Further expanding. GPRS Tunneling Protocol (GTP)[1] is what gets used to connected to the provider's data/voice network. This could be over any medium (wifi, GSM, UMTS, or LTE). It's likely this was the cert protecting GTP-C's ipsec tunnel[2] as without the ability to signal, pretty much everything on the network goes down.

As far as I know GTP is only used for data sessions (PDP) contexts. It should not affect handset registration and circuit-switched voice.
