How do I get my LG Optimus L9 connected to Straight Talk?

Kathy Williams November 8, 2014

I have a LG Optimus L9 D415 I’ve been trying to get connected to Straight Talk for two days. The phone says searching most of this time. The rest of the time it says No Service. When it searches to find a network and register, it comes back “Unable to connect to a network at this time. Please try again.” What’s going on? T-Mobile was the previous carrier.
