As the £35 plan is a golden goodybag, you’ll need to switch on the “recurring goodybag” feature inside your giffgaff account. This means your plan will automatically renew every month until you cancel the renewal.
The £25 plan is a regular goodybag so you can buy it automatically if you wish. Alternatively, there’s the option of buying it manually from a top-up voucher or from your Pay As You Go credit.
Fair Usage Policy
Within their fair usage policy, giffgaff says their mobile service should only be used for “private, personal, and non-commercial purposes”. In addition, the following fair usage policy also applies for usage in the UK:
- On the £25 goodybag with Always On data, there’s a 384kbps speed restriction once you’ve used 80GB of data in one month. This speed restriction applies between 8am and midnight each day and can make it difficult to stream things like online video.
- On the £35 goodybag with unlimited 5G data, giffgaff says they’ll continuously monitor the amount of data you’re using. They say you should “avoid regularly tethering to 12 or more devices or regularly using unreasonably large amounts of data, including but not limited using around 650GB of data twice within a 6-month period”.
If you’re using your giffgaff SIM card abroad in a European country, you’ll be subject to a 20GB per month fair usage limit for roaming. Further usage beyond the 20GB limit will be charged at 0.36p/MB for the remainder of your goodybag, You should also avoid using your SIM card in Europe for more than 63 days in any four month period.
On the £25 goodybag with Always-On data, you’ll have access to uncapped 4G speeds for the first 80GB per month. In theory, it’s possible to get peak download speeds of up to 300Mbps but actual download speeds will normally be closer to 25Mbps.
If you use more than 80GB of data in one month, your maximum download speeds will be restricted to 384kbps between 8am and midnight each day. This maximum download speed is roughly equivalent to 0.4Mbps, or the approximate speed of a basic 3G connection. It’s enough for browsing the web, using social media and instant messaging applications. However, things like streaming video from the internet are unlikely to work smoothly at this speed. If you want to restore full-speed 4G data, you can choose to renew your £25 goodybag early.
If you have the £35 goodybag with unlimited data, you’ll have access to uncapped 5G download speeds. This is subject to you having a 5G-ready device as well as 5G coverage which is currently available in 193 UK towns & cities. The maximum download speed on 5G can be as high as 1,000Mbps (1Gbps) but average speeds of 150Mbps will be much more common.
In certain areas where the mobile network is congested, giffgaff also operates a traffic management policy called Traffic Flow. This applies to approximately 2.5% of their network and impacts around 0.15% of giffgaff members with the heaviest data usage on their network. If giffgaff believes you are “using more than your fair share of network resource”, they can apply an “upper speed restriction of 100kbps for a period of 30 minutes”.
Comparison to Alternatives
Besides giffgaff, there are also many other networks offering unlimited data in the UK. As long as you’re happy to sign up for a contract, you can get unlimited data for as little as £15/month elsewhere (e.g. on Three’s unlimited data plan which also includes 5G).
If you’re looking for unlimited data without a contract, this is also available on the unlimited data plans from Lebara Mobile, SMARTY, Superdrug Mobile and VOXI. For instance, SMARTY currently offers unlimited data for £15/month with uncapped 4G download speeds on the Three network.

Tethering & Personal Hotspot
Tethering or personal hotspot refers to the process of sharing your smartphone’s internet connection with another device (e.g. with your laptop or tablet).
On both of giffgaff’s unlimited data goodybags, you can use tethering and personal hotspot to share your data with other devices. However, giffgaff says you shouldn’t tether to more than 12 devices if you’re using the £35 golden goodybag with unlimited data.
On giffgaff’s £25 goodybag with Always On data, your download speeds will be restricted to a maximum of 384kbps if you’ve already used more than 80GB of data in the current month. This applies from 8am to midnight each day. Whilst you’re still able to use tethering and personal hotspot, the speed may not allow you to do very much on other devices.
If you’re travelling abroad, you can use your giffgaff goodybag allowances in 37 European destinations at no extra cost.
On both of giffgaff’s unlimited data goodybags, a fair usage policy of 20GB per month applies in Europe. If you exceed the 20GB limit, you’ll be surcharged at a rate of 0.36p/MB (equivalent to £3.60 per gigabyte). This is charged against your Pay As You Go credit on giffgaff.
If you’re travelling outside Europe, you won’t be able to use your giffgaff goodybag allowances. Instead, you’ll pay giffgaff’s international roaming rates which range from 20p to £5 per megabyte (equivalent to £200 to £5,000 per gigabyte). For this reason, it might be cheaper to use a different mobile network when you travel outside Europe.
