ASDA Mobile Review 2021: Save Money With Cheap Pay As You Go or Competitive 30-Day Bundles

ASDA Mobile offers one of the best pay as you go deals and it’s powered by EE, meaning they offer the best and fastest 4G coverage in the UK.


Latest Offer: 10GB of 5G data for just £10 a month!

ASDA Mobile’s 10GB data plan comes with unlimited UK calls and texts. Plus you get 5G at no extra cost.

ASDA Mobile also offers competitive prices and you don’t even need to sign a contract or pass a credit check to join their network.

There are many low-cost mobile virtual network operators in the UK and ASDA Mobile is one of them. Their traditional pay as you go deal is certainly outstanding and the carrier also offers some 30-day rolling bundles with competitive rates.

As is clear in the name, owned and operated by the supermarket brand ASDA, ASDA Mobile is using the Vodafone network as of April 2021. ASDA Mobile used to be powered by EE prior to this date.

ASDA Mobile charges 4/p minute, 4/p, text and 4p/MB. The MVNO now offers three different unlimited data plans.


  • One of the best all around PAYG deals in the UK.
  • 5G coverage powered by Vodafone.
  • Super competitive PAYG rates.
  • No contracts.


  • No vall quality improving features.
  • No data rollover or other perks.

Plans & Pricing

ASDA Mobile’s 30-Day Bundles offer better value for your money than their pay as you go deals. We’d recommend opting for a 30-day rolling bundle if you regularly use your phone. Having said that, while we find ASDA Mobile’s bundles competitively priced we think other options are worth exploring too.

The carrier is offering unlimited calls and texts on all their bundles after switching to Vodafone. This is a major improvement for the network, but on the other hand pretty much all the other UK networks are already offering unlimited calls and texts on all their plans. Unfortunately, ASDA Mobile doesn’t offer a data rollover feature.

If you’re looking for larger data allowances, you can also have a look at SMARTY’s and VOXI’s SIM only offers. You can also read our SMARTY Review and VOXI Review, or check out our SMARTY vs VOXI comparison if you wish to see which network comes out on top.

All ASDA Mobile plans come with unlimited texts.

Pay As You Go

This is where ASDA Mobile shines, as they offer some of the best PAYG rates in the country. If you don’t use your mobile device that often and don’t want to bother topping up every month, then ASDA Mobile’s pay as you go deal is probably the right choice for you.

The carrier will charge you for what you use on a traditional pay as you go basis. You’ll be charged at 4p/minute, 4p/text and 4p/MB.

You need to make a chargeable activity at least once every 180 days to keep your SIM active, so even a simple short phone call or data event will keep your SIM active. If 180 days pass since your last chargeable activity, your account will be suspended but you’ll still be able to receive calls and hold onto your credit.

Your credit won’t expire as long as your account is active, but if 270 days pass since your last chargeable activity, your credit will be removed. The network will also suspend your account completely, but you’ll still keep your phone number for another 90 days. If your account stays inactive for longer than 360 days the carrier will delete your phone number.

Another great PAYG option is 1p Mobile, which runs on EE’s network. Check out our 1p Mobile Review to learn more.

Pay Monthly Phones

There are no pay monthly phone deals or pay as you go phone deals on ASDA Mobile.

If you’re looking for a new handset with a desirable tariff, we’d suggest checking out O2. The network even splits your airtime bill and phone bill into two, providing you the flexibility to upgrade your device whenever you wish. See our extensive O2 Review and discover everything you need to know about the network.

Network Coverage & Speeds

As mentioned above, ASDA Mobile switched to Vodafone as of April 2021. They no longer get their coverage from EE, this means they’re no longer offering the best 4G network coverage in the UK. The network also uses 3G and 2G; the latter is used mainly for regular voice calls and also as a fall back option.

In the UK, Vodafone and therefore ASDA Mobile offer 99% population and over 90% landmass coverage. The host network aims to cover more ground by the end of 2021.

Opensignal’s April 2021 speed test results state that Vodafone customers get an average of 21Mbps 4G download speed, accompanied with 8.1Mbps upload speed. Read our EE Review to discover why the network has the best coverage and fastest speeds.

5G Coverage

When we examine Opensignal’s April 2021 speed test results on 5G connections, we can see that ASDA Mobile offers the slowest 5G download speeds in the UK, averaging around 103Mbps. Their best unlimited data plan also has a speed restriction of 150Mbps. ASDA Mobile 5G is live in 100 cities and towns at the time of writing, and it increases on a steady basis.

You’ll need a 5G ready handset and and an ASDA Mobile 5G plan in order to get superfast download speeds from the network. Thankfully, besides the 1GB and 3GB data plans, all ASDA Mobile tariffs come with 5G coverage.

