Giffgaff 4G Coverage and Network Review

9th July 2019

GiffGaff Network Coverage

Giffgaff is one of a number of MVNO’s with 4G capabilities, but Giffgaff has certain advantages including a known name, unlimited data plans, a solid history as a 3G provider and low prices.

These are all good things, and there’s plenty more to like about Giffgaff, so is this the network for you? Not necessarily, as there are also some downsides to Giffgaff, as you’ll see below in our full Giffgaff review.

We’ve covered every key aspect of the network, including coverage, available plans, roaming, tethering and more, so you can see exactly what Giffgaff offers and why you should (or shouldn’t) choose it.

Summary

Pros

Cons

Short-term contracts

Not quite the best 4G coverage

Unlimited data on some plans

4G data speeds capped at 40GB

Allows tethering

No inclusive roaming beyond Europe

Our Rating

Coverage

Giffgaff’s 4G coverage relies on O2’s, which means it’s currently at around 99% population coverage indoors. That puts it behind Three and EE and in line with Vodafone. Giffgaff also has strong 3G and 2G coverage, so you should be able to get mobile data of some kind almost everywhere.

In an OpenSignal report from April 2019, O2 was found to have average 4G download speeds of 15.8Mbps, average 4G upload speeds of 7.2Mbps, and an average latency (the time the network takes to respond to a request) of 39.2ms.

That’s the slowest download and upload speeds, but the second best latency of the tested networks, and while Giffgaff itself wasn’t tested its reliance on O2 means its results would probably be similar.

4G

Giffgaff uses the 800MHz, 1800MHz, 2100MHz and 2300MHz bands for 4G. The 800MHz band is 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.

The 2300MHz band is better for busy areas where lots of people are trying to connect at once. However, it’s shorter range and can’t pass through obstacles as well. The 1800MHz and 2100MHz bands are a middle ground.

Giffgaff may at some stage also get access to O2’s 3400MHz spectrum, which is ideally suited for 5G.

You can find in depth details of these bands and others in our 4G frequencies guide.

Planned improvements

Giffgaff is reliant on O2 for most improvements, and that’s no bad thing, as O2 is regularly improving its network.

Currently O2 seems primarily to be focused on preparing for 5G – a service which it’s set to launch later in 2019. There’s no word on if or when Giffgaff will offer a 5G service, but the more 5G infrastructure O2 has, the better Giffgaff’s can be if it does launch one.

Traffic management

Giffgaff’s traffic management policy (or traffic flow as the company calls it) shouldn’t affect most users at all.

Giffgaff simply notes that users who consistently use extreme amounts of data as part of the Always On plan may be contacted about their usage and ultimately banned from buying further Always On goodybags if they’re unable or unwilling to reduce their usage.

However, Giffgaff predicts that it will contact as few as 1% of customers about this, as it’s only those who use mammoth amounts of data during peak hours that are affecting the network.

Contract Length

6, 12, 18 or 24 Months 1 Month

Giffgaff’s Pay Monthly plans come in a choice of 6, 12, 18 or 24 months and come with up to 40GB of 4G data. There’s also an unlimited data plan (or ‘Always On’ as Giffgaff calls it) which lets you go beyond 40GB but caps your speeds at 384kbps from 8am to midnight once you exceed 40GB.

Tethering is also included on all plans – though with the ‘Always On’ plan you can only tether with the first 40GB.

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 40GB at 4G speeds during peak hours, and only up to 40GB 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.

Giffgaff’s advantages include low prices and flexible contract lengths, as well as cheap international calls to some destinations, but data limits are quite low compared to some networks – other than ‘Always On’, which is still restrictive thanks to its speeds. Having said that, for most users 40GB will be plenty.

Data Only Plans – For Tablets and Dongles

Giffgaff doesn’t currently offer any Data Only plans.

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.

Tethering

Giffgaff allows tethering and you can use as much of your data as you want for this. The only exception is the Always On plan, which limits you to 40GB of monthly tethering data.

WiFi Calling

Wi-Fi Calling means making calls over Wi-Fi, rather than your mobile network. This is ideal if for example you have signal blackspots at your home or office, as you can use your Wi-Fi network to stay in touch. It’s a seamless experience too, with no separate apps or accounts, however, Giffgaff doesn’t currently offer this service.

VoLTE

VoLTE stands for Voice over LTE, though it’s sometimes called 4G Calling. It means making calls over 4G, whereas typically you need a 2G or 3G signal. The main advantage of this is it essentially means you have coverage in more places, as there will be areas with 4G but no other signal type. However, Giffgaff doesn’t currently offer VoLTE.

Roaming Destinations

Giffgaff lets you use your minutes, texts and data at no extra cost in 37 destinations, namely:

Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, French Guiana, Germany, Gibraltar, Greece, Guadeloupe, Hungary, Iceland, Ireland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Martinique, Mayotte, Netherlands, Norway, Poland, Portugal, Reunion, Romania, San Marino, Slovakia, Slovenia, Spain and Sweden.

As with most networks it's limited to European ones however, so if you want to travel more globally Giffgaff may not be the network for you. Also, if you have 'Always On' data or the £20 goodybag (which comes with 40GB of data) you can only use up to 20GB of it for roaming.

Customer service

One of the few remotely recent reports on Giffgaff’s customer service is the Which? H1 2017 UK Mobile Network Survey, and it’s very promising, as it ranks Giffgaff top.

The survey asked 4,026 members of the public for their opinions, and Giffgaff was given an overall customer score of 81%, as well as a customer service score of 4/5 (no networks got 5/5), an ease/speed of contacting score of 3/5, a value for money score of 5/5 and an incentives score of 3/5.

The network also has a 7.9/10 rating on Trustpilot at the time of writing, a rating which is considered ‘Great’.

Conclusion

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 40GB, so it’s not as good for this as, say, Three.

Tethering is allowed too, but there’s no inclusive roaming beyond Europe, all of which makes Giffgaff a strong network for light to middle-weight data users who don’t do a lot of travelling. Everyone else might be better off looking elsewhere.
