Hi everyone,
I know there's a myth that Sprint removed roaming triangle with the latest ROM + PRL. But this is not true.
I just went to Vancouver this weekend, and I was roaming on Canada Talus' network. Magically, the roaming triangle popped out and block data roaming! I was quite happy that Sprint did separate roaming that will induce cost and roaming that won't induce cost. I know when I tried roaming only near the SFO bay area, the triangle doesn't show up.
When I arrived at Portland airport, I don't know which carrier I initially roam to, but I saw the triangle for blink of a sec before it move onto a Sprint network.
Maybe Sprint did a smart thing this time!
