Will I lose my phone number and plan if I factory data reset my phone?

I want to factory data reset my phone. It feels nice to have a phone without so many things on it and I like the less amount of storage I have on it. Needless to say, I want to reset it. My phone is an HMD Vibe, and I just want to make sure I won't lose my plan, or my number. My Google account has all my contacts attached to it so I don't have to worry about that, it's just that I'm worried about losing my plan and stuff.
