Can de lijn SMS tickets span multiple zones?

Will a 60 min SMS ticket be adequate to take a de lijn bus from Kruidtuin to Zaventem Aeroport? I will use a STIB jump card to get to Kruidtuin, but I suspect it's of no use to connect to a de lijn bus that leaves brussels.

delijn.be doesn't seem to give any indication of where the various "zones" are.

SMS tickets are said to be "unlimited", but it's not clear whether that's unlimited journeys, or unlimited zones, or both.
