I get a "update error" when trying to set the SMS service center, how to fix it?

As the title says. I  checked through the website, and I can't find anywhere how to solve this, I can not send anymore text messages, and I did not check calling but I doubt so. The field is empty, but if I tap refresh a small diamond shape appears with a question mark in it; I am using an LG shine plus, if that changes anything

Did you try to manually add a new APN?  Even if one shows, recreate it with all of the required information.

The key for sms is the mmsc which should be set to http://aliasredirect.net/proxy/mmsc . Watch when you type it in as autocorrect can sometimes add a space between alias and redirect which will cause it not to work.

Proxy will be 74.49.0.18 and the port is 80.  Both will need to be entered twice for proper functionality.
