On eligible Vodafone postpaid plans, roaming is A$5 a day in more than 100 destinations, so a week costs 7 x A$5 = A$35 (US$24.62); Vodafone's 7-day prepaid Roaming Add-on is also A$35. Travel periods of 6 to 8 days used a median of 1.38 GB in Bcengi's 2026 sample. Paying as you go, that trip's 1.38 GB costs $2.50 in Indonesia at $1.81/GB, metered by the KB (Bcengi's prices are in US dollars). Bcengi is about 10 times cheaper for this trip.

- Each day costs the same however little data you use that day.
- Prepaid: Vodafone's 7-day Roaming Add-on is A$35 (US$24.62) for 7 GB; the 1-day add-on is A$5 for 1 GB and the 3-day add-on A$15 for 3 GB.
