I just activated a $25 data bundle this morning in Singapore. Just arrived in Osaka, Japan and the data roaming doesn't work.
Hi Kaixinc, can you confirm if both you and your friend activated Happy Roam before leaving Singapore? Also, do ensure your phone setting is set to shwap before connecting to our roaming partner in Japan. If it doesn't work, send us a PM https://community.starhub.com/t5/notes/privatenotespage/tab/compose/note-to-user-id/242 with your names and prepaid numbers.
Thank you -Jolene
