Surprisingly easy to set up and the code examples they provided on their website meant I had it set up in under 10 minutes! (I used the php example) We are a small business and have a branded mobile app from our client management system. When a client is done filling out their digital paperwork, we offer them our app and the option to send an SMS with a download link to their phone. Having this ability has lead to a spike in our app downloads, which is great as we can then engage more frequently with current clients. The pricing is very reasonable and the entire system is just very easy to use. would highly recommend!
