Next up is Malaysia.
Umesh, thanks for the update. I'm bringing up the Smartone HK roaming issue to T-Mobile folks I've worked with on roaming issues. The way I've gotten it to work more reliably is:
Set phone (if you can) to 2G only: connect to Smartone; verify you have GPRS data (if not ensure you are using fast.t-mobile.com as APN)
Once on Smartone, set phone back to 3G/Auto. I tested this two weeks ago in HK when also seeing similar issues.
On Malaysia (I'm there end of the month) I've not tracked latest on roaming carriers there; if you can comment back once there on who is working for roaming for you it would be helpful for the Wiki.
