What's the point of Giffgaff today?
With o2 PAYG 3-2-1 tariff, 3p calls, 2p text, 1p per MB Data - o2 itself is cheaper than giffgaff today for credit based accounts.
In terms of bundles, there are better 30-day tariffs elsewhere where the data isn't second-tier "restricted' to o2. Giffgaff have an extremely iffy policy regards EU roaming, which really needs to be tested through the courts.
This sounds like - pretty much, the nail in the coffin, for anyone still using them.
