Boost Mobile is one of the most popular providers on the Telstra network, and it's no surprise as to why. Its plans are often cheaper than what Telstra itself offers, but you still get access to the entire Telstra network. 

But if you want to get the most out of your phone plan, you may be wondering exactly how Boost stacks up to Big T. To help, we've gone over how the pair compare on key aspects like data, international calls, international roaming, and extras. 

Boost vs. Telstra: Data inclusions


Boost

Boost has a range of 28-day prepaid plans priced between $28 per recharge and $74 per recharge. Most options include bonus data on your first three recharges. Here are Boost's 28-day prepaid plans:

Boost Mobile plans all have 5G, but most are subject to speed caps. Every plan is capped to 150Mbps, other than the $59 28-day recharge, which has a 250Mbps speed cap, or the $74 28-day recharge, which is uncapped. Uncapped plans are able to go as fast as network conditions allow.  

All Boost plans are available as a physical SIM or as an eSIM.

Telstra

Telstra has a much wider range of mobile plans than Boost, spanning prepaid, SIM-only, and phone-with-a-plan categories. You can pay as little as $15 for a seven-day 4GB recharge or as much as $257.29 per month for a 24-month 2TB iPhone 17 Pro Max plan with 300GB of data.

Here are Telstra's SIM-only plans, called Upfront plans. All of these can be paired with a mobile handset (with additional monthly repayments):

#1

All Telstra plans are available as a physical SIM or as an eSIM.

Boost vs. Telstra: Coverage


Boost

Boost is the only Telstra-powered provider (other than Telstra) that has access to the full Telstra network. The full Telstra network covers 2.14 million square kilometres, while the Telstra wholesale network used by other Telstra-powered providers such as Belong, Superloop, and ALDI covers 1.4 million square kilometres. Boost also has access to Telstra's 5G coverage. 

Telstra

Unsurprisingly, Telstra also has access to the full Telstra network for its plans. As aforementioned, this covers 2.14 million square kilometres.

Boost vs. Telstra: Phones


Boost

Boost doesn't sell phones on a plan. It does, however, have a whole range of refurbished devices available outright, such as the iPhone 11, iPhone 12, iPhone 13, iPhone 14, iPhone 15, and Samsung Galaxy S24. All refurbished devices bought through Boost include a free $39 SIM card. 

Boost started selling refurbished smartphones in 2019, partnering with device supplier Alegre. Alegre says it completes a 72-point check to ensure all refurbished phones perform at a high standard and have enough battery capacity left. In addition, it only sources Australian-compliant phones that have been wiped and cross-checked against a police database.

Refurbished smartphones may have minor cosmetic damage including scuffing or light scratches on the screen, but won't have any cracks.

You can read more about the pros and cons of refurbished smartphones here.

Telstra

Telstra has a wide range of devices available on a plan, including the latest handsets from Apple, Samsung, and Google. These are available on 12-month, 24-month, and 36-month repayment options. Here's a quick look at some of the phones available on a Telstra plan: 

Apple

iPhone 18 Pro 256GB

  • 6.3 inch display
  • Rear Cameras: 48MP, 48MP, 48MP
6 Plans from $132.30/mth
Samsung

  • 128MB int. memory (useable capacity will be less)
6 Plans from $76.19/mth

Boost vs. Telstra: Contracts


Boost

Since Boost only sells prepaid plans, they're all contract-free by nature. You're free to switch up recharges on a month-to-month basis, or leave at any time without paying any early exit fees. Just be aware that if you take up one of Boost's 12-month expiry SIMs, you will forfeit any unused data when you leave, and can't get a refund for any months left in your term. 

Telstra

All Telstra plans are contract-free. That means you can step up or down in plan size, or leave, at any time, without penalty on all Telstra SIM-only and prepaid plans.

If you're on a handset plan with Telstra, you can still leave at any time without penalty, but you will have to pay out the remaining value of your phone.

