How to Choose the Best Business Mobile Plan for Your Team

Author : Andrew Johns | Published On : 17 Aug 2026

At Ecomms, we always advise our customers to choose plans that would match their team's needs. For example:

Let’s assume your team has 5 employees and each uses about 10–15GB per month. They all use about 50–75GB. Then you should go for plans offering that usage level. 

If usage varies widely, some using less or more data, compare pooled-data plans. Multiple employees share a single data allowance rather than having separate limits. 

For example, a provider might offer 60GB for five employees if they use a combined 60GB per month. That way, all workers have access to data, and those who need more can use more while others use less, avoiding wastage. 

If employees work in regional areas, check whether the provider's network covers that location before choosing the plan. If they travel overseas, compare international roaming costs.

A cheap plan can end up costing more if your staff run out of data, lose coverage at work sites, or spend time dealing with billing and support issues. The right business mobile phone plan in Australia should match how your team actually works. 

For most businesses, the key factors are coverage, data use, number of employees, contract terms, support and total monthly cost.

1. Start with how your team uses mobile phones

Your team's mobile usage should be your priority. Because it tells you how much data, calling, and your business actually needs. Or flexibility to change plans when needed, share data, add or remove SIMs, etc. 

Ask:

• How many staff need a business SIM? 

• How much data does each person use? 

• Do employees work in an office, at home or in the field?

• Do they travel around Australia?

• Does anyone travel overseas?

• Do staff use their phones for video calls or large file transfers?

• Do you need SIMs for laptops, tablets or hotspots?

• Do some employees use far more data than others?

Let us assume you have a team of 5 and some use 10GB, others use more, say 40GB. Using the same plan for everyone may not give some the needed data allowance. 

For some, it might not be enough. You might need a plan where everyone can use the data they need to work. 

2. Check mobile coverage where your team works

A plan is only as useful as the network coverage it has in your area. It is no good if your staff cannot get a reliable signal where they need it.

Check coverage at:

• Your main office

• Employees' regular work locations

• Customer sites

• Warehouses

• Construction sites

• Regional areas

• Places where employees travel regularly

Australian authorities require mobile network operators to publish 4G and 5G coverage maps using common coverage categories. Australia introduced that rule in 2026. Also, they must update the maps at least every three months.

So you can use that to check if your area has network coverage. Also, in areas with local conditions like buildings, terrain, trees, etc., these can affect real-world service. 

So verify whether any of your team members work in remote areas and check coverage at their regular work locations. Do that before moving the entire team to a new provider.

3. Work out how much data you really need

It is a waste of money to pay for more data your team doesn’t fully use. Let’s say you have a team that uses 10GB per person; paying for a much larger allowance may simply increase your monthly bill and also lead to unused data. 

Look at your recent bills and group employees by usage.

These are general examples. Actual usage should determine the plan.

The goal is to match the plan to actual behaviour. So you know if you need a small, medium or large data plan. 

If you need to roll over data for employees who usually have unused data. Or you need to make an additional data purchase after they exhaust their data.

4. Decide between individual and shared data

Some businesses assign data allowance to each employee. Others use a data-pooling plan, in which several SIMs for workers share a common allowance.

Individual data plans

These can work well if you know how much data each of your employees uses monthly. For example, if each of your workers uses roughly the same amount of data every month, individual plans are easy to manage.

Data pooling

Pooling makes sense especially when workers use varied amounts of data over time. 

Suppose you have a team with 10 SIMs. Three employees use very little data. Two use a lot. The remaining five do not use much. You can set a data plan for each; some may exceed their usage, while others might not even use all of the data. 

In that case, using a shared data pool allows the team to use a single allowance across multiple SIMs. For example, eComms offers 4G and 5G data pooling business mobile plans, with options ranging from 10GB to 60GB.

Note:  Pooling is not automatically cheaper. Compare the expected total usage with the actual allowance and price.

5. Consider data rollover if usage changes each month

When workers do not finish their data on time, it can be carried forward, depending on the plan's rules.

For example, eComms offers 4G and 5G business mobile plans with data rollover, with options ranging from 10GB to 180GB. It also offers data pooling plans for teams that need to share data.

Always ask your provider or check for rollover rules. Also check how much can be carried over and when it expires.

