why is my internet connection so slow on my phone?

[Olivia]

I just got this phone like a week ago. It's a straight talk. I downloaded a couple things then out of no where the internet started being real slow, so I deleted a few of the apps and my internet is still slow!. And I was thinking of doing a factory reset or is there another way to fix my problem?
