Course it must a country of that size I'm sure they don't bother to

No they don't, but because of the digital cliff seen
with GSM you either have coverage or you don't.

Nope.

The fact that the underlying data is encoded digitally is irrelevant.

Wrong, as always.

The GSM digital cliff happens because with the GSM system, even
when the base can hear the handset fine, if its too far away as
determined by the round trip delay, it ignores it completely.
