Why are my outgoing texts failing?

[jmartinson]

Every text message I have sent today has failed.  Galaxy S4 worked perfectly until this morning.  Restarted the phone and had one succesful outgoing text then all the rest failed.  Took battery out, removed sim card.....still failing.

Try a clearing of the Cache Partition or you might try a Factory Reset..
