I recently started a new job and I'm finding that in this area, I'm having a hard time sending text messages. They will go through on occasion, but most times take 4-5 attempts to resend after receiving a "message failed" error.
I receive texts just fine - authentication texts from websites are received within 5 seconds, but replying to a personal text that I received doesn't work so well.
I seem to have a reasonable signal, 3-4 bars and signal strength usually stays around -76 to -84 db, so should be plenty to send a text.
I've tried removing battery and sim card, and that didn't help.
