A business mobile bill comparison is the quickest way to find out whether your business is paying for data it never uses, or running out of data on the lines that need it most. Most businesses don’t look closely at their mobile bill. It arrives, it gets paid, and the plans stay the same for years. This article walks through how we compare a bill from another provider, what we usually find, and what a switch to Comstel ICT business mobile plans on the Telstra Mobile Network can look like in real numbers.
Key takeaways
- A business mobile bill comparison looks at what your team actually uses, not just the price on the plan name.
- In this worked example, a 10-person business moves to Comstel ICT business mobile plans on the Telstra Mobile Network and pays $180 less per month (ex GST), while getting more data on every line.
- Over a 36-month term, that adds up to $6,480 saved (ex GST).
- Services activated between 12 November 2026 and 3 February 2027 on eligible 45GB–180GB plans also get double data for six months.
Note: the business in this article is an illustrative example based on the kind of bills we review every week. The Comstel ICT prices are our current published prices. Your own savings will depend on your current bill.
The starting point: a 10-person business on another provider
Our example is a professional services business in Sydney with 10 staff. Some work mostly from the office. Others spend their days with clients, on the road and on video calls. Each person has a business mobile on another provider, all on the same contract that was set up several years ago.
The owner’s main concerns were familiar ones:
- The monthly bill kept creeping up, and nobody was sure why.
- The staff who travel kept running low on data before the end of the month.
- Calls to overseas clients were showing up as extra charges.
- Nobody had checked whether the plans still matched how the team works.
Here’s what the existing bill looked like (ex GST):
| Current plans | Services | Data per service | Price per service | Monthly total |
|---|---|---|---|---|
| Small plan | 6 | 40GB | $65.00 | $390.00 |
| Large plan | 4 | 100GB | $85.00 | $340.00 |
| Total | 10 | 640GB | $730.00 |
That’s $730 per month ex GST, or $803 including GST, for 640GB of data across the team.
How our business mobile bill comparison works
A good bill comparison is more than matching one plan name to another. We look at four things.
1. What each person actually uses
We look at data, calls and texts line by line. In most teams, a few people use far more data than everyone else, and several people use very little. When everyone is on the same plan, the light users are paying for data they never touch, and the heavy users run out.
2. Where the extra charges come from
We check for international calls, roaming, add-ons and one-off fees. These often explain why a bill is higher than the plan prices suggest.
3. Contract dates
We check when each service comes out of contract, so you know when you can switch and whether any early exit costs apply. We’ll tell you plainly if it makes more sense to wait.
4. The right mix of plans
Finally, we match each person to a plan size that suits how they work, and choose the term that gives the best price. Our 36-month plans have the lowest monthly rate, and the same plans are available on 24-month or month-to-month terms if you’d prefer more flexibility.
What we found on this bill
The review showed a clear pattern. The six office-based staff were using well under their 40GB each month. The four travelling staff were regularly hitting the limit on their 100GB plans, especially when they used their phones as a hotspot for laptops at client sites. The business was also paying for international calls to clients in the UK and New Zealand.
In short, the business was paying too much for the light users and not giving enough data to the heavy users.
The new setup with Comstel ICT
We moved the team to Comstel ICT business mobile plans on the Telstra Mobile Network, supplied through Telstra Wholesale. The six office-based staff went onto our 65GB Professional plan, and the four travelling staff went onto our 180GB Premium plan, both on a 36-month term.
| Comstel ICT plans | Services | Data per service | Price per service (36-month) | Monthly total |
|---|---|---|---|---|
| Mobile 65GB Professional | 6 | 65GB | $45.00 | $270.00 |
| Mobile 180GB Premium | 4 | 180GB | $70.00 | $280.00 |
| Total | 10 | 1,110GB | $550.00 |
The new monthly cost is $550 ex GST, or $605 including GST.
The result: lower bill, more data
| Measure | Before | After (Comstel ICT) | Difference |
|---|---|---|---|
| Monthly cost (ex GST) | $730.00 | $550.00 | $180.00 less |
| Monthly cost (inc GST) | $803.00 | $605.00 | $198.00 less |
| Yearly cost (ex GST) | $8,760.00 | $6,600.00 | $2,160.00 less |
| Cost over 36 months (ex GST) | $26,280.00 | $19,800.00 | $6,480.00 less |
| Total team data per month | 640GB | 1,110GB | 470GB more |
Every person on the team now has more data than before, and the business pays about 25% less each month. The travelling staff can hotspot their laptops without watching the counter, and the office staff are on a plan that still leaves plenty of room.
The new plans also include things the business was paying extra for:
- Unlimited calls, SMS and MMS to standard Australian numbers.
- Unlimited calls and SMS to 15 selected countries, including the UK, USA, New Zealand, India and China.
- No excess data charges in Australia. If someone goes over, their speed slows down instead of the bill going up.
- Data sharing across up to 20 eligible plans on the account, and unused data that banks for later (up to 500GB).
- 5G speeds up to 150 Mbps on the 65GB plan, and up to 250 Mbps on the 180GB plan.
Limited-time offer
Double data for six months: switch between 12 November 2026 and 3 February 2027
If a business like this one makes the switch during our current offer, the savings come with even more data. Eligible 5G Mobile and Data Only plans from 45GB to 180GB that are activated or upgraded between 12 November 2026 and 3 February 2027 get double their included data for six consecutive billing cycles.
For our example business, that would mean:
- The six 65GB Professional services get 130GB each per month.
- The four 180GB Premium services get 360GB each per month.
- The team’s total data goes from 1,110GB to 2,220GB per month for six months, at the same $550 per month ex GST.
The extra data is applied automatically to each service’s Data Bank, starting from the billing cycle after activation or upgrade. There’s nothing to claim. After six months, each service goes back to its plan’s standard data allowance, and the price stays the same.
Double data on each eligible plan size:
| Plan | Standard data | With double data (6 months) | Price (36-month, ex GST) |
|---|---|---|---|
| Mobile 45GB Starter | 45GB | 90GB | $40.00 |
| Mobile 65GB Professional | 65GB | 130GB | $45.00 |
| Mobile 100GB | 100GB | 200GB | $50.00 |
| Mobile 120GB | 120GB | 240GB | $60.00 |
| Mobile 150GB | 150GB | 300GB | $65.00 |
| Mobile 180GB Premium | 180GB | 360GB | $70.00 |
The offer doesn’t apply to Mobile Pooling or Data Only Pooling plans, or to services activated or upgraded outside the offer dates. Services already on an eligible plan before 12 November 2026 need to complete a qualifying upgrade during the offer to receive double data.
What the switch involves
Moving a team’s mobiles is simpler than most owners expect. Here’s how it usually works with Comstel ICT:
- Send us your latest bill. A PDF of the most recent bill from your current provider is enough to start.
- We do the comparison. We review usage line by line and send you a side-by-side comparison with a recommended plan for each person.
- You choose the term. 36-month for the lowest price, 24-month, or month-to-month.
- We move your numbers. Your team keeps their existing mobile numbers. We coordinate the port and the SIMs or eSIMs.
- One local contact. After the switch, you deal with our team in North Sydney for changes, new lines and support.
