The Galaxy S21 was released at the start of 2021 with 5G capabilities, which means you can now take full advantage of Telstra, Vodafone, and Optus' 5G mobile plans. The S21 comes in several versions, including the S21 Ultra and the mid-range S21+.
The S21 retails for $1,249 but rather than buying it outright you can pick it up on a payment plan from Telstra, Optus, or Vodafone. This lets you pay off the price tag in more affordable instalments.
Choose from the providers below and we'll show you what plans are available. You can switch between S21 models by clicking through the different tabs.
Telstra S21 plans
Secure a Samsung Galaxy S21 with Australia's largest mobile network.
Telstra's plans are more expensive than either Optus or Vodafone. You'll be paying at least $55 for a plan alone, without even adding in the handset repayments. On the other hand, Telstra has quite a few features to justify its higher pricing. These include:
Wide 5G coverage, tied with Optus.
Loyalty reward points with Telstra Plus.
data between plans on the same account.
Zero excess data charges with SIM only plans.
When you've broken your data limit, you'll be able to stay online, but your download speed will be reduced to 1.5Mbps.
Telstra lets you pick between 12 or 24 months for your contract, which will affect the size of your monthly payments (but not the total you pay for the phone). If you cancel early, you simply need to pay off the rest of your handset.
Vodafone S21 plans
For those after the cheapest Samsung S21 phone on a plan, Vodafone is a great choice, even offering decent speeds on their "unlimited" data.
While you won't get as many features with Vodafone compared to the other major providers, you'll still get some solid plans that are cheaper than Telstra's. These are the main features you'll get from Vodafone:
Bundle multiple services together for a discount.
Variable download speed limits up to 25Mbps after breaking your data cap.
Vodafone 5G network is smaller than Telstra or Optus, but it's growing.
Pick between a 12, 24, or 36 month contract with Vodafone. Leaving your plan early will only cost the leftover amount owing on the handset.
Vodafone also has the fastest speed available on "unlimited" data past your cap, with speeds from 2 - 25Mbps, instead of the 1.5Mbps you get with Optus and Telstra.
Optus' data plans have some of the highest data caps you'll see, going from 10GB all the way up to 500GB. Aside from talk, text, and data, Optus has these features:
All postpaid plans come with potential 5G access.
Share data between plans on the same account.
1.5Mbps speed-capped "unlimited" data past your limit.
Contract options with Optus span 12, 24, or 36 months. When you cancel early, you'll have to pay out the remaining value of your device. Optus has roughly the same 5G coverage as Telstra.

Important information about this website
finder.com.au is one of Australia's leading comparison websites. We are committed to our readers and stands by our editorial principles
We try to take an open and transparent approach and provide a broad-based comparison service. However, you should be aware that while we are an independently owned service, our comparison service does not include all providers or all products available in the market.
Some product issuers may provide products or offer services through multiple brands, associated companies or different labeling arrangements. This can make it difficult for consumers to compare alternatives or identify the companies behind the products. However, we aim to provide information to enable consumers to understand these issues.
We make money by featuring products on our site. Compensation received from the providers featured on our site can influence which products we write about as well as where and how products appear on our page, but the order or placement of these products does not influence our assessment or opinions of them, nor is it an endorsement or recommendation for them.
Products marked as 'Top Pick', 'Promoted' or 'Advertisement' are prominently displayed either as a result of a commercial advertising arrangement or to highlight a particular product, provider or feature. Finder may receive remuneration from the Provider if you click on the related link, purchase or enquire about the product. Finder's decision to show a 'promoted' product is neither a recommendation that the product is appropriate for you nor an indication that the product is the best in its category. We encourage you to use the tools and information we provide to compare your options.
Where our site links to particular products or displays 'Go to site' buttons, we may receive a commission, referral fee or payment when you click on those buttons or apply for a product. You can learn more about how we make money.
When products are grouped in a table or list, the order in which they are initially sorted may be influenced by a range of factors including price, fees and discounts; commercial partnerships; product features; and brand popularity. We provide tools so you can sort and filter these lists to highlight features that matter to you.
