Update: It turns out that the $49 for 2Gb was way too much - my actual usage is less than 700Mb a month.

Instead of the complicated shenanigans below, I now just add $40 of credit once a month, and convert $39 that to 750Mb of data. This means I'm paying just over $480/year, down from $708 on Optus.


I've recently switched my iPhone from an Optus post-paid plan to Telstra prepaid. The primary motivation for the switch was coverage - I work only 500m from my home, and Optus coverage in the area ranges from poor to non-existent - but it turns out that Telstra's pre-paid plans are better value (for my needs) than Optus' post-paid contracts anyway.

On Optus, I was paying $59/month every month. This gave me 500Mb of data, of which I used around 300Mb/month on average. I was also making around 80 minutes of calls per month and sending around 120 SMS/MMS - I could have used around 4 times as much without exceeding my cap. In short, Optus were giving me lots of unneeded credit to spend on calls/SMS/MMS, but not as much data as I would have liked.

By contrast, I'm now paying $12.50/week to Telstra for a service that has ridiculous amounts of calls and SMS - even more than then the ridiculously high Optus cap, which I never managed to get close to using. Importantly, it also has 4 times as much data as the Optus plan did - and even better, the coverage and network quality is so much better than on Optus that there's some chance I might use a good chunk of that data!

Telstra's pre-paid service options are broad though, and it took me a while to figure out exactly what I wanted (even after I had help from workmates who'd made the same transition earlier). Largely this is because adding data onto the account is a separate step from recharging the rest of the account - but also it's not clear when various things expire. This post is my attempt at making it easier for other people to negotiate the maze of Telstra's prepaid options.

In order to end up with this, I have to:

  1. Apply a $60 recharge to one of the prepaid plans - specifically, I choose the "Talk & Text+" plan as it's the closest match to my needs. After applying the recharges, this gives me 300 minutes of calls and 600 SMS to use - as well as $60 credit. This credit can be used once I'd run out of free things - or it can be used for things that aren't covered by the free calls, such as calling Telstra's prepaid service number (Yes, that's right: when I was activating my iPad sim, Telstra charged me $0.25 for the privilege of having them set up another source of income for them - calling Telstra for help from a Telstra service is not a free call)
  2. Yes, I know I said I was paying $50/month and I've just started by paying $60 all at once.
  3. So at this point, I have $60 of credit, and I have insane amounts of free calls/sms, but I don't have any data to use. To get the data, I have to buy a PlusPack - paying for it out of that $60 credit currently in the account. In my case, I choose the $49 pack, which gives 2Gb of data.
  4. At this point, I have: 300 minutes of calls, 600 SMS, 2Gb of data, and an extra $11 credit sitting on my account. All four balances expire in 30 days time. I've paid $1 more than I would have paid on Optus

28 days later, those balances are about to expire, so I go through much the same process:

  1. Pay $60 to add $60 credit to the account. This extends the life of the previous $11 so that it expires on the same day as the new $60 - so I have a total of $71, expiring in 30 days.
  2. Because I've chose the "Talk and Text+" plan, this adds another 300 minutes and 600 sms to those balances - and as with the main credit balance, the life of the existing credits gets bumped to the new expiry date, 30 days from today.
  3. Convert another $49 of credit into another 2Gb data pack. This does *not* extend the life of the previous data pack. However, the new data pack won't be touched just yet, as you still have an existing pack active - you need to exhaust the old pack first. If you're dedicated to getting the best possible value from Telstra you could do your best to suck up the rest of the 2Gb by the time the data pack expires - or you could just let it expire at the end of the day.
  4. At this point, you have 600 minutes (minus whatever you used during the month - so in my case, around 500 minutes) and 1200 SMS (minus whatever you used during the month - again, in my case, that's about 1100 left), 2Gb of data (plus whatever is left in last month's data pack - after my first month, that was a tad over a Gb left), and $22 of credit - all expiring 30 days from today.

28 days later, it's time to renew again - but this time, only a $30 recharge is needed. Added to the existing $22, that's still $3 more than is needed to top everything up by the usual amounts. This only adds an extra 100 minutes of calls and 200 SMS to the balance - but that's going to leave me with around 400 minutes of unused talk time and 1100 SMSes at the end of the 28 days

28 days after that, I'll have spent $150 in 12 weeks (compared with $177 I would have spent on Optus in the same period); I'm left with a large balance of free minutes/SMSes in case my usage ever increases (on the Optus plan, any of the freebies you didn't use within the month just vanished), and if I try hard I might have used at least half of the data provided. After a full year, I'll have paid $637 to Telstra, instead of $708 to Optus. If you recharge every 30 days instead, that would be just $600 (and a tidgy bit more for the extra 5 days).

Sheesh. 900+ words to explain the gymnastics I have to go through in order to save $100/year? If it wasn't for the fact that this also gives me access to a mobile phone network that actually works, it wouldn't be worth it!

PS: I believe my $59 plan was an older version; I believe the current plans give you 700Mb of data for the same price. Optus never bothered to suggest I move onto the better-value plan - and as far as I know the only way to do that would have been to sign another 12 month contract, which I wouldn't be willing to do until they can provide coverage around the area where I live/work. Even so, more data (750Mb) can be had for just $39/month on Telstra prepaid - much better value.
