Hi Lifehacker, I'm heading overseas for 12-18 months and I'd like to keep my mobile phone number active as it's the failsafe/reset for several online services I use (Gmail, LastPass and so on). I won't be using it for outbound calls, just to be able to receive the occasional SMS or incoming call for verification.

Dear Lifehacker, A friend of mine recently acquired a new phone and had to get a new SIM in the right size. That made me wonder: why do we still use SIM cards? American CDMA phones are SIM-less, so are there any specific reasons why SIM cards are still needed here?

Predicting the future is near impossible -- but that doesn‘t stop us all from having a red hot go. Human beings have been predicting the future since the beginning of history and the results range from the hilarious to the downright uncanny.

One thing all future predictions have in common: they‘re rooted in our current understanding of how the world works. It‘s difficult to escape that mindset. We have no idea how technology will evolve, so our ideas are connected to the technology of today.

One of the minor annoyances of the iPhone 5 is that is uses the nano SIM format, and replacement SIMs are in short supply if you're not buying on contract through a major telco. Amaysim has confirmed it won't have its own branded nano SIMs until November, but the MVNO is offering to hand-cut replacement nano SIMs for any existing customers who have purchased an iPhone 5 outright.

Jetstar's announced its very own SIM for travellers looking to keep their calling costs down as they gallivant between continents. As part of the launch, they're offering the card for $19.25 (down from its $40.25 RRP), excluding $7 (?) for delivery.

Newly launched mobile company Tru offers you numbers for multiple countries on a single prepaid SIM, potentially saving you a fortune on roaming charges and insane data charges. However, the structure of the plans is quite complex, and whether you'll save money might depend a lot on your usage habits.

Nick over at Gizmodo reports on how Optus (and Optus network reseller Virgin) are offering "2-In-1" micro-SIMs for iPhone 4 buyers ahead of the July 30 Australian release. Customers who -signed up for iPhone 4 updates from either carrier can get sent a standard-sized SIM now, which will then be popped out converted to micro-SIM format when they purchase a new iPhone. It sounds like a nifty way to switch phones with minimal fuss, but from a consumer point of view, it's a pretty risky thing to do.
