ASDA Mobile Unlimited Data Plans
In the UK, ASDA Mobile offers low-cost SIM cards with 4G & 5G coverage from Vodafone.
At present, ASDA Mobile is offering unlimited data from £20 per month. You’ll get download speeds of up to 2Mbps on their £20 plan, download speeds of up to 10Mbps on their £22 plan, and download speeds of up to 150Mbps on their £24 plan:
Network | Minutes | Texts | Data | Monthly Cost |
---|---|---|---|---|
![]() | Unlimited | Unlimited | Unlimited 2Mbps max | £20.00 |
![]() | Unlimited | Unlimited | Unlimited 10Mbps max | £22.00 |
![]() | Unlimited | Unlimited | Unlimited 150Mbps max | £24.00 |
There’s no hidden fair usage limit that restricts how much data you can use (as long as it’s for your own personal non-commercial usage).
There’s no contract and no credit check required to join ASDA Mobile and you can sign up to the plan on a one-month rolling basis. This gives you flexibility to change your plan at any time (e.g. upgrading to an unlimited data plan with faster speeds or downgrading to a regular plan without an unlimited data allowance).
Download Speeds
Aside from the price you pay for your plan each month, the only difference between ASDA’s unlimited data plans is the maximum download speed you can get:
- The £20 unlimited data plan gives you download speeds of up to 2Mbps. This is enough for most day-to-day usage such as browsing the web, using messaging applications, listening to music and watching standard-definition video. However, you won’t be able to do things like streaming HD-quality video.
- The £22 unlimited data plan gives you speeds of up to 10Mbps. This will allow you to stream in HD and to make HD-quality video calls. You’ll also get a far better experience when downloading and sharing files from your phone.
- The £24 unlimited data plan gives you speeds of up to 150Mbps. This will allow you to do pretty much anything you’d like to do on your phone, including downloading large files and watching online video in 4K ultra-HD quality.
It’s important to remember that this is only the maximum possible download speed. In reality, the actual speeds you get may still be slower than this (e.g. due to network limitations or due to the coverage where you are).
Typically, if you’re using a plan without speed restrictions, Vodafone says you should be able to get download speeds of 23-35Mbps on their 4G network and download speeds of 150-200Mbps on their 5G network.
For this reason, ASDA’s speed-restricted plans tend to be a bit slower than on alternative networks. However, that might not cause too much of a problem if it’s already fast enough for what you actually want to do. For the best online experience, you should choose the £24 plan which has a 150Mbps speed limit.
Comparison to Alternatives
Unlimited Data With Vodafone Coverage
If you’re looking for an unlimited data plan that uses coverage from Vodafone, you can also consider one of the following options:
- Lebara Mobile offers unlimited data with 4G & 5G coverage from Vodafone. There are no speed restrictions on Lebara’s unlimited data plans.
- Vodafone offers unlimited data with 5G coverage. Like ASDA Mobile, you’ll need to choose between three different plans, each one with a different maximum speed. The Unlimited Lite plan gives you download speeds of up to 2Mbps, the Unlimited plan gives you download speeds of up to 10Mbps and the Unlimited Max plan gives you uncapped 4G & 5G speeds.
- VOXI offers unlimited data with 5G coverage from Vodafone. There are no speed restrictions on VOXI’s unlimited data plan and it’s available without a contract or credit check.

If you’re looking for unlimited data without a contract, you can also consider the one-month rolling plans from giffgaff, SMARTY, Superdrug Mobile and VOXI.
The following table shows a side-by-side comparison of these plans:
Network | Minutes | Texts | Data | Monthly Cost |

On giffgaff’s £25 Always-On data plan, you’ll get 4G speeds on the first 80GB of data each month. After this, your downloads will be restricted to a maximum speed of 384kbps (approximately 0.4Mbps) between 8am and midnight each day.

Other Unlimited Data Plans
If you’re willing to consider a wider range of networks, you can get unlimited data for as little as £16/month. For instance, Three offers a 5G unlimited data plan without any speed restrictions or hidden limits on usage.

