I have missed alot of important things from using this free man made item. I got the sim card and did everything that I was instructed to do and nothing worked.. its free and unreliable! TEXTNOW needs to rename the app to TEXTNEVER. u never get texts, calls, messages, emails and nothing else.This app is worst than anything I've ever dealt with!! I rather pay for service.my migraines returned after 4yrs. I can't believe someone wasted precious time making this because it wasn't developed.
