Received two missed calls from this number, but didn't answer. I wasn't familiar the country calling code. Searched on Wikipedia and found the closest match (+1) to be either from Canada or the US. Checked my email and found an email from AustraliaGSM@australiagsm.net. Tried to view the webpage with the domain name australiagsm.net but got an error "404 - The requested resource was not found on this server".
