7 December 2007 John Chan Senior Writer CNET Asia On SIM swapping A couple of weeks back, I took a boat ride to a nearby Indonesian island for a short day trip. On the way there, I noticed more than one passenger swapping out the SIM card on their mobile phones for another one kept in the wallet. That makes perfect sense for those who straddle between two countries for work. You get one operator contract at home and another with a local operator in the other country so you don't incur roaming charges. Now, switching SIM cards can be tricky sometimes.

Those are just the main steps. What I haven't listed out are problems like not having enough hands to handle all that gear (especially when the batteries are removed), the risk of swallowing and choking on the SIM card, and the possibility of a mugger coming forward to relieve me of whatever new, unreleased phone I'm trying out. Imagine, I do this outside of the office only occasionally, but those who travel overseas to work have to swap their SIM card out every single day if they do not want to use two mobile phones.

So far, it's available only in the Philippines, but Verzio says it's in talks with distributors in other countries as well.
