In which countries can I use my mobile?

AutoRoam™ gives you the freedom to use your BEST telecom mobile in more than 170 countries – as easily as you do at home, day or night. There’s no need for expensive hotel phones or the inconvenience of public phones.

Importantly, your mobile number doesn’t change, which means your contacts can call you without having to remember another number. Depending on your overseas carrier, you may still be able to screen your incoming calls and divert those you don’t want to answer to voicemail.

As an BEST telecom Post-Paid customer on the Optus network, you can:

• SMS ‘A’ to 321 and VoiceMail will call you back (standard roaming charges apply) or
• Access VoiceMail by calling +61 4 1100 0321 (international call charges apply)
• For general or billing enquiries while overseas, please call Optus Customer Care on +61 7 56677119.
• For faults with your mobile phone, you can call +61 7 56677119 (optus 4) for assistance. The Mobile Technical Support Center is open 24 hours a day, 7 days a week.

For your convenience, all your overseas charges are billed back to your Optus account in Australian dollars.
