The only place on your account where roaming is displayed, is under your add-ons, where in the past couple of months, a "full roaming" option has started to appear.
The normal method for purchasing roaming add-ons since late last year, is by using a link in the welcome text message sent when you first arrive in a foreign country. You must have a local network connection to receive texts abroad and thus be roaming.
I would therefore conclude, that lack of roaming ability is not the problem in your case.
