Different carriers cause more or less interference with GPS?

Unfortunately my GPS data from my last track day at Auto Club Speedway was extremely poor to unusable. I’m wondering if maybe the GPS system got more interference from the cellular antenna because I switched SIM cards from t-mobile to freedom pop.
Do different carriers use bands that may be closer to the GPS or perhaps this carrier has a weaker signal and the antenna is working harder which causes the interference?
My cellular antenna is about 3 feet from my GPS antenna as recommended. But I can see a signal quality of 3 "strong" with the cellular turned off and then won't go above 2 "acceptable" with it on.
I didn't have any issues with the GPS signal at the same track back in July when I was using a t-mobile card. It recorded a quality of 3 the whole day.
Also, regarding the note in the GPS section about turning on your device for 15 to 30 minutes before a race, does this mean the device will have to be on for this amount of time before any driving session? Will it lose whatever information it gathers if it is turned off during the day between sessions?
