What is the cost of a sim card?

The cost of a SIM card in the U.S. can be tricky because it varies so much. You’ll find the physical card itself costs anywhere from free to about $10. Many online carriers, like Mint Mobile or Visible, often send them out for free when you sign up for a plan. The big players like Verizon or AT&T might charge you that $10 fee, especially if you get it in a physical store.

Don't forget about eSIMs, too. Most newer phones support these digital SIMs, which are almost always free and can be activated instantly. The key thing to remember is the real cost isn't the tiny piece of plastic. It’s the monthly service plan you have to buy to make it work.
