There is no such thing as GSM gateway fraud. It is the cell phone carriers who are calling it as a gateway fraud. There is a gadget that is called a GSM gateway, which is basically a cellphone (GSM module), that can connect to the internet. What it does is to help you save international long distance calls, by using the internet. Of course the cell phone carriers are not happy about it since they can no longer earn money from your international long distance calls. That is why cell phone carriers will say that it is a "GSM gateway fraud". If it is true that GSM gateway calls are fraud, then internet is also a fraud, VOIP calls are also fraud, since they bypassed the international gateways of local carriers, that includes cell phone carrier and PSTN carriers.