We’d also recommend checking out both Three and Tesco Mobile for a PAYG 5G deal. You can read our Three Review and Tesco Mobile 5G Review to learn more about what each network offers. OOKLA’s test results refer to Three as the fastest 5G mobile network with download speeds at 201Mbps, but we find Opensignal’s test results more reliable and healthy.

Voice Call Qualit

We put our trust in independent & objective testing bodies like umlaut, Open Signal and OOKLA for this category, because personal experiences can differ vastly. These companies perform nationwide voice call tests and they proved themselves to be reliable sources.

Looking at the latest test results we see that Vodafone is constantly improving their network, plus their indoor coverage is getting better and better. EE are still the best network for voice calls, but Vodafone is really close. At the end of the day, whichever network has a mast closer to your location will offer the better coverage for you though.

Faster call setup times and much better audio quality are the two key reasons why Vodafone and therefore ASDA Mobile ranks as the second best.

Wi-Fi Calling & 4G Calling

Being a low-cost mobile virtual network, ASDA Mobile skips voice call quality improving features such as 4G Calling and Wi-Fi Calling.

4G Calling is also known as VoLTE and it improves your voice calls drastically by using your network’s 4G spectrum rather than 2G & 3G. More data is transferred with this method so your calls are clearer and in higher definition. 4G Calling also eliminates many indoor blackspots.

Wi-Fi Calling keeps you connected even when you’re not getting any regular phone signals, provided you’re connected to a Wi-Fi network with access to the internet. These two features go hand in hand, complementing each other, but most of the MVNOs don’t offer them, because they want to keep their prices at a competitive rate.

You can check out iD Mobile’s SIM only offers if you want to get your hands on a cheap monthly rolling deal with 4G Calling and Wi-Fi Calling. Don’t forget to read our iD Mobile Review if you want to discover more about the network.

Wi-Fi Hotspots

Some UK Mobile network providers like BT Mobile, O2 and Virgin Mobile offer Free Wi-Fi Hotspots, but most others don’t. Unfortunately, ASDA Mobile falls in with the “others who don’t” category but this is one of the reasons why ASDA Mobile is able to offer competitive pricing whilst still offering the fastest data speeds in the market.

BT Mobile offers the largest number of free Wi-Fi hotspots out of all the UK operators. If having access to free Wi-Fi across the country is important to you, it’s worth checking out our BT Mobile Review.


Tethering is using the data you have on your SIM and creating a mini Wi-Fi hotspot to connect other Wi-Fi enabled devices to the internet. However, these connected devices will directly use your mobile data and you’ll be burning through your allowance at a much faster rate.

Tethering or using your phone as a personal hotspot means creating a mini Wi-Fi hotspot for other compatible devices to connect & use the data you have on your SIM. Just don’t forget that any device connected to your phone will be burning through your data allowance. Devices like laptops and game consoles will burn even more data for the same activity than mobile devices as they’re not optimized for mobile usage.

ASDA Mobile allows you to tether freely, but we’d recommend getting a large data plan if you decide to do so otherwise you may have a bill shock at the end of the month!

If you’re expecting to tether a lot we’d recommend finding an unlimited data plan such as Three’s. Three’s unlimited plans also come with great perks like Go Roam and 5G at no extra cost.

International Roaming

Mobile network providers operating in the UK must offer inclusive roaming in the EU, there’s no way around it. ASDA Mobile offers 36 destinations in the EU to roam freely, like at home if you have a 30-day bundle. You have nothing to fear if you’re on PAYG, if you’re going abroad to the EU, you will simply pay the same call, text and data charges as you do in the UK.

ASDA Mobile is a good choice for roaming, we’ve prepared an international roaming guide if you’re interested in learning more about what other networks offer.


If you wish to become an ASDA Mobile customer then you’re in luck, because both deals are prepaid and you don’t have to undergo a credit check. You can just go into a store and get an ASDA SIM.

Super-Cheap 30-Day Bundles

ASDA Mobile offers one of the cheapest 30-day rolling bundles alongside with iD Mobile for just £5 a month. You get 750MB of data, 200 minutes and unlimited texts.

Unlimited Data Plans

ASDA Mobile now offers three different unlimited data plans that come with 5G at no extra cost, however they all have speed restrictions. Even the best ASDA unlimited data plan has a speed cap at 150Mbps, and the other two plans allow you to get 2Mbps (£20 a month) and 10Mbps (£25 a month) data speeds at max.

Half Cooked’s Overall Breakdown

  • Network Coverage and Speeds – ASDA Mobile uses Vodafone  as its network provider and offers 99% population and 90% UK geographical coverage. They also provide decent 4G data speeds thanks to their new provider, Vodafone. You can also get 5G at no extra cost with the right plan.
  • Voice Call Quality – umlaut, Open Signal and other independent testing bodies rank Vodafone as the second best network in terms of voice call quality, hence ASDA Mobile also ranks as the second best.

  • Wi-Fi Hotspots – There aren’t any free Wi-Fi hotspots available to ASDA Mobile customers.
