Ranking explained
How SimBuddy ranks every deal.
Each deal gets a SimBuddy score out of 100, computed from 8 objective factors. Weightings adjust for whether you’re browsing domestic plans, travel eSIMs or in-store starter packs. Affiliate commissions are never a factor. Every deal card can be expanded to see the exact breakdown behind its score.
The 8 factors (domestic weighting shown)
Value ($ per GB)
35%Lower is better. Log-scaled so a single cheap outlier can't dominate.
Coverage
25%ACCC population coverage. Telstra 5/5 · Optus 4/5 · Vodafone 3/5. MVNOs inherit their host.
Data allowance
15%More GB = more score, capped at 200GB so unlimited plans don't run away with the axis.
Affordability
10%Absolute price. Complements $/GB — some users have a hard monthly ceiling.
Speed tier (5G)
8%5G scores 1.0, 4G scores 0.6. Unknown is neutral.
Extras
5%Personal hotspot + international calls. Each worth half.
Freshness
2%How recently SimBuddy verified the deal is live and priced correctly.
Duration fit
0%Travel only (20%): how close the plan length matches your trip length.
Travel eSIMs reallocate 20% to Duration Fit (how close the plan matches your trip length). Starter packs put 15% on Freshness (in-store availability).
Badges awarded from the score
Editor's Choice
Highest overall SimBuddy score in its category — the best mix of value, coverage, data and features across all 8 ranking factors.
Best Value
Lowest $ per GB in its category, and at least 5% better than the runner-up. The clearest value winner.
Best Unlimited
Highest SimBuddy score among unlimited-data plans in the category.
Best 5G
Highest SimBuddy score among 5G plans on Telstra or Optus wholesale networks (coverage 4/5 or better).
Best for Travel
Highest SimBuddy score for travel eSIMs. Weighting favours data allowance, duration fit and freshness.
Cheapest
Uniquely lowest absolute price in its category. Trade-offs (less data, older network) are separate axes on the score.
Popular
Editorial pick — the only badge not computed from the data. Does not affect ranking order.
Plan basics
Prepaid vs Postpaid — which suits you?
Every Australian mobile plan falls into one of two billing types. Understanding the trade-offs saves money and stress — your usage pattern matters more than the price on the sticker.
Pay before you use
Prepaid
You buy a set bucket of data + calls upfront, valid for a fixed window (usually 28 or 365 days). No credit check, no lock-in — when the credit runs out you either recharge or move on. Australia is one of the largest prepaid mobile markets in the world.
Pros
Zero commitment
Cancel or switch any time — no exit fees, no contracts.
Predictable cost
You know the monthly bill before it hits your account.
No credit check
Great for travellers, teens, casual users, or anyone rebuilding credit.
Cheapest entry point
Prepaid deals under $20/month exist across every network.
Cons
Manual recharge required
Auto-recharge is available but many users still get caught with 0 credit at the worst moment.
Fewer perks
Streaming bundles (Netflix, Optus Sport) are usually postpaid-only.
No handset payment plans
Prepaid = SIM-only. Buy your phone separately or outright.
Pay after you use
Postpaid
You use first and pay at the end of the month — a rolling arrangement. Postpaid plans in Australia are typically 'month-to-month' now (no 12/24-month lock-in) unless you bundle a handset. Ideal if you want extras, streaming perks, or a phone on payments.
Pros
Perk-rich plans
Free streaming, unlimited data, roaming inclusions — postpaid gets all the shiny extras first.
Handset finance available
$0 upfront + monthly payments on the latest iPhone / Samsung is a postpaid-only trick.
Never 'run out'
Data caps typically slow you down instead of cutting you off — hard to be caught short.
Priority support
Postpaid customers usually get faster carrier support and a real account manager.
Cons
Credit check required
Denied applicants have to go prepaid. Impacts your credit file if you default.
Bill surprises
Excess-usage charges, roaming, calls to premium numbers — all easy to trip over.
Harder to cancel mid-cycle
You'll pay to the end of the billing month even if you leave day 1.
Lock-in for handset plans
Bundle a phone and you're on the hook for 24-36 months of payments.
