Will I lose my phone service if I factory reset my iPhone?

I've been having issues with my iPhone and I'm thinking about factory resetting it. But I'm concerned that it'll shut off my phone service. I have straighttalk carrier, so like, if I factory reset my phone, will it shut off my phone service when it turns back on from resetting?

No. The service is linked to the SIM, not the phone, so resetting the phone will not interrupt service.
