Will a factory reset remove service from my phone?

[Your_mom_6969]

I am using an LG L41C which is CDMA. I want to flash a rom but I'll have to reset my phone. Will I keep my service or will I have to renew my number or something?

Does your phone have a sim card? If so, phone number and carrier info will be on card and not affected by flash or factory reset.

I have a CDMA phone and found it does not affect the service. Thanks for the help though.
