Note: Profiles (PDP contexts)
are not restored from these
backups. Host application
software is responsible for this
task if profiles become
corrupted.
Note: <mcc> is three digits in
North America, or two digits
elsewhere.
Note: The OEM must provide a
random and unique MEP lock
code. This is used by the end-
user to unlock the modem.
