I'm working on an App for my transport company. We have some trucks that can be started remotely.
So I want an App which allow me to send sms to the truck and schedule them.
This is what I have done.
Even if I schedule, the App sends the sms inmediatly.
I know it is a mess and probably there would be thousand of wrong things, but I would appreciate some help, please.
Thank you so much in advance.
