I just did a search for this topic on YouTube and every result was the opposite of what I need! I live in a rural area with no mobile phone signal but I do have internet via a series of wifi links. I understand that certain sim cards can be set up to link with the internet to provide phone calls and text messages. In particular I need to receive security codes by text message for things like internet banking. I live in Croatia and am told that the Simpa sim card offers the facility I need but I have no idea how to set it up.
