For the last several days, there's a lag with sending (and I think receiving) texts. I'll send a text and it might take twenty minutes or up to a couple of hours for said text to go through. It will just say "sending" on my phone. I've cleared the cache...powered the phone down numerous times and my software is up to date. I've also cleared most of my photos and videos so there's plenty of storage on the phone. Any help would be appreciated.
