Section 3.1 "Definitions" at the very beginning of 3GPP 23.401: Default APN: A Default APN is defined as the APN which is marked as default in the subscription data [...] when no APN is provided by the UE". UE = User Equipment. The "subscription data" comes from the HSS in the network. In the same spec see also paragraph 12 in section 5.3.2.1. This paragraph has about 5-6 sentences starting with: "If the UE does [not] provide an APN,..." The operator I can connect to using a blank APN did not even exist yet when I bought the phone, so for sure the phone is not sneakily providing any "good default APN" to get me online. It is a old 2.5G EDGE phone by the way. _______________________________________________ networkmanager-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/networkmanager-list
