Help HTC One M8: Unable to send message

[ProStarPlayer]

Hello, I bought this phone on eBay and I am unable to send text messages with it. I can call, but just not text. Each time I try to update the SMSC by dialing *#*#4636#*#* it says Update Error, and when I refresh, it says Refresh Error. And I still can't text. Does anyone know a fix or any tips that could help me out? Thanks!

That's really strange. Did you try factory reset ?

Yea. I'm not sure what else I could do that might work? I don't understand how the calling works but sending text does not? I guess it could have something to do with the SMSC not updating?
