eight customer support response to my inquiry:
Thank you for your inquiries. Do understand that our plans do include
288mins roaming calls back to Singapore as well and at the destination you roam at!
Before I can proceed answering your questions, first you need to understand the difference between VoLTE vs IDD.
VoLTE stands for Voice over Long-Term Evolution or Voice over LTE. VoLTE offers the possibility to voice call via the LTE/4G* mobile data network. (DATA)
International direct dialling (IDD) calls let you connect to overseas numbers directly. Enjoy all-inclusive IDD Talktime with your overseas friends with our IDD talktime. (IDD)
IDD Supported Destinations:
Australia, Bangladesh, Brazil, Brunei, Canada, China, Colombia, Guam, Hong Kong, Iceland, India, Indonesia, Japan, Korea, Malaysia, Mexico, Mongolia, Myanmar, New Zealand, Norway, Pakistan, Philippines, Puerto Rico, Romania, Taiwan, Thailand, USA – Alaska, USA – Hawaii, USA – United States Of America, USA – Virgin Islands, Vietnam
Just remember this,
VoLTE is using your data so it wont consume your IDD.
