$50 for the plan, $9.99 for each line, $10 for the texting plan(per line)and $30 for 2gb data plan. thats not share everything.
For instance iphone would be $50, plus $50 for the plan and then $9.99 for lets just say one basic phone without data plan or text plan. Monthly cost would be $110. You could then add 3 more lines.
