If he is not allowing you any contact at all then no that would not be frivolous. If you are calling all the time and demanding to talk to them constantly, thus interrupting his time with them, then you could have a problem. Your calls need to be reasonable. If you can't work out reasonable open calls, then if you go back to court, the next step will be to put you on a schedule.

If it is "worth it" for you to speak to your children, then it is "worth it" to file the motion. You filing a motion will also put him on notice that you will not take further violations of the order in stride, on other matters.
Your motion for contempt would not be frivolous. With today's technology with cell phone calls and texts, it would be a relatively simple matter to prove your efforts to contact the children through him. If you prevail with contempt, among the other sanctions the court may levy on him is to award you your attorney fees.
