"Hi [insert surname here]! Your friend sent you a message on Cake. https://goo.gl/[some letters and numbers for the link]"

I don't know a single person who would address me by my last name, nor do I know anyone who would use a service to send me a message. A quick Google reveals it's just another scam. Never click links on text messages. It's an easy way for spammers to gain access to your phone and anything stored on it.
