On a recent trip to Taiwan I was not able to use the Starhub prepaid data roaming service. I followed all of the instructions in your guide (here: http://www.starhub.com/content/dam/starhub/2018/personal/mobile/mobile-phones-plans/prepaid-cards/ha...), using the Happy Prepaid app. While my phone did connect to the Chunghwa Telecom network, it could not access mobile data.
I'd be grateful if you could help me resolve this ASAP before my next trip.
Thanks in advance.
For prepaid enquiries, kindly call 9850 0000 for immediate assistance.
My sincere apologies for any inconvenience caused.