6. Check the contract before you sign

Do not get carried away with cheap plans; always check the contract before signing. Look for things like:

• Minimum contract period

• Early termination fees

• Plan change fees

• SIM replacement fees

• Activation costs

• Excess data charges

• International roaming costs

• International call charges

• Equipment costs

Australian telcos are required to provide a Critical Information Summary (CIS) for their products and plans. It contains important information, such as inclusions, exclusions, fees, contract terms, and roaming costs.

Read the CIS before agreeing to a plan. So you do not rely on sales claims.

7. Look at international use if your team travels

Do not choose a plan based only on Australian use if your employees travel overseas.

If you have workers who travel a lot, then they need plans that support international roaming. Before going for the plan, ask:

• Which countries are covered?

• Is roaming included?

• Is it charged per day?

• Are there data limits?

• What happens when the limit is reached?

• Are international calls included?

• Can roaming be turned off for some employees?

8. Check whether you need mobile broadband

Your mobile SIM is for calling and connectivity for: 

• Laptops

• Tablets

• Mobile hotspots

• Field equipment

• Temporary work sites

In this case, you need data for online communication, collaboration and other work-related activities. So a data-only mobile broadband plan may be more suitable.

For example, eComms offers mobile broadband plans designed for laptops, tablets and hotspots, with data options from 15GB to 400GB.

9. Think about how you will manage the account

Managing more than 1 SIM can be difficult; imagine 20 or more. You need an easy way to manage them. So ask your provider how easy it is to:

• Add a new employee

• Cancel a SIM

• Change a plan

• Replace a SIM

• Transfer a number

• Check usage

• Manage billing

• Get technical support

When you use different providers for mobile, internet and business phone services, it can mean managing several bills and support contacts. It is advisable to use a single provider to simplify this.

For example, eComms manages business mobile services alongside its phone systems, internet and voice services. Its business mobile plans can use Telstra or Optus networks, with the SIMs managed under the same business account.

10. Check whether the provider supports your existing phone system

If you already have a phone system, confirm whether your provider supports it and whether the mobile plan works with it, especially if it is 3CX or Mitel.

For example, eComms supports mobile services alongside 3CX and Mitel MiCollab. This can be useful for businesses that want their mobile and office communications managed together.

11. Compare the total cost, not just the advertised price

Calculate the likely monthly cost for the whole team.

Monthly cost = SIM charges + extra data + roaming + international calls + device costs + other fees

Also consider how easy the service is to manage. 

For example, if you have 10 employees using different mobile services billed separately, checking 10 bills every month can be daunting and time-consuming. If it suits you, choose a provider that combines your services into a single bill. It may be worth considering if the extra cost is reasonable.

12. Choose plans by employee role

Not every employee needs the same plan. They do different jobs. Their mobile needs can be different too.

A simple approach is:

Office staff: Choose smaller plans if they mainly use office Wi-Fi.

Sales staff: Consider more data if they spend most of the day travelling or meeting customers.

Field workers: Prioritise coverage and larger data allowances.

Managers: Consider rollover data if their usage changes from month to month.

Remote workers: Check coverage at their regular work location before choosing a plan.

Travelling employees: Look closely at international roaming.

Laptops and tablets: Consider data-only mobile broadband.

13. Check the network before moving your whole team

Australia has three major mobile network operators: Telstra, Optus and TPG/Vodafone. Other providers use one of these networks. Check which network a provider uses and whether it offers reliable coverage where your employees work.

 

So choose the provider that offers the best service for your workers. Also, check that the network has reliable coverage where your employees work. 

14. Avoid paying for features your team does not use

A business mobile plan can include many features. But only features you need in a plan that are important. 

Before paying more, ask:

Will this feature solve a real problem for my business?

If the answer is no, you probably do not need it.

So, what is the best business mobile plan for your team?

There is no single best business mobile plan for every Australian business. The best plan is one that fits your team size, data usage, work locations, budget and communication needs. 

Choose based on how your employees actually work, rather than on the largest data allowance or the lowest advertised price.

For instance, a small office team may need simple, low-data plans. Whereas a field-based team with many workers, with some not working in the office, may need larger allowances and stronger coverage. 

A business with unpredictable monthly usage may prefer data rollover. Or benefit from pooled data and flexible account management. 

For businesses that want to compare options, eComms offers 4G and 5G mobile plans, data rollover, data pooling and mobile broadband options. Its plans are available on Telstra and Optus networks and can be managed alongside other business communication services.
