Part of the problem with getting information out by phone is they are on limited credit and have no way of adding credit to their phones. No electric, no internet, no stores open, you run out of minutes and you are dead in the water so to speak.

I just spoke to an island resident and I made to call to him and he said he can not call out as he is out of credit and no way to add more.

Edited to add:

TelEm/TelCell (according to Laser101) has given subscribers a $5 credit for landlines and cell phones. They also reported they would have a way to purchase additional credit (cash only) within the next couple of days at a stated location.
