Different phone number showing when texting

[PapaPanthers 0]

So I finally got my eset security system to activate premium, But after doing so I've texted a couple of people and they show me a 707 phone number, which is not my phone number so I'm confused how can I get my regular phone number to show again without disabling my ESET

Are you talking about ESET Internet Security or ESET Smart Security Premium for Windows given that you have posted in this forum? If so, what application do you use for calling?
