I talk to my kids daily. At a minimum I speak with each of them via phone each night. Two of four have their own cell phones so usually I can talk to the younger two through the older two. Some nights, like last night, the two oldest are away from the youngest. I texted my X asking her to have them call. After 30 minutes they didn't so I called the home phone and talked to them that way.
The two oldest text me daily and will call when they need to talk. If my X takes away their phone they will call me from another phone to let me know. She sometimes gets perturbed that they call but the two oldest are very good about standing up to her over it.
Worst case scenario for me contacting them at night is to call the X's phone. That doesn't happen very often.
