The twist in Telstra's case, and the reason why this subject requires a post of its own, is that the only suitable product Telstra would currently give you for your NetComm MyZone is a micro SIM intended to be used by iPad devices, whereas the MyZone requires a normal SIM. The MyZone official website (here) claims micro SIMs won't work on the MyZone, not even with a SIM adapter; my experience says otherwise, and here is how I went about it:
That was it: From here the MyZone worked like a charm.
- I bought a prepaid iPad SIM from a Telstra shop and had them activate it for me on the spot (you can also do it over the phone). You can see this product's page here.
- I bought a micro SIM adapter. You can have a look at how one of these things looks like here. These adapters can be bought at many independent phone shops or on eBay (search for micro SIM or micro SIM adapter and you shall find plenty of offers).
You can find instructions from Gizmodo for making an adapter yourself through some simple DIY here.
- I put the Telstra micro SIM inside the adapter and fit that in my MyZone.
- I set the APN on the MyZone to Telstra.internet as per the instructions here (note Telstra advises the use of a different APN on iPads, but their run of the mill APN - Telstra.internet - works well on the MyZone). If you chose to go with another provider then all you need to do is ask them what their default Internet browsing APN is.
As for recharging this prepaid SIM: Telstra's recharge page for their iPad micro SIMS (here) has been designed for iPad browsing; since I don't have an iPad I find it easy to recharge using the Safari browser on my iPhone. Still, there are plenty of other recharge options available for you to use even if you don't have an iPhone, like this other web page here or over the phone.
