Business Mobile on Australia's Largest Network. Without the Big Telco Price Tag.
Summit’s business mobile plans run on the Telstra Wholesale network — 98.8% population coverage, unlimited national talk and text, and the convenience of managing mobile alongside your internet and phones with one provider.
Overview
Your team’s mobile phones are as critical to your business as your office internet connection. Sales calls, client emails, job management apps, navigation, mobile EFTPOS — it all runs on mobile. The network those phones connect to matters, and in Australia, one network covers more ground than any other.
Summit’s business mobile SIM plans operate on the Telstra Wholesale network, giving your team access to 98.8% population coverage across Australia, including regional and remote areas where other networks fall short. Every plan includes unlimited national calls and texts, with flexible data options to match the way your business actually uses mobile.
What makes Summit different from going directly to a large carrier is what happens around the mobile plan. With Summit, your business mobile sits alongside your internet, your phone system, your 1300 numbers, and your 4G backup — all on one bill, managed by one Melbourne-based support team. No more juggling three or four providers. No more being transferred between departme
Key Benefits
Australia's Largest Mobile Network
Summit’s mobile plans operate on the Telstra Wholesale network, which covers 98.8% of Australia’s population. Whether your team works in the Melbourne CBD, regional Victoria, or remote project sites, they stay connected on the network that reaches further than any other.
Unlimited National Talk and Text
Every Summit business mobile plan includes unlimited standard national calls and SMS. No watching the clock on client calls. No rationing texts. Your team communicates freely without worrying about excess charges on voice and messaging.
Flexible Data Options
- Standard Plans — A set data allocation per SIM, per month
- Banked Plans — Unused data rolls into a data bank so nothing is wasted
- Pooled Plans — Data is shared across all SIMs in your account, so heavy users draw from the same pool as light users
SIM and eSIM Options
Choose between a traditional physical SIM card or an eSIM for supported devices. eSIMs can be activated remotely without waiting for a physical card to arrive — ideal for getting new team members connected quickly or for devices with dual-SIM capability.
One Provider, One Bill, One Support Team
This is Summit’s strongest mobile advantage. Instead of managing separate accounts with separate providers for internet, phones and mobile, your entire business communications stack sits on one account. One bill. One Melbourne-based support team who can see everything. When you call for help, you do not get bounced between departments that have never heard of each other.
4G and 5G Access
Summit’s mobile plans include access to 4G and 5G coverage areas on the Telstra Wholesale network. As 5G continues to expand across Australian cities and towns, your team benefits from faster speeds and lower latency on compatible devices without changing plans.
No Offshore Call Centres
When you need help with your mobile service, you call Summit’s Melbourne-based team. The same people who support your internet and phone system also support your mobile. They know your account, they know your setup, and they resolve issues without transferring you to another country.
Business-Grade Account Management
Summit treats your mobile service as part of your broader business relationship, not as a consumer transaction. You get a dedicated account contact, proactive support, and the flexibility to adjust plans as your business needs change.
How It Works
Choose Your Plan Structure
Decide whether standard per-SIM data, banked data, or pooled data across your team is the best fit. Summit can advise based on your team size and typical usage patterns.
Select Your Data Tier
Pick the right amount of data for each SIM or your pool. Plans are available across a range of data tiers to suit everything from light email-and-calls usage to heavy field-based data consumption.
Order Your SIMs
Choose physical SIM cards or eSIMs (for supported devices). Summit provisions and ships physical SIMs promptly, and eSIMs can be activated remotely.
Port Your Numbers
If your team already has mobile numbers, we port them to Summit so nothing changes for your clients and contacts. Porting is coordinated to minimise any interruption.
Manage from One Account
Your mobile SIMs appear on the same Summit account as your internet, phone system and other services. One login, one bill, one support number.

Use Cases
The Sales Team on the Road
A real estate agency has 12 agents who spend most of their day out of the office — at inspections, auctions and client meetings. Each agent needs reliable mobile coverage across greater Melbourne and regional Victoria, plus enough data for property apps, CRM access, email and navigation. Pooled data plans ensure the heavy data users are covered by the lighter users’ surplus, and the agency manages all 12 SIMs alongside their office internet and FlexPBX on one Summit account.
The Multi-Site Retail Chain
A retail business with eight stores needs a mobile plan for each store manager. Call volumes are high but data usage is moderate — mostly email, messaging and occasional POS troubleshooting. Standard data plans with unlimited calls and texts keep costs predictable, and the managers’ mobiles serve as a backup contact point when store landlines are busy.
The Trades Business
A plumbing company has six vans on the road. Each tradesperson needs a mobile for customer calls, job management apps and navigation. Banked data plans ensure that unused data from quiet weeks is not wasted, and the ability to port existing numbers means customers keep reaching the same tradesperson on the same number they have always used.
The Professional Services Firm
An accounting firm is consolidating its telecommunications. The partners want their 20 office phones, their internet connection, their 1300 number and their 15 mobile SIMs all with one provider. Summit delivers the complete package — FlexPBX, business internet, 1300 number and mobile SIM plans — on one bill with one support team. When the firm calls Summit, whoever answers can see the whole picture.
Frequently Asked Questions
Can I keep my existing mobile numbers?
Yes. We port your existing mobile numbers to Summit at no additional cost. The porting process is quick and coordinated to minimise any interruption.
What is the difference between banked and pooled data?
With banked data, each SIM has its own data allocation and any unused data rolls forward into a bank for future use. With pooled data, all SIMs on your account share a single data pool, so heavy users benefit from the unused data of lighter users. Summit can help you determine which model is the best fit for your team.
Do you offer 5G plans?
Yes. Summit's mobile plans include access to 5G coverage areas on the Telstra Wholesale network. Your team will connect to 5G where available using a compatible 5G device.
Can I use my own phone or device?
Absolutely. Summit's mobile plans are BYO device -- bring your existing unlocked smartphones, tablets or other compatible devices. We supply the SIM or eSIM; you use the hardware you already have.
What is an eSIM and can I use one?
An eSIM is an embedded SIM that is built into supported devices. Instead of inserting a physical SIM card, the eSIM is activated remotely. This is ideal for quick activation and for devices that support dual SIMs. Summit offers eSIM as an option for compatible devices.
How do I manage my mobile account?
Your mobile SIMs are managed alongside all your other Summit services on a single account. You can monitor usage, adjust plans, and contact support through the same channels you use for your internet and phone services.
Is there a minimum contract term?
Summit offers flexible contract terms for business mobile plans. We will discuss the options that suit your business during the sign-up process.
