ASDA Mobile offers 5G-ready unlimited data plans with a choice of three speeds: up to 2Mbps, up to 10Mbps and up to 150Mbps.

In the UK, ASDA Mobile now offers a choice of three unlimited data plans from £20 per month. Using Vodafone’s 4G & 5G network for coverage, you can choose between a maximum download speed of 2Mbps, 10Mbps and 150Mbps. All of the ASDA Mobile plans are available on a one-month rolling basis with no contract or credit check required.

In this article, we’ll review ASDA Mobile’s unlimited data plans. We’ll start by comparing the three different plans and the maximum download speeds available on each one. We’ll then compare ASDA’s unlimited data plans to what is available on other networks before looking at the coverage available and how to keep your current number.

ASDA Mobile Unlimited Data Plans

In the UK, ASDA Mobile offers low-cost SIM cards that you can put inside your mobile phone for calling, texting and browsing.

With their recent move to using Vodafone’s network for coverage, ASDA Mobile has launched three new unlimited data plans. All of the plans include unlimited UK minutes, unlimited UK texts and unlimited UK data, but with a choice of three different maximum download speeds:

2Mbps max
£20.00
ASDA MobileUnlimitedUnlimitedUnlimited
10Mbps max
£25.00
ASDA MobileUnlimitedUnlimitedUnlimited

£30.00

You can get a maximum download speed of 2Mbps on the £20 unlimited data plan, 10Mbps on the £25 unlimited data plan and 150Mbps on the £30 unlimited data plan. Besides that, 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 £25 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 £30 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 £30 plan which has a 150Mbps speed limit.

For comparison, Virgin Mobile currently offers a 5G unlimited data plan for £25 per month with 5G coverage from Vodafone and no download speed restrictions. According to Virgin, you’ll get an average download speed of 177Mbps on their 5G network (faster than the maximum possible speed on ASDA Mobile’s service).

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 coverage from Vodafone. There are no speed restrictions on Lebara’s unlimited data plans and they say the average download speed is more than 20Mbps on their network.
  • Virgin Mobile offers unlimited data with 5G coverage from Vodafone. There are no speed limits on this plan and the average download speed is 177Mbps on 5G (or 37Mbps on 4G).
  • 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.

Unlimited Data With No Contract

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:

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 £20 or £25 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 £30 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 Live100 towns and cities are live on ASDA Mobile 5G (June 2021)

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 £20 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:

    Two of them are slightly disconnected what can this do maybe to get service on them???

    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
