It is not possible to use a stripped version of Iron Socket that you can install for free. You only have the option to go for the three different paid subscription types. This means that you actually always have to reserve an amount to use the VPN service. It is possible to use the service for a very short period of time, but you will have to do this with a detour. There is a 7-day money back guarantee. This means that after the first week you can get out of your subscription and get your money back. It is a way to make short use of VPN, if necessary. Remember that after that you will also completely lose your VPN service. So this is not the same as a free version. At best, it’s a way of doing one or two things online that you can’t do without a VPN without paying.
