|Data||Minutes & Texts||Price|
Priced at £6/month the 2GB data plan is quite wallet friendly and it’s one of the most affordable SIM Only plans on the UK’s mobile market.
Pay As You Go
Sky Mobile doesn’t have a PAYG mobile service, nor does it offer any monthly rolling plans. If you wish to join Sky Mobile you’ll have to undergo a credit check and sign a contract.
If you need a pay as you go service with O2’s network coverage, you might want to check out giffgaff’s goodybags. Make sure to read Half Cooked’s extensive giffgaff review before you make your final decision.
Pay Monthly Phones
Sky Mobile proposes a nice selection of phones from popular manufacturers like Apple, Samsung, Sony and Huawei. The network’s selection includes the latest flagship handsets which support 5G services like the Samsung Galaxy S10 and iPhone 11. You can also find cheaper entry-level devices and mid-range to high-end mobile phones.
Sky Mobile locks you in for a long time if you want to purchase a phone with your SIM deal. The carrier gives you two options in regards to contract length and how often you can upgrade your handset. You can read our Sky Mobile Swap Review for more information, the short version is explained right below.
Swap12 allows you to upgrade your device every 12 months, however your contract length will be 24 months.
Swap24 works the same way, as you can upgrade your phone every 24 months and your phone contract will be for 36 months. The latter offers a lower monthly price, however overall you’ll be locked in for a year longer.
You can have a look at Sky Mobile’s official store to see which handsets are available.
Network Coverage & Speeds
2G, 3G & 4G Coverage
Sky Mobile uses the O2 network to offer its customers identical coverage on 2G, 3G and 4G in the UK. The mobile virtual network provides over 99% population coverage alongside decent landmass coverage. Regardless, you should still use Sky’s coverage checker
However, looking at data speeds we see that O2 lags behind all the other networks. Opensignal’s April 2021 report shows that the carrier has an average download speed of 17.3Mbps and upload speeds are measured at 6.7Mbps. This makes O2, & therefore Sky Mobile the slowest network provider in the country in regards to 4G data speeds.
Top spot still belongs to EE with 39Mbps average download speeds and 9.1Mbps upload speeds. You might want to see how O2 compares to EE and we’ve got you covered. Make sure to have a look at Half Cooked’s EE vs O2 review.
Unlike most other MVNOs Sky Mobile offers 5G signals to its customers. At the moment Sky Mobile customers can get 5G services in 193 towns and cities, and this number will only increase over time.
Looking only at Opensignal’s April 2021 speed tests on a 5G connection, O2 has the second fastest average 5G download speeds in the UK at 129Mbps. O2 5G upload speeds are averaging around 10Mbps. Sky Mobile customers can enjoy the same level of super-fast internet experience O2 members do. Currently EE is the fastest 5G mobile network in the UK with over 140Mbps 5G internet speeds.
To benefit from Sky’s 5G coverage you must have a compatible handset. 5G is free for Sky VIP members, and if you’re not a VIP member you can easily become one using Sky’s main app at no extra cost. If you wish to use 5G without being a VIP member, you’ll have to pay an extra £5 monthly.
Voice Call Quality
As Sky Mobile is powered by O2, we must focus on O2’s call test results. When it comes to voice call quality, we rely on tests done by independent bodies like Open Signal and umlaut. Both are respected and widely accepted as authoritative and objective when it comes to testing.
O2 shows significant improvement over the last few years and the network’s customers enjoy better voice calls as a result. The network also jumped ahead of Three according to umlaut and it’s ranked in the third place with a score of ‘satisfactory’. However, it’s still behind EE and Vodafone.
Both Open Signal and umlaut say, the call setup times of O2 were considerably longer than those of EE and Vodafone, and on par with Three’s.
Wi-Fi Calling & 4G Calling
With WiFi Calling even if there’s no signal available, you can make & receive calls and send & receive texts like you regularly do. All you have to do is connect to an available Wi-Fi with a compatible handset.
And with 4G Calling (aka VoLTE) you can make and receive calls over a 4G network. Instead of using 2G/3G signals, your network will utilise 4G and your calls will connect quicker and they’ll be clearer.
More often than not mobile virtual networks will opt out of these two perks to offer more competitive prices. This is not the case for Sky Mobile though. The network offers both these awesome features at no extra cost and all price plans are included.
