I received a post pay sim card from True completely out of the blue a few days ago. I had never ordered the thing but I thought I could use it as the instructions indicated it could be enabled for global roaming. I use two different phones and two different sims at the moment for such a purpose.
I called True mobile helpcenter to confirm and the lady told me I had to pop into the True store and they would enable the service.
I went to the shop this afternoon and the counter assistant said this sim could not be used for global roaming, despite it being clearly indicated in both English and Thai in the instructions, and contradictory to the True helpcenter.
I thanked the lady, made my excuses and left.
