Don't listen to other reviewers, i'm pretty sure they are paid to leave bad reviews. This is a good basic SMS/MMS forwarding app that will forward all your texts to the phone number or e-mail of your choice. If you are having problems with it working, then it's likely an external factor, NOT the app. The app will forward all SMS/MMS messages for free. You can apply only one filter for free: so you can either forward ALL, or you can forward all that are received from ONE contact/phone number/e-mail address. That's it. If you want to add more contacts or customize the forwarding in ANY WAY, you will need to purchase the pro version. I was having problems and about to contact the developers, but I figured it out with a little troubleshooting. I noticed that only SOME of my texts were getting forwarded, but not all of them (even though i applied the "forward all" rule). After some research, i realized that Google Messages now uses RCS when available. So if you're chatting with another user using the same app, the text will be received in RCS format, which is not a format supported by this app. The only way to fix this is to tell the sender to send SMS/MSS format texts. You can't control how a message is received. if it's sent in RCS format, it's received in RCS format. RCS is designed to be more secure, which means the message is encrypted and it's likely the reason that SMS forwarder can't do anything with it. Bottom line: if you're having issues, it's likely due to the fact that the text you're receiving is not in SMS or MMS, it's some other encrypted format. The app is so basic and straightforward that there's literally nothing else that can go wrong; i used all the default settings and it works just fine.
