2026. 4. 7.읽는 데 약 5분

In today's globalised world, many people need a foreign SIM card, and giffgaff's flexibility and low-cost rules for keeping a number have made it the first choice of many international users. This article explains in detail how to keep a giffgaff number for the long term, and shares some key tips so that you can enjoy the convenience of a foreign number with ease.

How keeping a giffgaff number works

Before choosing giffgaff, it is important to understand how a number is kept. giffgaff requires a change in your credit balance every 180 days so that the number is not taken back. The change can come from any of these:

  • Sending a text: send one text within China or internationally, at about £0.30 each.
  • Using mobile data: simply going online meets the condition.
  • Making a call: make or receive an ordinary call; calls to emergency services or the official support line do not count.
  • Topping up: every top-up extends the period.

With these simple actions you can keep your giffgaff number valid for the long term.
