On the theme of communications being a problem...the real problem is that there is too much of it that it has become useless clutter.
To simplify matters:
-Cancel ISP provider
-Cancel mobile phone
-Have one contact phone number in HKG-landline on message bank
-Roster delivered in paper form into mailbox at flight despatch
-Communicate via hand-written fax or better still letter
Problem solved with comms..back to aviate and navigate.
Would probably clog up the system but where in the contract does it state you need to be connected to the internet or have a mobile phone that you pay for?
