How calling cards work (and where they cost you)

Prepaid calling cards promise cheap international calls, but fees and expiry dates eat into the savings. Here is how they really work.

Updated June 2026

A prepaid international calling card gives you a balance and a low advertised per-minute rate to a destination. You dial a local access number, enter a PIN, then dial the international number. While they have been around for decades, the headline rate rarely tells the whole story.

The basic mechanics

Each card has a stored balance and a published rate per country. You call an access number, authenticate with a PIN, and your balance is drawn down per minute while you talk. The card provider routes your call over wholesale telephony to the destination.

Where the costs hide

  • Connection fees charged each time you place a call.
  • Daily or weekly maintenance fees that quietly drain the balance.
  • Rounding to the nearest few minutes instead of per-second billing.
  • Expiry dates that void any unused balance.
  • Higher rates from mobiles or payphones than advertised.

A clearer alternative

Browser calling shows the all-in per-minute rate before you connect, with no access numbers, PINs, connection fees, or expiry. With Localcall, you simply paste the number, see the price, and call; your credits are valid for 12 months from purchase.

Frequently asked questions

Most cards add connection and maintenance fees on top of the per-minute rate, and round call length up. Those charges drain the balance faster than the advertised rate suggests.
