Back home in Oz I logged into my account on several occasions to activate roaming but there is no option available. Tried on Yes my Optus app, no option. Reinstalled app, no option. Logged in online, no option, tried over several days no luck, tried search options and hit links provided but keep getting stupid 'whoops page been moved try again' screen. Got my son (tutors computer science at uni) to help, tells me lve done everything possible, ring CS. Rang CS and rep advised that he has activated roaming. Arrive in Bangkok 3 days ago, phone shows full signal strength, no connection to the network and no 'R' indicator near signal strength icon. Can't text, can't phone. Please Optus what on earth is going on?
In the old web system, the roaming is in between Alerts and PUK in the SETTINGS part.
I the new web system, VIEW DETAILS -> Manage , below nickname