The 20 countries you can get unlimited calls to are as follows:

Telstra

Telstra prepaid plans with recharges worth at least $44 come with international minutes included. A $44 recharge gets you 300 minutes to Zone 1 countries, 60 minutes to Zone 2 countries, and $5 minutes to Zone 3.  

Zone 1 countries are as follows:

Boost vs. Telstra: International roaming


Boost

Boost has three international roaming packs available for its prepaid customers, lasting up to 14 days. Boost's roaming works in 42 countries. Here are its packs: 

Pack Price Inclusions
Three-day expiry $20 15 mins, 15 texts, 2GB
Seven-day expiry $30 30 mins, 30 texts, 5GB
14-day expiry $40 60 mins, 60 texts, 7GB

Telstra

Customers on Telstra Upfront plans can buy a Telstra International Day Pass if they would like to roam overseas. This gets you 2GB of data and unlimited talk and text for $5 per day when roaming in New Zealand, Fiji, Nauru, Papua New Guinea, Western Samoa, Tonga, and Vanuatu, and $10 per day in more than 70 countries. The international day pass expires daily at midnight AEST.

If you go over your 2GB of daily data, Telstra will bill an extra $10 and a further 2GB of roaming data to your account. This data has a 31-day expiry, and can be used on subsequent days whenever you go over your initial 2GB. 

Telstra prepaid customers have access to roaming packs too. These are as follows:

Pack Price Inclusions
Three-day expiry $10 15 mins, 15 texts, 400MB
Seven-day expiry $15 25 mins, 25 texts, 2GB
14-day expiry $25 50 mins, 50 texts, 4GB

Prepaid roaming packs only cover 35 countries.

Boost vs. Telstra: Data rollover


Boost

All of Boost's 28-day prepaid plans have data rollover. If you recharge before expiry, all your unused data will be added to your next recharge. That means if you get to the end of the month with 1GB left on your plan, you'll get the opportunity to use that 1GB next month only. Beyond that, your data is gone.

Boost's seven-day and year-long recharges do not include data rollover. 

Telstra

Customers on Telstra Upfront plans can't bank any unused data, but the feature is available on prepaid. You can save up to 200GB of unused data, provided you recharge your plan before expiry. Any data remaining at the time of recharge will be automatically moved to your data bank.

Recharges must be a minimum of $10 to qualify, and you'll need to have an active recharge to access your data bank. Your stored away data doesn't expire unless you cancel your service, or switch to another postpaid or prepaid option. 

You can access your data bank even if you move to a lower-cost recharge. 

Data rollover isn't available on Telstra's six-month and 12-month recharges. 

Boost vs. Telstra: Excess fees


Boost

Since Boost mobile plans are prepaid, you simply won't be able to use your data if you go over your allowance. Of course, you won't be charged any excess fees either. Instead, you can choose to either recharge early or purchase a data top-up. You can get a $5 pack for 1GB with a seven-day expiry, or a 4GB pack for $20 with a 28-day expiry. 

Telstra

Telstra does not charge excess fees on postpaid and Upfront plans. If you go over your allowance, you'll have your service capped to speeds of 1.5Mbps. 

Boost vs. Telstra: Free stuff and extras


Boost

Boost plans offer great value and features, but don't have any extras. 

Telstra

Telstra plans used to come with a bunch of extras, but the main benefit you get now is the Telstra Plus perks program. This includes:

  • $15.50 adult movie tickets ($13.50 for child tickets) for Event and BCC cinemas. A $3 surcharge applies for sessions after 5pm on a Saturday, public holidays, and special events
  • Discounted movie tickets for Hoyts, Palace, and Dendy cinemas. Discounts vary based on each cinema's pricing, the day, and time of day
  • Discounted tickets to select sporting events
  • Presale tickets for select concerts and events

As part of Telstra Plus, you'll earn 10 points per dollar spent on your monthly bill. Once you accumulate enough, you can redeem your points for a shiny new gadget or a discount on a pricier, shinier, newer gadget.

The value of a Telstra Plus point seems to range somewhere between 0.3 cents and 1 cent, depending on the item you're after.
