What is the best SIM-only plan for very small businesses?
Quick answer: For teams of 1–5 people, the “best” plan usually isn’t the one with the most data - it’s the one that matches how much data a small team actually uses, without locking you into a long contract. Goodtel’s SIM-only plans start at $24.95 (ex GST) for 10GB, run on the Telstra Wholesale network (so you get Telstra-grade coverage), and come with flexible, no-lock-in contracts - making them a strong fit for small businesses that don’t want to pay for data they’ll never touch.
Why very small businesses are often overpaying for data
Most business SIM plans from the big telcos are built around big data allowances - 50GB, 200GB, even 400GB - because that’s where the margin is. But a 1–5 person business (say, a tradie, consultant, or small NFP team) checking email, using maps, and taking calls on the go typically uses a fraction of that.
Paying $50–$85 a month for 200–400GB you’ll never use isn’t better value - it’s just bigger. For very small teams, the smarter move is matching the plan to actual usage and pocketing the difference.

Why Goodtel works well for very small teams
- Right-sized data, right-sized price. At $24.95 ex GST for 10GB, Goodtel is built for teams that need reliable connectivity without paying for unused data headroom.
- Telstra Wholesale network. Same underlying mobile network as Telstra, so coverage and call quality hold up - including outside major metro areas.
- Flexible contracts. No long lock-ins, so a growing or changing small business isn’t stuck if its needs shift.
- A telco with a purpose. Goodtel is an Australian B Corp that donates 50% of profits to charity and is carbon neutral - for NFPs and values-driven small businesses, switching providers becomes a way to support the sector rather than just a cost decision.
When a bigger plan makes more sense
Not every small business fits the 10GB profile. If your team regularly does heavy data tasks on mobile - large file transfers, frequent video calls without Wi-Fi, tethering laptops in the field - a mid-tier plan with more data will serve you better than repeatedly hitting a data cap. The point isn’t “smallest plan wins,” it’s picking a plan that matches actual use.
