  • Ok I bought a second hand iPhone 6 to use with my existing Giffgaff sim. It kept dropping 4g signal down to E or GPRS. I thought the sim was to blame so ordered a replacement from Giffgaff, but it's still doing the same thing. I've done a hard reset, reset network settings, changed carrier settings to another network that doesn't run Giffgaff (runs on o2) and back to automatic and it still drops 4g after a few minutes.

    I tried my girlfriend's vodafone sim and it seems to work fine so I'm pretty sure it's not the phone.

    I've left a support ticket with Giffgaff but in the meantime does anyone have any ideas?

  • Doesn't Giffgaff run on another companies network? I wonder if the other carrier is prioritising their own customers?
    I had a similar problem whilst on holiday and roaming which I solved by locking it to the one carrier who consistently gave me 3/4g but I don't think that helps here!

  • Yeah giffgaff runs on o2. I should have mentioned before that I bought the new phone because I broke my old one. The old one had a full signal all the time so it's not a problem with my location. I've tried locking to o2 but it still drops.
