A prepaid SIM card lets you pay first, use later.

You buy these things first:

  • load credits
  • phone balance
  • data packs
  • call deals
  • text deals

Then your phone company takes money from your balance. Each call costs a bit. Each text too.

When you hit zero, everything stops. Time to add more money!

This isn’t like postpaid plans. Those send you a bill after you use stuff.

How Does a Prepaid SIM Card Work?

It’s really simple, actually.

Here’s what you do:

  • buy the SIM card
  • put it in your phone
  • turn it on
  • add some money
  • pick a promo if you want
  • start calling and texting!

Your phone company takes money right from your balance.

Like this:

  • using the net eats up data
  • calls use up call money
  • texts take from SMS funds

Money gone? Just add more!
