When businesses start comparing mobile plans, the conversation almost always circles back to one thing: the Telstra network. It’s Australia’s most extensive mobile network, covering more than 98.8% of the population — from Sydney’s CBD to remote regional towns. The challenge has always been cost. Until now.

Broadconnect’s $25 Telstra SIM plan gives Australian businesses — and individual users — direct access to the Telstra wholesale network at a price that’s genuinely competitive. No lock-in contracts. No hidden fees. And unlike going directly to Telstra, you get the added advantage of a dedicated Australian support team that actually picks up the phone.

In this guide, we break down exactly what’s included in the plan, who it’s right for, and why Broadconnect is fast becoming the go-to choice for business mobile in Australia.

What’s Included in the $25 Telstra SIM Plan from Broadconnect?

Broadconnect’s entry-level Telstra plan — the Telstra S Plan — is priced at just $25 per month and is packed with features that far exceed what you’d typically expect at this price point.

The plan runs on the Telstra 4G wholesale network, meaning you get genuine Telstra coverage without paying Telstra retail prices. Speed caps sit at 100 Mbps download and 100 Mbps upload — more than enough for video calls, email, cloud apps, and general business use.

Why the $25 Telstra Plan Is More Valuable Than It Looks

At first glance, 10 GB might seem modest. But for many Australian business users — field staff who primarily use Wi-Fi, employees on light data tasks, or anyone running a second SIM for business calls — 10 GB per month is plenty. Here’s what makes this plan smarter than the average:

500 GB Telstra Databank

Unused data doesn’t disappear. Broadconnect’s $25 Telstra plan includes a 500 GB databank, meaning any data you don’t use in a given month rolls over and is stored for future use. For businesses with seasonal usage patterns or staff who travel intermittently, this is a significant advantage. Over time, you build a sizeable data reserve — all at no extra cost.

5 GB Data Gifting

Have a team member who’s run out of data mid-month? The plan includes 5 GB of data gifting, allowing you to transfer unused data to another SIM on the account. This kind of flexibility is particularly useful for small business owners managing a handful of staff lines.

Truly Unlimited Calls and Texts

There are no per-minute call charges and no cap on the number of texts you can send. Whether you’re on the phone with clients all day or firing off dozens of messages, the plan doesn’t meter it. Unlimited national voice and SMS is standard.

No Lock-In Contracts

This is a big one for businesses. You’re not signing away 24 months to access the Telstra network. Broadconnect’s plans are month-to-month, so if your business needs change — you scale a team up, a project wraps up, or you need to change plan tiers — you can do so without penalty.

Who Is the $25 Telstra Plan Best Suited For?

The Broadconnect $25 Telstra SIM plan is an excellent fit for:

• Small business owners who want Telstra-quality coverage without Telstra retail pricing
• Field workers who are mainly on voice calls and don’t need heavy data
• Second lines — businesses that want a dedicated work number separate from personal phones
• Remote or regional businesses where Telstra’s network is the only reliable option
• Start-ups and lean teams keeping mobile costs tightly managed
• Work-from-home employees who use Wi-Fi most of the time but need reliable mobile coverage when out

Broadconnect’s Full Telstra SIM Plan Range

While the $25 plan is Broadconnect’s most affordable Telstra option, they offer a full range of plans to suit different data and calling needs. Here’s how the Telstra lineup compares:

* IDD destinations for the L Plan include Canada, China, Germany, Hong Kong, India, Indonesia, New Zealand, South Korea, UK, and USA. The XL Plan adds Bangladesh, Ireland, Pakistan, Singapore, Thailand, and more.

All plans include unlimited national voice, unlimited SMS, 2,000 MMS, and the 500 GB databank.

Why Choose Broadconnect for Your Telstra SIM Plan?

30+ Years of Australian Telecom Experience

Broadconnect has been delivering business telecommunications solutions since 1990. With over three decades in the industry, the company has deep expertise across mobile, VoIP, NBN, enterprise fibre, and cloud communications. This isn’t a startup with a reseller agreement — it’s a business with a proven track record serving Australian companies of all sizes.

100% Australian-Based Support

If you’ve ever spent 45 minutes on hold with a large telco, you’ll appreciate what Broadconnect offers instead: a responsive Australian support team that knows your account. Customer reviews consistently highlight the speed and quality of Broadconnect’s support — with one client noting their calls are answered “within half a ring.”

Zero Hidden Fees

Broadconnect is upfront about pricing. The $25/month is what you pay. There are no activation fees buried in the fine print and no surprises on your first bill. The company publicly states: 0 hidden fees.

Integrates with Your Business Phone System

One of the biggest advantages of choosing Broadconnect for mobile is the opportunity to integrate your SIM plans with your broader business communications setup. Broadconnect also offers hosted phone systems, Microsoft Teams calling, SIP trunking, and VoIP — meaning your mobile lines can work seamlessly alongside your office phone system.

NSW Government Listed Supplier

Broadconnect is listed as a supplier on the NSW Government’s procurement platform, which speaks to the company’s credibility and the standards it meets in terms of reliability and service quality.

$25 Telstra SIM vs. Going Direct to Telstra: What’s the Difference?

A fair question. Why not just go to Telstra directly? The answer comes down to price, flexibility, and service. By purchasing access to the Telstra wholesale network through a reseller like Broadconnect, you benefit from:

• Lower monthly costs with equivalent coverage and network quality
• No lock-in contracts, versus Telstra’s typical 12- or 24-month agreements
• Dedicated account management rather than navigating a large corporate support structure
• Bundling discounts if you also have Broadconnect handling your NBN, VoIP, or phone system

The network signal itself is identical — you’re connecting to the same towers. The difference is the commercial arrangement sitting behind it.

Frequently Asked Questions

Is this a genuine Telstra network SIM?

Yes. Broadconnect operates on the Telstra wholesale network, which uses the same infrastructure and towers as Telstra directly. Coverage is equivalent across the 98.8% of Australia that Telstra’s network reaches.

Can I keep my existing number?

Yes. Broadconnect supports number porting, so you can transfer your existing mobile number across to the new SIM without interruption.

What happens to unused data?

Unused data is automatically banked into your 500 GB databank and available for use in future billing periods. Data does not simply expire.

Is there a contract?

No. All Broadconnect SIM plans are month-to-month with no lock-in commitment.

Can I upgrade my plan later?

Yes. Because there are no lock-in contracts, you can change to a higher or lower tier plan at any time based on your business needs.

Does the $25 plan include international calls?

International calling is not included on the S Plan. If you need IDD, consider the Telstra L Plan ($45/month) or Telstra XL Plan ($65/month), which include unlimited calls to 10 and 15 international destinations respectively.

Final Verdict: Is the $25 Telstra SIM Plan Worth It?

For businesses and individuals who need reliable Telstra-network coverage without paying Telstra retail prices, Broadconnect’s $25 Telstra SIM plan is an outstanding option. The combination of 10 GB data, unlimited calls and texts, a 500 GB databank, data gifting, and no lock-in contract at $25/month is difficult to beat.

When you factor in Broadconnect’s 30+ years of Australian telecom experience, their local support team, and the ability to bundle mobile with your broader business communications — phone systems, NBN, VoIP — it becomes a particularly smart choice for Australian businesses looking to simplify their telecoms while cutting costs.
