I Have the full size, have used it for years. As Rick said I have mine bluetoothed to my cell phone and text off of it. I set up my plan and do the unlimited texts during season and then deactivate it. I have found that clouds, rain and snow interfere with it also trees, can block it. Steep canyons can also affect it. It may not be instantaneous but the next time you use it it might be. It can be noisy at inopportune times. My wife texts me more than I text her is why I use the unlimited plan. The older model is heavier than the Mini should be. Good luck and God Bless
