Thanks for the update and glad it worked out for you in the end.
How do you get the pre-paid SIM with more data at a discounted rate from STC? Do you just show them your boarding pass at any shop?
Also, I now make it a point to grab the top 2 or 3 major carriers in a countries APN information online before I go, copy it to a MS word file, and print it out. This after I have asked the reps in shops around the world for their APN information and gotten so many blank stares...
