I tried to send a text on my LG koodo and I get the message it can not be sent. I removed the battery and reinserted it. I was the able to text then the message returned. Is this signs that my battery is going?
Try texting yourself to see if it's the sending or receiving. Also, unplug the battery and the sim card while the phone is on. Plug back in after 15-20 seconds power on the phone and try again. Give it a star if this fixes the issue.