Coverage
2G, 3G & 4G Coverage
On the new unlimited data plans from ASDA Mobile, you’ll now get your coverage from Vodafone instead of EE. This means you’ll get 99% population coverage from Vodafone’s 2G, 3G and 4G networks.
Before you sign up to an unlimited data plan on ASDA Mobile, it’s worth double-checking the coverage in your area. You can do this by entering your postcode on ASDA’s online coverage map:
Check ASDA Mobile Coverage (mobile.asda.com) →
Unfortunately, Wi-Fi Calling and 4G Calling are not currently available to ASDA Mobile customers.
5G Coverage
You’ll also get access to Vodafone’s 5G network in 100 UK towns & cities if you choose an unlimited data plan from ASDA Mobile. You’ll need a 5G-ready phone to use it.
If you choose the 2Mbps or 10Mbps unlimited data plans from ASDA Mobile, you’ll have access to Vodafone’s 5G network but you won’t be able to benefit from the faster speeds. Instead, the only benefits you’re able to utilise are the greater network capacity and the lower amounts of latency (this should make things more reliable and more responsive than on a 4G connection).
If you choose the 150Mbps unlimited data plan from ASDA Mobile, you’ll be able to get download speeds of up to 150Mbps on a 5G connection. This is about five times faster than a 4G connection. However, it’s not as fast as the uncapped 5G download speeds available on some other 5G SIM-only plans.
At present, ASDA Mobile offers 5G coverage in the following UK towns and cities:
Now Live | 100 towns and cities are live on ASDA Mobile 5G (May 2023) Aberdeen, Alexandria, Ambleside, Aughton, Basingstoke, Bebington, Belfast, Birkenhead, Birmingham, Bishopbriggs, Blaydon, Bolton, Bootle, Bournemouth, Bradford, Bristol, Cardiff, Cheadle, Cheltenham, Chesterfield, Clydebank, Crawley, Crosby, Dewsbury, Dinas Powys, Droylsden, Dudley, Dundee, Eccles, Edinburgh, Eston and South Bank, Felling, Gateshead, Glasgow, Gloucester, Gosforth, Guildford, Hebburn, Helensburgh, Horwich, Huddersfield, Hull, Huyton-with-Roby, Isle of Scilly, Jarrow, Killingworth, Kingswood, Lancaster, Leeds, Lisburn, Liverpool, Llandudno, London, Longbenton, Manchester, Mangotsfield, Middlesbrough, Morley, Mosborough, Newbury, Newcastle, Newtownabbey, North Shields, Oldbury, Paisley, Penarth, Pendlebury, Plymouth, Portsmouth, Prescot, Prestwich, Pudsey, Rawmarsh, Reading, Rochdale, Rotherham, Salford, Sheffield, Shipley, Solihull, South Shields, Southampton, Stockport, Stockton-on-Tees, Stoke-on-Trent, Stranraer, Stretford, Sunderland, Sutton Coldfield, Swansea, Swinton, Tynemouth, Urmston, Wallasey, Wallsend, Warrington, Washington, Whitley Bay, Wolverhampton, York |

Tethering & Personal Hotspot
Tethering or personal hotspot refers to the process of sharing your smartphone’s internet connection with another device (e.g. with your laptop or tablet). It’s often used as a convenient way to get access to mobile broadband on-the-go.
You can use tethering and personal hotspot on all of ASDA Mobile’s unlimited data plans. However, we wouldn’t recommend it on the slower plans like the 2Mbps unlimited data plan. This is because the 2Mbps speed limit will restrict what you’re able to do when you tether.
Keeping Your Phone Number
If you’re switching from another network to ASDA Mobile, it’s easy to keep your current number.
Start by ordering your unlimited data plan from the ASDA Mobile website. Once you’ve done that, you can request a PAC Code from your old network. You can get one through their website or app, or by texting PAC to 65075.
When your new unlimited data SIM card arrives in the post, submit your PAC Code online through the ASDA Mobile website. Alternatively, you can call ASDA Mobile’s customer support team on 2732 to give them the PAC Code on the phone. Once you’ve done this, your phone number transfer will normally take place on the next working day.
For a step-by-step guide on how to move your phone number to ASDA Mobile, please select your current mobile network from the drop down menu below:
There’s also further information in our full guide to transferring your phone number between networks.

Thank you in advance,

Hi Lucinda,
Thanks for your comment. You can simply choose the plan you’d like from this table. Once you’ve signed up, they’ll send you a SIM card through the post that you just need to put inside your mobile phone. Alternatively, if you already have an ASDA Mobile SIM card, you can just add the bundle you want to that SIM.
Hope this helps,
Ken
