Sprint and Verizon text messaging messed up?

i don't know what could be happening, but if your phones are powered off keep them on. but if its another carrier (other than verizon, so like sprint, tmobline, at&t, ect) you can't see if it was sent. you can only see that to verizon. i guess cause its not like a mutual signal. hope this helps, & if the problem persists call customer care.