Don’t forget to make sure your device is compatible with these features.
With Sky WiFi, you can get free and unlimited Wi-Fi in thousands of popular places across the UK by connecting to hotspots when you’re out and about.
Some carriers like BT Mobile and Virgin Mobile offer free Wi-Fi hotspots all around the UK. Sky Mobile has thousands of free Wi-Fi hotspots too. The scheme is called Sky WiFi and it’s quite simple to use. With Sky WiFi you can get free and unlimited Wi-Fi in some of the most popular places across the UK. You’ll have to sign up and log in to the service once and from that moment on you’ll automatically connect wherever there’s a Sky WiFi hotspot.
Tethering is using the mobile signal from your device as a Wi-Fi connection to connect other Wi-Fi enabled devices to the internet such as other mobiles, tablets or computers. This is also known as using your handset as a personal hotspot.
On Sky Mobile you’re allowed to tether on all plans freely at no extra cost. You may even use the rolled over data in your Sky Piggybank. If you’re regularly tethering you should be extra careful, because tethering eats up data at a much faster rate. Given how Sky Mobile doesn’t offer large data allowances you should be extra careful.
You can roam freely with your Sky Mobile SIM in over 30 European destinations like at home. This scheme is a bit limited, especially compared to some other networks in the UK. If you’re willing to pay an extra £6, you can purchase the ‘Roaming Passport Plus’ add-on and access your UK data in 12 more destinations in a 24 hour period.
Roaming Passport Plus works in the USA, Canada, Australia, New Zealand, Turkey, Switzerland, Hong Kong, Thailand, Qatar, South Africa, Christmas Islands and Cocos Islands. This feature is one of the very few ways to get wallet-friendly roaming data in Turkey at the moment.
Sky Mobile isn’t one of the best networks for making international calls from the UK, but there are some special add-ons for this purpose too.
SKY Mobile Features
At Half Cooked we rate the ‘Roll’ feature very highly. Hands down it’s one of the best data rollover schemes in the UK. Regardless of your tariff the leftover data will transfer over to your Sky Piggybank at the end of each month. You can store unused data for up to three years and withdraw it any time you want or cash it in for Sky reward points. With the reward points you can get a discount when buying a new handset or a voucher for renting movies and TV shows on Sky.
Another great thing about this scheme is you can also share this data with other plans if you have multiple tariffs under one account. This makes Sky Mobile a great choice for family mobile plans.
If you own a Sky TV membership as well as an active Sky Mobile plan, you can watch Sky TV and other Sky apps without using any of your regular data. You’ll also get Sky Go Extra at no extra cost.
If you don’t have a Sky TV subscription you can still benefit from this feature, but only on the Sky apps that don’t require a subscription. You’ll need to have at least 50MB of data available in order to use Sky Mobile’s ‘Watch’ feature. The scheme also works when you’re tethering to other devices, just make sure you’re watching through a Sky app and not a web browser.
While Sky Mobile locks you in fo 12 months, the network offers some flexibility between tariffs. You can switch between any plan you want thanks to the network’s ‘Mix’ scheme. Plus unlike most other mobile networks, Sky won’t reset your leftover data when switching between plans. That data will be safely stored in your Sky Piggybank.
If you’re switching to a bigger data plan, your new data allowance kicks in immediately, however, if you wish to downgrade changes won’t apply till your next bill date.
Sky Mobile makes upgrading mobile devices as simple as possible. You can cash in your unused data from your Sky Piggybank and get money off a new handset.
‘Swap’ is another eye catching proposition from the carrier. When buying a handset from Sky Mobile you can choose either Swap12 or Swap24 payment plans.Swap12 will allow you to get an upgrade every year. However, you’ll be signing up for a 24 month contract on Sky Mobile. You’ll choose a new device to upgrade to and once you get your hands on it, you’ll send your old one back to Sky. The network will put the value of your old device towards what’s left to pay on your credit agreement.
Swap24 essentially works the same way but you’ll be given an option to upgrade every two years and the operator will lock you in for 36 months. Swap24 deals come cheaper on a monthly basis, but overall you’ll be paying more due to committing to the network for a year longer.
If you’re also an existing Sky Broadband customer you get even more perks and free services. You can read out detailed Sky Broadband Review to learn all you need to know and then some more about this service. You can even get more perks by purchasing the Sky Broadband Boost, but it’s not essential.
