bip: report a location in PROVIDE LOCAL INFORMATION

TS 102 223 6.8.7: TERMINAL RESPONSE shall contain the data object the
command qualifier (6.6.15) asked for.
The card always asks for location information, so at least answer 00,
with the GERAN form of TS 131.111 8.19.1, PLMN 262-01.

Do not answer "terminal currently unable to process - no service"...
