A review of Lycamobile I just posted on an Australian review website, for the information of anyone who, like me, picks up a local SIM when they travel. My Optus one expired (an entirely different and annoying story!) and I thought I would "give this a go". A huge mistake I would recommend others avoid! Turns out it uses the Telstra 2G network but none of that appears on the advertising for the SIM.....
I live in HK and just wanted a SIM for a few days in Perth, mainly for internet. I thought the 24$ deal was acceptable so I took it. Firstly getting the SIM to work at all was TERRIBLE. It requires a phone or an internet connection (which of course I didn't have because THAT WAS WHY I WAS BUYING THE SIM. Then the internet does not work and you have to ring up for settings - and they say they will SMS them but they don't. So I rang up again and they said they would email in 24 hours (hopeless since I was only here 2 days!). So eventually I got them to read the settings to me ... but the internet is SOOO slow it's useless. Drops out all the time (Perth CBD). Utterly useless and very expensive for a couple of days of internet.
I would only get this in Aus if I did a LOT of phone calling; for a smart phone it's useless. Just purchased an OPTUS SIM and will write off the $32 dollars wasted on lycamobile. Never again. Just wanted to warn others.
