Thinking about an iPhone 4 but don't want to sign up for a contract? We've rounded up the available BYO cap deals so you can find the best no-strings plan for your shiny new phone.

Even if you're not thinking of a new iPhone purchase, prepaid caps have a lot of potential advantages if you've already got a phone, or are planning to buy a new one outright. You've got a fixed cost to work with in terms of usage, but you're not committed to a long-term contract.

The downside is that call rates can be higher than if you sign up to a new contract, you'll have to pay for the phone you bring, and depending on rates you may be paying more than with an absolutely pay-as-you-go prepaid scheme. Also, not all providers offer prepaid cap options. (You can avoid some of those issues with a postpaid cap plan; we'll examine those another time. We'll also look at the new range of iPhone-specific plans as they get announced next week.)

In the table below, we've detailed all the prepaid caps that allow you to bring your own phone (sometimes described as SIM-only plans) that we could find in the Australian market. For each, we've outlined the monthly cost and how much "value" this is said to include (though this is sometimes made up of multiple components, not all of which can be "spent" on all possible services). We've also included the flagfall and the charge per minute seconds for calls and for sending text messages, which are a truer indication of the true cost of using those services.

Where providers offer free calls to other users on the same network, we've indicated this. Vodafone and 3, who are both owned by Vodafone, offer cross-network calling for new subscribers as part of their free "same network" deals. We haven't included international call charges, as these vary so much based on where you call.

We've noted how much data is included with the cap and what you'll pay for excess usage. While many smart phone owners find that their data usage is fairly minimal, the excess charges on these plans are often ridiculously high, and many don't offer more than 50MB of data before they hit you with those fees. Boost, for instance, charges $1.32 per 60KB plus a flagfall, resulting in a whopping $22.75 per megabyte charge. Some providers will let you purchase additional data bundles to supplement your usage.

As ever, network reception plays an important role: a cheap deal is worthless if the phone doesn't work where you live and work. If you're switching to a network you're unfamiliar with, ask friends and family for their experience, and pay close attention to online coverage maps. (One advantage of prepaid: if the network turns out to be a shocker, switching is much easier than with a contract.)

Some providers also feature various extras on their plans. 3, for instance, offers a choice of free access to social networking sites or selected news services in addition to data caps. While most providers have a standard 30-day credit expiry, Crazy John's offers longer periods on its more expensive plans.

With most Planhacker columns, there's not an obvious standout. In this case, for anyone using a moderate amount of data, 3 really does stick out from the rest of the pack (including plans from its sibling Vodafone). Its coverage is limited so it won't be an option for everyone, but its charges and allowances for data are much more reasonable for data than anyone else listed.

    I can't see Telstra's cap plans on that list.

    Can't see Optus's special BYO iPhone plans either:

      Ohh, this is non-contract. Ignore me :)

    You've actually listed 3's Post Paid SIM Only caps rather then their PrePaid plans. The SIM Only's are the same as Voda (The whole VHA thing).

    As for 3's PrePaid it's pretty much the same again as Voda's PrePaid options.

      Close but not exact. The above are the SIM Only inclusions. The inclusions are almost the same for PrePaid, just different pricing, and no data. Comes out of the cap charged at different rates depending on recharge.

      3's Prepaid:
      $29 - $150 ($1 per MB)
      $49 - $350 ($0.70 per MB)
      $69 - $550 ($0.50 per MB)
      $99 - $855 ($0.40 per MB)


    Boost is $22.75/MB - WTF! So an average song download is $66? That can't be right...

      I was surprised too -- but yes, that's what you pay if you download outside your assigned limit. So watching the total closely would be wise if you go with that plan. (In practice, I'd recommend against anyone downloading music over 3G -- that's what WiFi is for.)

    I remember when the first iphone came out you could only get it on a contract for the first few months.
    Is this still the case or will you be able to purchase outright from the launch date?

      Hard to tell. The 3GS was offered outright from the beginning, so that may be the case again this time. But we won't know until it shows up on the Apple site or carriers announce outright buy prices.

    Angus,Not exactly pre paid but you can get Vodafone "Sim Only" month to month plans, while not exactly as flexible as prepaid you can get for example @ $55 /month = roughly 500 minutes + 500 megs + unlimited voda to voda and 3 calls.

    I know, slightly off topic...

    If you don't make many calls, and you're a TPG DSL customer, then the TPG PAYG $1/month deal is great.

    I get 150MB included which is plenty for my pitiful iPhone 2G, and after being on the plan for almost 4 months, I've made just over $10 worth of calls. All I see on my credit card bill is $1 a month until they need to top up the $20 account which I'm guessing will in another 3 months or so.

    Another consideration should be Post Paid caps with no contract, such as Virgins $39 smart cap. $195 cap credit per month, 1500 MB monthly data allowance, unlimited standard text in Oz, Rollover unused cap credit to the next month.

    There smart caps are great for people who want more sms and data instead of call allowance.

    TPG can be great value too, although most options are lacking in data allowance. $20 for $300 credit is great value and is what I used untill I got an iphone on the $35 virgin plan (soon to be upgraded to the $39 smart cap)

    If any of these plans include Credit Rollover onto the next recharge period, you need a column for this. I know from working for Vodafone on Prepaid in the past any unused Cap credit will disappear at the end of the 30 days. Knowing which ones allow you to keep the balance of your credit is a useful decision aid.
