While part of me thinks that's a good idea as the cost of the hospital phones are so high, and with your own mobile, relatives and friends don't have to keep disturbing the staff, but can you imagine if you're feeling really poorly and you've got someone next to you forever texting and chatting on their phone - nightmare! It's bad enough on a train or bus, but in your hospital bed there'll be no getting away from it, especially if they insist on going through the gory details! I hope it's restricted in some way if it does happen.
