Pro’s

  • Monthly rolling plan, great flexibility.
  • Competitive prices offering good value.

Con’s

  • No 5G coverage.
  • After the first 80GB, data speeds will be capped at 384Kbps between 8am and midnight.
 

Run by the O2 Network, giffgaff brings a different approach to pay monthly plans with ‘goodybags’. The bags offer great flexibility, but they don’t offer as great value as they once did and they aren’t the only flexible deals out there anymore. The network has a ‘goodybag’ called ‘Always-On-Data’ and it’s an unlimited data plan.

Always-On has 4G data speeds, but only for the first 80GB of usage. Past that point your download speeds will be capped at 384Kbps between 8am and midnight till you renew your ‘goodybag’. giffgaff will provide 5G coverage in the future, but at the moment customers can only get 3G/4G services.

There’s also no mention about any fair usage policy while using your SIM in the UK. As for roaming in the UK, you’re given about 15GB data per month. There’s no set in stone number so you’ll have to use Virgin’s EU fair usage calculator.
