Spintel Mobile Review: The Best-Kept Secret on the Optus 5G Network

Let me be direct: Spintel Mobile is an absolute ripper of a find.

If you're on Optus coverage and paying more than you need to for mobile data, you're leaving money on the table. Spintel runs on the Optus 4G/5G network — yes, the exact same network as Optus itself — but at a fraction of the price. And before anyone asks: no, you're not getting a lesser experience. Optus MVNOs like Spintel get the full network, not some trimmed-down version.

What is Spintel?

Founded in Sydney in 1996, Spintel is best known as an award-winning NBN provider that regularly offers some of the best short-term savings on internet plans in Australia. But its SIM-only mobile plans have been quietly building a loyal following of their own — and for good reason.

Operating as an MVNO on the Optus 4G/5G network, Spintel offers no-frills month-to-month plans with included international calling minutes on every plan and eSIM options for those who want to switch instantly.

Coverage: How does Spintel Mobile perform?

As an Optus MVNO, Spintel Mobile runs on the full Optus 4G and 5G network. Australia's coverage landscape has tightened up recently, with Optus and Vodafone running neck and neck, each spanning roughly 1.2 million square kilometres.

Optus holds a slight edge on 4G, reaching 99.1% of the population compared to Vodafone, though both their 5G networks now reach 94.5% of Australians. Plus, if raw performance matters to you, Opensignal data consistently shows Optus pulling ahead of both Telstra and Vodafone on average 5G download speeds.

Spintel is not for you if you need Telstra coverage in remote areas. But for the vast majority of Australians living in cities and regional towns, Optus coverage is excellent.

Plans and Value for Money

All of Spintel's plans are SIM-only month-to-month offerings that come with unlimited national talk and text, no contracts, and generous data portions.

For the cheapest first-year value, there's the $22 Mobile Plan, which comes with 25GB of data. Step up to the top-tier 200GB plan and you get no 150Mbps speed cap — which is genuinely uncommon among MVNOs.

Here's what stands out about Spintel's value proposition:

• 5G access included — not a paid extra
• International minutes on every plan — $50 to $350 worth of call credit included
• No speed cap on top plan — unlike most competitors
• Month-to-month, no lock-in — cancel any time, no fee
• eSIM available — switch without waiting for a SIM to arrive

Data Limits and What Happens If You Run Out

Spintel Mobile does not offer unlimited data. If you go over your included data, you will be charged $10 per gigabyte, up to 10GB ($100 max) before Spintel blocks your data entirely. If you need to get back online you will need to contact customer support.

If unlimited data is a must, you'll need to look at other providers.

International Roaming and Calling

Spintel includes international call credit on every plan — ranging from $50 to $350 depending on which plan you choose. For international roaming while overseas, Spintel offers $5 per day roaming, which is competitive with the market.

Customer Support and Reviews

Spintel might not have the breadth of support options of the big telcos — and has no in-store support — but what it does offer is fairly straightforward and reliable:

• Phone: 1300 303 375 (8am–8pm weekdays, 9am–5pm weekends)
• Online chat and messaging: via WhatsApp and Facebook
• Self-service: the My Account portal and knowledgebase

In terms of reported customer satisfaction, Spintel is performing very well. The Consumer-review website Product Review lists a 4.7 out of 5 rating (from 18,000+ reviews) across all services. There's also a separate Spintel Mobile entry on Product Review, which stands at an impressive 4.9 out of 5 from 4,000+ reviews.

Spintel also scores 4.6 out of 5 on Trustpilot based on over 1,300 reviews.

The pattern is clear: Spintel customers stay because the product delivers and the price is right.

Referral Program: How It Works

Spintel's Refer-A-Friend program rewards existing customers who spread the word. Here's how it works:

• Mobile referrals: The referrer earns $1 recurring credit per month for each successful mobile referral
• NBN referrals: The referrer earns $5 recurring credit per month for each NBN referral
• Credits continue for as long as the referred customer stays active, capped at the referrer's total monthly recurring charges
• The referee must not have been a Spintel customer within the last 90 days
• No limit on how many friends you can refer

The Catch

There isn't much of one. If you need Telstra coverage (remote areas) or you want unlimited data, look elsewhere. But for everyone else in the Optus coverage zone — and that's most of Australia — Spintel is genuinely excellent value.

Should You Switch?

Yes, if:

• You want great value on the Optus 5G network
• You want fast 5G without being locked into a contract
• You're already a Spintel NBN customer and want everything on one bill
• You want included international calling minutes

No, if:

• You need Telstra coverage in remote areas
• You need unlimited data
