Felix Mobile vs TPG Mobile: Unlimited Data Showdown 2026

Updated March 2026 · 5 min read

If you're after a no-fuss SIM-only plan in Australia and the words "unlimited data" have caught your eye, you've probably come across both Felix Mobile and TPG Mobile. They share a surprising amount of DNA — both run on the Vodafone network — but their plan structures are worlds apart. This Felix Mobile vs TPG Mobile comparison breaks down exactly what you get for your money in 2026, so you can stop second-guessing and start saving.

Plans & Pricing Compared

The biggest difference between these two carriers is their approach to data. Felix Mobile offers Australia's only truly unlimited data plan, while TPG sticks to generous fixed-data buckets at competitive price points.

TPG's 50% off promo is genuinely impressive: the Large 100GB plan drops to just $22.50/month for your first six months. That's outstanding value if you can commit to the first half-year. Felix's introductory $20 unlimited rate is equally compelling for the first three months, but once it steps up to $40/month, the value calculus shifts.

Network Coverage: Vodafone with a Twist

Both carriers are fundamentally Vodafone-based — Felix operates purely on the Vodafone 4G/LTE network, while TPG (which owns Vodafone Australia) has added a network-sharing arrangement with Optus that extends coverage into regional areas beyond Vodafone's core footprint.

In practice, Vodafone's network covers around 96% of Australians and performs very well in metro areas — Sydney, Melbourne, Brisbane, Perth, and Adelaide all have solid 4G and 5G coverage. Where things get interesting is in regional and rural Australia. TPG's Optus roaming agreement gives it a meaningful coverage edge outside major cities, making it the smarter pick if you travel beyond the urban fringe regularly.

Felix caps speeds at 40Mbps regardless of conditions, which is plenty for streaming 4K video, video calls, and everyday browsing — but it does mean you're not getting the full benefit of Vodafone's faster 4G or 5G infrastructure. TPG's Large plan lets you hit 250Mbps, which matters if you're tethering a laptop, gaming online, or on a shared hotspot with multiple devices.

Who Should Choose Felix Mobile?

Felix is built for people who hate data anxiety. If you regularly burn through 40–50GB a month streaming music, watching video, using social media, or working remotely, Felix's unlimited plan eliminates the mental overhead of tracking your usage. You'll never get a shock bill or a throttled connection mid-month.

Felix also appeals to environmentally-conscious Australians. The company is carbon-neutral, runs on 100% renewable energy, and plants a tree for every active subscriber every month. If sustainability factors into your purchasing decisions, Felix is the clear ethical choice among Australian MVNOs.

At $40/month ongoing, Felix is priced at a premium relative to TPG's fixed-data plans — but for heavy users who'd otherwise buy the 100GB TPG plan at $45/month, the unlimited ceiling is worth the marginal difference.

Who Should Choose TPG Mobile?

TPG makes the most sense for moderate data users who want more speed headroom and genuine 5G access. If you typically use between 25GB and 80GB per month, TPG's $35/month 50GB plan (or just $17.50/month for the first six months) delivers exceptional bang for buck.

TPG's introductory pricing is among the best in the Australian market right now. Six months at half price gives you time to assess your actual usage before committing to the full rate. And if you exceed your monthly allowance, TPG charges $10 for an extra 2GB — more generous than many competitors who charge the same for just 1GB.

If you're in a regional area or frequently travel outside capital cities, TPG's extended coverage through its Optus network-sharing deal is also a meaningful practical advantage.
