This is the important bit in your logs:

^^^^^^^^^^^^^^
Try setting the SIM card's PIN with 'ifconfig umb0 pin xxxx'.
On my laptop I have this in /etc/hostname.umb0 (with the correct
pin instead of 0000 and the correct APN):
pin 0000
apn myapn
roaming
down
With this in place running 'ifconfig umb0 up' is enough to get link.
