I've been having this issue for the last couple months off and on, but for about a week now it's been doing it more often like every single day. I'll send a text to a contact and it will take anywhere from 10 to 20 min for it to send. Sometimes when it's taking that long to send a text, my phone also won't receive texts if they are coming in at the same time. My phone is updated with the current system settings, and I've tried restarting it, taking out the battery, and that still doesn't help it. I always have enough bars, so it's not the signal or anything like that. Any one know why this phone is lagging that much for texting, and how it can be fixed?
