Various IM apps stopped running on Voq

[Guest howard2dot0]

I have a problem that I am hoping someone has the solution to...

I have a Sierra Wireless Voq A10 with which I can surf the web just fine (both WAP and HTML sites), but none of my instant messenger apps seems to work on it (i.e. Agile Messenger, IM Plus, even the builit-in MSN Messenger).

Both Agile and IM+ were able to connect to my AIM, Yahoo, and MSN accounts only the first time I installed them, then after about 15 minutes they all stopped being connected to the servers. I even uninstalled them and reinstalled them again to be sure, and the same thing happens (i.e. only works for 15 min after the install, then quits working.)

Has anyone else had this problem?

Below is my Data Connection configuration:
