I would call Walmart depends on your carrier.
Definitely a question for your carrier
All depens on the carier and the plan. And if is pre-paid or post-paid.
Your question needs to be more specific for the reasons already started above
Depends on which carrier. The straight talk SIM kit is about $60 but it includes the first month of service too.
It depends on the carrier you want, sim card kits or BYOD kits cam cost around 5-10$, but the plans are the expensive part.
