I bought my straight talk simple card from Walmart in tunersville if I take it back to be put in my phone will they charge me a few to Install it?

Doubt they will help.

The Straight Talk Card & Activation is a Kit that is an all one price when purchased from, Walmart. It comes with Home follow instructions to get started. Taking the kit back to Walmart will be the same as another person reading the instructions and following the steps, With no extra installation fee. If you don't feel comfortable doing it yourself, Someone in the electronics Department should be able to help.😊
