Compare Sky Mobile Deals & Offers

Sky Mobile deals

Sky, a company known primarily for its brilliant subscription TV service, and then perhaps its broadband, began dipping its toe into the mobile market in 2017, offering SIM-only deals to Sky customers primarily. Sky Mobile does not operate its own network, but rather, much like other providers that aren't network owners, piggybacks on one of the main networks – in this case O2.

Since 2017, Sky Mobile has blossomed into a fully fledged provider, offering contract handset, SIM-only, and contract tablet and laptop deals. You don't have to be an existing Sky customer to take advantage of these deals anymore – anyone can get one. Let's take a look in a bit more depth.

Why choose Sky Mobile?

Sky Mobile has named its defining selling points with a series of not entirely clear single-word 'brands': Roll, Watch, Swap, and Mix. Rather than sending you digging through Sky Mobile's website to find out what these mean, we've boiled them down into a series of features that we feel are much easier to understand.

This is what you'll get with a Sky Mobile deal.

Data rollover – In essence, data you don't use can be rolled over to the following month in 1GB chunks. It is stored in a data 'piggybank' for up to three years. Theoretically, this means that if you accrue a decent amount of excess data you can reduce your monthly tariff using Sky's 'Mix' feature, which allows you to adjust your allowances every 30 days. You can also use your saved “piggybank” data to get money off a new phone.
Remix your minutes, data and texts – 'Mix' as Sky Mobile puts it, describes the ability to alter your usage allowances from one month to the next. It sounds like a lot of faff if you ask us, but beyond the above mentioned data tweaks, you might have a good use for it we haven't thought of yet.
Upgrade every 12 months – Sky calls this 'Swap'. When you sign up you choose either Swap12 or Swap24. With Swap24 you will have paid for your handset by the end of the contract and are free to upgrade to a new one as normal. With Swap12, though, you can upgrade every year. Sky will buy your old handset from you and credit whatever it's worth to the hire-purchase loan on your next phone – your monthly repayments will then be worked out accordingly on your new contract. You can actually swap to a new device at any time after the first month of your contract, but the value of the device you are swapping will need to cover the cost of the rest of your contract. If it is worth less, you will have to pay the difference.
Unlimited Sky Go streaming – Provided you are a Sky TV customer, you can stream Sky TV using the Sky Go app without using any of your data allowance

What does Sky Mobile offer?

Sky Mobile offers contract phones from a small-ish selection of popular manufacturers – it has the main bases covered, basically. On top of that it offers a (also small) range of SIM only deals with bonus data for Sky TV and broadband customers.

Sky pay monthly phone deals – Sky offers a wide range of handsets, both new and refurbished, from a small group of manufacturers: Samsung, Apple and Google, along with a small cadre of budget providers – Doro, Fairphone and Nokia. All handsets are available on either Swap12 or Swap24 terms (see above for definition). All Sky Mobile handsets are contracted – it won't sell you one outright
Sky SIM only deals – Sky Mobile only offers a handful of SIM-only deals. You won't find any unlimited mobile data allowances on Sky, though. The largest allowance is 100GB, which is quite a lot, but if you eat a lot of data each month, you might want to look elsewhere
Pay-as-you-go SIMs – Sky Mobile does not offer any PAYG SIMs at the time of writing
Data-only SIMs – Sky Mobile does not offer any data-only SIMs at the time of writing. However, it does offer some contract tablets, where the data-only SIM comes as part of the deal
Contract tablets – Sky Mobile offers a good selection of contract tablets from Apple and Samsung, as well as some contract laptops

How good is Sky Mobile’s network?

Despite a very long list of UK mobile providers, there are actually only four network providers. Network providers are companies who do everything other providers do, but also own and maintain their own physical UK mobile network. They are: Three mobile, O2 mobile, EE mobile and Vodafone mobile. As for everyone else, they piggyback (lease space) on one of these four networks.

Sky Mobile is on the O2 network. As such, the data speeds and network coverage match O2's own. According to a 2023 report by Opensignal, the O2 5G network is actually the slowest of the four when it comes to download speeds, offering average real-world download speeds of 23.5 Mbps. Vodafone fares better with an average of 34.6 Mbps, Three better still at 49.9 Mbps, and EE is the clear winner with average download speeds of 56.3 Mbps.

Roaming on Sky Mobile

Now the UK has left the EU, mobile contracts don’t automatically include roaming in Europe. However there are a number of primarily European countries where you can still use your call, data and text allowances as you would at home at an extra £2 per day for the privilege. There are 55 countries total, while other countries will be charged at individual roaming rates. Here are the 55 included in the roaming passport and passport plus:

Aruba (Netherlands Antilles), Australia (including Cocos Islands, Christmas Islands), Austria, Azores, Belgium, Bonaire (Netherlands Antilles), Bulgaria, Canada, Canary Islands, Croatia, Curacao (Netherlands Antilles), Cyprus (excl. Northern Cyprus), Czech Republic, Denmark, Estonia, Finland, France, French Guiana (French West Indies), Germany, Gibraltar, Greece, Guadeloupe (French West Indies), Hungary, Iceland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Madeira, Malta, Martinique (French West Indies), Mayotte (French Territories in the Indian Ocean), Netherlands, New Zealand, Norway, Poland, Portugal, Reunion (French Territories in the Indian Ocean), Romania, Saba (Netherlands Antilles), Sint Eustatius (Netherlands Antilles), Sint Maarten (Netherlands Antilles), Slovakia, Slovenia, South Africa, Spain, St Barthelemy (French West Indies), St Martin (French West Indies), Sweden, Switzerland, Turkey (incl. Northern Cyprus), UAE, and the USA.

For other destinations, you will need to check what the situation is before departing. Sky Mobile will also allow you to add a roaming spend cap, meaning you will not be able to accidentally spend over a set amount.

Frequently asked questions

What network does Sky Mobile use?

Sky Mobile is on the O2 network, meaning its data speeds and coverage/signal availability will match exactly with O2's. If you want to check whether you are likely to get a good signal where you live and/or work, you can use O2's signal map, found on its website.

Do I need to be a Sky customer to get Sky Mobile?

No. Sky Mobile operates completely independently of Sky TV and Sky Broadband.

Is Sky Go free with Sky Mobile?

Sky Go is free if you are a Sky TV customer. You cannot access Sky Go unless you have a Sky TV subscription. However, if you do have one, watching content on your mobile with Sky Go won't use up any of your data allowance.

Why do Sky Mobile Piggyback?

Because it doesn't own its own physical network. A network consists of masts as well as the underlying fibre cables that connect it all. Most providers piggyback onto one of the four UK networks. Sky piggybacks on O2.

Does Sky Mobile have wifi calling?

Yes, it does. Although it is not available on every single device that Sky Mobile offers. Broadly the better the phone, the more likely you'll be able to use wifi calling, but you may wish to check with Sky Mobile before making your purchase if it's something that concerns you.
