It sounds like there are two plausible scenarios here. If it really is what it seems, and his wife keeps calling him at extremely bad times, it shows that they both have very poor judgment and is absolutely cause for concern. As president, would he be taking calls from the wife during important meetings with world leaders? How much influence would she have over his decision making? And what does that say about his spinal fortitude?
If, on the other hand, this is a method of damage control whereby his staff keep calling him to stop him from saying something potentially damaging, it is still in poor taste. It makes him look bad as per the first scenario above, it makes his staff look foolish (there have to be better ways to alert him, I would hope; a discrete earpiece would be less damaging, in my eyes, than blatantly taking a phone call), and it leads one to wonder just how strong his leadership abilities really are.
Either way, it reflects very poorly on his ability to lead this country.
