Hi project manager, 1. Do you want to enhance the stability of your IoT/M2M solution? 2. Do you want to customize it and get your own brand solution? 3. Do you want to make the cost more lovely and get more margin? 4. Do you want to get the 3-year warranty? I'm happy to standby and help you to realize them through our professional product and services. Email me to see what I can do for you, or just 'pick our brains'. :) Thanks & Best Regards, ********************************************** Carla Fang M2M/IoT hardware and solution provider Email:carla@ursatek.com
