between cells

Hello,

It is important to reliably re-connect to the network, as the device is an asset tracker, and will therefore move between cells

It sounds like you should check for both types of events then. There is no guarantee that you will receive something like LTE_LC_EVT_PDN_NETWORK_DETACH even though there is a loss of coverage.
