I can find no outage in that location. If you have an android device, can you verify mobile network is checked (home/menu/settings/wireless & networks/mobile network). A lot of times that gets unchecked for some reason.
Ok. Then please remove/replace battery. You can of course try update profile like @JEALLEN65 said - that's a good step that does fix it a lot of the time. If it's still giving you trouble, please private message me and I'll send a refresh to your device.
