Network Coverage & Speeds

ASDA 4G Coverage

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 voice calls and also as a fallback 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.

ASDA 4G Speeds

Opensignal’s September 2021 speed test results state that Vodafone and ASDA customers get average 4G download speeds of around 21.6Mbps; the network’s upload speeds are around 7.4Mbps. These data speeds are more than enough to stream high-quality videos and listen to music.

ASDA 5G Coverage

ASDA Mobile’s SIM only deals come with 5G at no extra cost and at the time of writing, ASDA 5G is live in 123 UK towns and cities. You can also enjoy 5G roaming abroad, which we’ve covered in more detail below.

We’d like to remind you that you’ll need a 5G-ready handset to get 5G coverage.

ASDA 5G Speeds

Per Opensignal’s September 2021 test results, ASDA’s average 5G download speeds are around 73.3Mbps, and their 5G upload speeds average around 12.3Mbps. While ASDA Mobile itself wasn’t tested, the carrier’s 5G experience is identical to Vodafone 5G, unless there’s a speed cap that comes with your choice of SIM plan.

Objective testing bodies rank Vodafone as the slowest 5G carrier, but these data speeds are still fast enough to stream 4K videos without any hiccups.

WiFi Calling and 4G Calling

ASDA Mobile customers enjoy both WiFi Calling and 4G Calling at no extra cost. Nowadays, these two voice call perks are somewhat essential, and they significantly improve your coverage, whilst eliminating indoor blackspots. ASDA WiFi Calling and 4G Calling will only work with handsets that support them.

All ASDA Mobile customers are eligible for free 4G Calling. This feature is also known as “Voice over LTE”, and it allows you to make calls using data. The main benefit of 4G calling is its high-definition audio quality compared to standard network calls.

ASDA Mobile helps you take your connection to the next level by offering free WiFi Calling. This feature allows you to send and receive text messages or phone calls completely through a Wi-Fi connection, rather than relying on a mobile network signal. All you need is a compatible phone and you’re good to go!

When you turn on WiFi Calling alongside 4G Calling, your phone will automatically move between WiFi and 4G data to keep the call connected.

Personal Hotspot

You can tether freely on ASDA Mobile. You can tether another mobile phone, laptop or tablet to your handset. Not all wireless devices are compatible so make sure to check the compatible devices list first. Also keep in mind that some fair usage may apply to some ASDA Mobile plans, and some plans come with speed restrictions.


5G Roaming

ASDA Mobile offers 5G at no extra cost in over 100 UK locations, but their 5G service doesn’t end there. The carrier also offers free 5G roaming in Germany, Italy, Spain, and Ireland. More countries are expected to follow very soon.ASDA Mobile offers 5G at no extra cost in over 100 UK locations, but their 5G service doesn’t end there.

No Credit Checks

ASDA Mobile is a commitment-free mobile network, which means there are no credit checks or contracts involved. You just pay up front and you can start using your allowances right away unless of course, you’re carrying over your number to ASDA Mobile. In that case, you may have to wait a day or two before your new SIM becomes fully usable.

Half Cooked’s Overall Breakdown

ASDA Mobile offers competitively priced SIM deals that offer amazing value. The network’s main goal is to keep its customers connected by offering free 4G Calling, WiFi Calling, and 5G. Their PAYG rates are one of the best in the country.

Just keep in mind that you won’t be getting some of the additional perks you would with some of the larger networks. We give ASDA Mobile 4 stars out of 5 and we can recommend them if you’re looking for a reliable and cheap provider with no fancy features.
