Commit 2254bbae31 ("Yet another massive APN list") referencing
CYNGNOS-436 changed the APN for legacy Saunalahti SIM cards (MCC 244,
MNC 21) from "internet.saunalahti" to "internet.saunalahti.fi".
This causes mobile data to no longer work with such SIM cards as the
previous APN was correct.
The APN is also listed as "internet.saunalahti" on the provider site (in
Finnish) for their legacy MNC = 21 SIM card variant:

Saunalahti is a brand owned by Elisa.
Note that "internet.saunalahti.fi" is not the correct APN for any other
Saunalahti SIM card either, so I'm not sure where this incorrect change
originated from.
