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 | Data | Monthly Cost | |
|---|---|---|---|
| Unlimited data 2Mbps max speed | £20.00 per month No contract | See deal |
| Unlimited data 10Mbps max speed | £22.00 per month No contract | See deal |
| Unlimited data 150Mbps max speed | £24.00 per month No contract | See deal |
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.

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 4G networks. In addition, you’ll have access to Vodafone’s 5G network in areas with coverage.
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:

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:

Wanted to let you know the reality of ASDA’s so called ‘unlimited’ service. In a nutshell, it is NOT unlimited.
Our £24 unlimited bundle was automatically shut down without notice yesterday. Even worse, ASDA emptied the balance on the account charging for data at their per 1MB tariff. 😦
Note upon calling ASDA customer service they did reinstall our balance. Also experience with ASDA mobile customer service is very good; far superior to other businesses.
They claim the (and all providers) are REQUIRED by OFCOM to not allow more than 1TB of data use for any data plan per month. Initial searching has returned no law or OFCOM regulation of this type.
If anyone knows of the existence of any such law or regulation in the UK capping mobile data per month to 1TB please advise with a URL or other reference.
Very helpful site here BTW. 🙂 Thanks!

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
