Our experts give each plan a score out of 10 - totally fair, with no commercial strings attached.
Telsim's 28-day prepaid plans are fairly average in terms of value for money. They do offer a few handy features like data banking and international calls, which aren't always included on prepaid plans.
Its 365-day mobile plans are better value if you're after a huge chunk of data to last you up to a year.
Telsim's strongest suit is its easy accessibility, being available at most airports in Australia. This makes it well suited for incoming travellers in need of a quick phone connection.
Telsim also sells a number of refurbished Apple and Samsung handsets on its website. These handsets come with a 12 month warranty and are apparently extensively tested, although there are no details of these tests available.

If you're only looking to connect to Telsim over 28-days, it might still be okay, but those looking for long-term value could be better off elsewhere.
The 365-day plan compares well to other big data, but the 180-day plan is quite expensive for what it is.

Telsim has a couple of extra features you can access on its mobile plans.
Some 28-day plans come with unlimited international talk and text to selected countries. The $35 and $45 plans include 10 destinations, while the $55 and $60 plan includes 15. This could be handy perk for those looking to stay in contact with family and friends overseas.
If you'd only like a small amount of international credit, you can get 60 minutes of international calls to 30 countries for $5. These minutes expire when your plan renews.
Any unused data at the end of the month will roll over into a data bank, up to a maximum of 1000GB.
You'll lose this data bank if you downgrade your plan or fail to recharge within 24 hours of your plan expiring. Promotional data does not roll over.
Once you've decided which Telsim Mobile plan you like, you'll simply have to fill out a few details. From there Telsim will take care of the rest. SIM delivery is free via standard postage, but can take up to 10 business days to arrive at your door. Alternatively, you can pick up a Telsim SIM card at local stores and in most airports around Australia.

What if I want to keep my current phone number?
Telsim lets you keep your current number during the SIM activation process. It provides no expected timeframe for the porting process, which usually takes around 48 hours. However, there are a large number of reports online that porting with Telsim could take up to 7 or 14 days to complete.
If your current mobile number isn't registered under your name, it may take a couple more steps. Read our guide on how to change ownership of your mobile number here.
