  • Giffgaff sim lost! Got new sim but unable to request PAC via old sim as you require the old sim to text and request your PAC to keep the old number. Any way around this please?

  • Hi Ken,

    I am with giffgaff pay monthly all I want to do is transfer my number to a new phone I have purchased

    • Hi Ann,
      Many thanks for your comment. To be clear, I think you’re looking to stay on giffgaff but simply to change your handset for a newer model? If so, the easiest thing to do would probably be to just move your SIM card from one handset to another. If for some reason you aren’t able to do this (e.g. because you need a SIM card of a different size), you can order a new SIM card from giffgaff here. Once you have it, you can use the giffgaff SIM Swap service to move your service to the new SIM card.
      Hope this helps!
