I have not seen this posted so thought I would ask. We have a new 2014 QX60 and while my wife was trying the SOS button, she was told that this is not a guaranteed service! She thought that the fee after a year was a lot to pay and the rep said that the service is via AT&T 2G network. This 2G service from AT&T will be going away and Infinity has no idea if they will be able to continue this service at all. The dealer made a big deal out of this. Has anyone else heard anything about it and is this service worth it anyway?
