Networks offering unlimited data

EE

Overview

Pros	Cons
Great coverage and speeds	Premium prices
5G included and no speed restrictions	Lengthy contract durations
Data sharing and Smart Benefits

EE offers unlimited data plans on SIM Only and with Pay Monthly phones.

Currently they offer three unlimited data SIM plans, two of which are on 24-month contracts and one of which is on a 12-month plan. They come with 5G data, and unlimited minutes and texts, with the main difference between them being whether you get zero, 1 or 3 Smart Benefits included, with the 12-month plan not including any.

Smart Benefits currently available to choose from on the 24-month plan that comes with 1 benefit are Apple Music, Netflix, BT Sport Ultimate, and a Roam Abroad Pass (which lets you roam for free outside Europe, and removes the £2 daily European roaming charge once EE adds it in 2022).

The plan with 3 benefits (designed primarily for iPhone customers) has the options of Apple TV Plus and Apple Arcade in place of Netflix.

	24 Month Plan Includes 5G data + 3 Smart Benefits	£41 a month View Deal
	12 Month Plan Includes 5G data	£37 a month View Deal
Plans include roaming in Europe and unlimited tethering

Those who have multiple plans on their account can also gift up to 100GB of data per month to another EE plan (or 120GB if you have a 5G Smart handset plan), which is good for those with children who run out of data.

There is a small premium to pay for choosing EE, but the network offers higher average speeds and has more widespread coverage than its rivals. There are some slight fair usage terms though, which you can see in the chart at the end of this article.

Data roaming also comes at no extra cost on all plans until May 23rd, 2022, and covers 71 worldwide destinations in Europe and beyond. Free data roaming on Three is limited to 12GB though, above which you’ll be charged £3 per gigabyte.

Plus, free roaming is being removed on May 23rd, 2022 – though customers who signed up for a plan or upgraded before October 1st, 2021, will keep this perk for the duration of their contract.

Beyond these roaming restrictions there is currently no fair usage policy for unlimited data on Three. The network used to mention a 1000GB monthly soft cap (which is still far more than most people would ever use), but reference to this has been removed.

Asda Mobile

Overview

Pros	Cons
Flexible Pay As You Go plans	Speed restrictions on all plans
Uses Vodafone network
5G included

Asda Mobile launched unlimited data plans later than most, but they’re available now, alongside 5G speeds using Vodafone’s infrastructure.

At the time of writing the network sells three different unlimited data 30-day SIM Only plans, and while they all let you use 5G signals, only the one listed at ‘150Mbps’ will offer 5G speeds – the other two options are slower, and even the top option is presumably capped, since 5G is capable of higher speeds than 150Mbps.

Asda Mobile also allows tethering and free roaming in much of Europe, but there aren’t any handset plans – you can only go SIM Only or pay as you go.

Giffgaff

Overview

Pros	Cons
Uses O2 network	Speed restrictions after 80GB usage on 4G plan
5G plans available
Flexible Pay As You Go plans

Giffgaff, which use O2's network, offers an unlimited data goodybag (add-on) with 4G data, or a golden goodybag (add-on) with unlimited 5G data included. They can both be purchased on SIM Only or with a mobile phone.

There are some restrictions with the 4G plan, with only the first 80GB of use per month being at full 4G speeds. After that, speeds are capped at 384kbps between 8am and midnight, which is quite slow. You can tether, but the same speed restrictions apply.

The 5G plan has no such speed restrictions, but there is a fair usage policy stating that you should use under 650GB of data a month, and shouldn’t tether with 12 or more devices at once.

Giffgaff Pay As You Go plans
Unlimited data Unlimited minutes Unlimited texts	4G Plan * speeds restricted after 80GB use	£25 a month View Deal
	5G Plan	£35 a month View Deal

Free roaming meanwhile is fully capped at 20GB per month on both plans and the only way to use your data beyond Europe is to pay for the roaming data separately.

Tesco Mobile

Overview

Pros	Cons
Uses O2 network	Long contract durations
5G plans available with no speed restrictions	Prices not significantly lower than O2

Tesco Mobile, which uses O2's network, offers unlimited data on both SIM Only and Pay Monthly, and on both 4G and 5G plans (but at the time of writing 5G doesn’t come as standard, so make sure you’re on a 5G plan if you want it).

Note also that at the time of writing, reference to 5G SIM Only plans doesn’t seem to be included on Tesco’s site, so if that’s still true when you look then check with the network before buying if 5G is important.

The plans are available in 12 or 24-month varieties on SIM Only, or variable lengths with a handset. You can also roam for free in Europe and tether.

Pros	Cons

However, unlimited data is not available on mobile broadband plans. There are also restrictions when roaming. This cap changes though, so for an up to date figure, use Virgin Mobile’s fair use calculator.

Pros	Cons
