Buy SIM card before travel - Travelkon.com

I am the type who would buy SIM card before travelling.

I would also compare shop. Search online. Look on eBay.

But buying international SIM cards online can be a crap shoot, they may not work after installing the SIM card once overseas. It happened a few times to yours truly actually.

With Travelkon, I have been using SIM cards from Travelkon on 4/5 trips already. Have had no problem with the SIM cards at all. All SIM cards from Travelkon just worked. 

Price wise, in line with most places. Difference would be +/- a few bucks. A trick with the website is it often runs sales like 30-40% off. 

If I know I am going somewhere, I would buy the SIM cards in advance.  

Also read the description.. Some SIM cards come with voice. Some are data only. 

One other tip is read the instruction before hand. I remember a country required pre-registration.

Something to note is delivery. The site won't work if you need a physical SIM card and you are flying out tomorrow. The SIM card (physical) will take a week or so to arrive by post (send from Perth apparently).
