Giffgaff 4G Coverage and Network Summary

15th March 2017

GiffGaff Network Coverage

Giffgaff is one of a number of MVNO’s entering the 4G market, but Giffgaff has certain advantages including a known name, a solid history as a 3G provider and low prices.

The network uses O2 for signal, so where O2 has 4G Giffgaff also has 4G. So right now it should have 4G coverage for over 78% of the UK population and that’s likely to reach 98% by the end of 2017.

Our Rating


Giffgaff’s 4G coverage relies on O2’s, which means it’s currently at around 78% population coverage. That puts it behind EE and Vodafone at 97% and 88% respectively, but ahead of Three. Giffgaff also has strong 3G and 2G coverage, so you should be able to get mobile data of some kind almost everywhere.

Network Type Coverage by population
4G  78%
3G 98%
2G 99%

Network Speeds and Frequencies

Giffgaff uses standard 4G, which is around 5 times faster than a typical 3G network. The network’s average 4G download speed is 18.48Mbit/sec, and its average 4G upload speed is 9.40Mbit/sec.

That’s not quite up there with the fastest UK networks, but it’s still very quick, and should allow for smooth streaming, downloading and web browsing on your phone.

  • Average Download Speed: 18.48 Mbit/sec
  • Average Upload Speed: 9.40 Mbit/sec

Giffgaff only uses the 800MHz band for 4G, but this band is ideal for delivering coverage across the UK. It’s long range, so it can travel a long way between masts, making it suited to, well, everywhere really, but most notably rural locations, as masts are often spread far part in the countryside. But it’s also good at passing through walls, making it great for towns and cities as well.

You can find in depth details of this band and others in our 4G frequencies guide.

  • 900MHz used for 2G/3G
  • 1800MHz used for 2G
  • 2100MHz used for 3G


Giffgaff has a range of Pay Monthly and SIM Only plans, along with the option to Pay As You Go. All plans come with 4G data at no extra cost. Plans are available from as little as £5 per month.

Pay Monthly Phone Plans





Max Data Allowance


Contract Length

24 Months

Giffgaff’s Pay Monthly plans are all 24 months long and come with up to 6GB of 4G data. There’s also an unlimited data plan (or ‘Always On’ as Giffgaff calls it) which lets you go beyond 6GB but caps your speeds at 256kbps once you exceed 6GB.

Tethering is also included on all plans – though with the ‘Always On’ plan you can only tether with the first 6GB.

SIM Only Plans





Max Data Allowance


Contract Length

1 Month

Giffgaff’s SIM Only plans give you exactly the same selection of tariffs as Pay Monthly – so you can get up to unlimited data, but only up to 6GB at 4G speeds, and only up to 6GB for tethering.

However, you’re only tied in for 1 month on SIM Only, and of course you’ll pay less, as you’re not paying for a phone as well.

Data Only Plans – For Tablets and Dongles

Giffgaff offers both 500MB and 1GB Data Only plans, so you can get your tablet or dongle online without paying for unneeded minutes and texts. These are each 1 month long and start at £5.

Pay As You Go

Giffgaff doesn’t offer any Pay As You Go bundles (though the SIM Only bundles should do that job, since they only last 30 days), but it does allow you to Pay As You Go, at rates of 15p per minute, 5p per text and 5p per megabyte of data. Calls and texts to other Giffgaff numbers are free.

Giffgaff Roaming Destinations

Giffgaff doesn’t currently offer any cheap or inclusive roaming for data, texts or calls.


Giffgaff stands out through low prices and flexible tariffs, with a range of SIM Only plans that you’re only tied into for a month.

It’s also one of those rare networks that has unlimited data on some tariffs – though speeds are throttled above 6GB, so it’s not as good for this as, say Three.

Tethering is allowed too, but there’s no inclusive roaming, all of which makes Giffgaff a strong network for light to middle-weight data users who don’t do a lot of travelling.
