Problems sending and/or receiving texts

If you started having problems sending or receiving texts, you may need to install an ESIM on your phone. I have an Iphone 13 and after installing a new IOS of some newer version and release, parts of my texting functions stopped working. I could not get texts sent to my phone such as a text for 2FA or a text from a non-Iphone user. My cell phone provider installed an ESIM on my Iphone 13 and all is good now.
