If you’re keen on keeping your monthly phone plan cost down, ASDA mobile offers some reasonably-priced tariffs on their 30-day pay as you go bundles.
ASDA mobile is powered by EE, the UK's biggest network, so you can relax knowing you have the best network coverage, speed and reliability in the UK.
As ASDA Mobile is a Pay As You Go network you will only ever spend what credit you have.
What SIM-only deals can I get from ASDA mobile?
ASDA mobile offers a decent range of bundles at the lower end of data allowances, minutes and texts.
Monthly allowances range from 200MB data with 125 calling minutes and 2000 texts, up to 8GB with unlimited minutes and texts.
SIMs are available on either 12-month or one-month contracts, each of which come with their own advantages. Longer term 12-month plans cost less per month, and higher allowances are available; while one-month deals give you more flexibility.

Can I get an unlimited data ASDA mobile?
No, we're afraid unlimited data isn't available with ASDA mobile. The maximum monthly data allowance you can get is 8GB, on a one-month plan. That's still a reasonable amount of data and enough to stream an hour or two of music or podcasts over 4G every day.
However, if you don't think 8GB is enough, you may need to take a look at unlimited and big data options from other networks instead.
What's the cheapest ASDA mobile SIM-only deal?
The cheapest mobile SIM deal you can get from ASDA mobile is a one-month plan that comes with 200MB data, 125 minutes, and 2000 texts per month.
To find the cheapest deal that fits your use, use our comparison table. Adjust the filters to make sure you only see SIMs that have enough monthly allowance for you, and then sort the whole table by monthly cost. You'll see the lowest-priced deals right at the top.
You'll generally find that 12-month plans work out cheaper per month than 30-day ones, so it's worth the commitment if you really want to save money. And sometimes there are limited time deals that are worth pouncing on - keep an eye out for those.
Is an ASDA mobile SIM deal cheaper than a phone contract?
Yes - it's almost always cheaper in the long run to buy a phone outright and take out a SIM-only deal.
As all ASDA mobile SIM-only deals are one-month plans, if you do want the benefits of a longer contract (like lower upfront costs, a nice new phone in your hand today, and free screen replacements), it’s worth seeing what other networks can offer.
Can I upgrade an ASDA mobile SIM-only deal?
Yes, you can. As all ASDA mobile plans are 30-day pay as you go bundles, you're not tied into a lengthy contract, meaning you have the freedom to flex your usage whenever you need to.
Can I keep my number if I switch to an ASDA mobile SIM-only deal?
Yes - it's almost always possible to keep your current phone number when you switch to a new network.
1) Choose a new SIM-only plan - compare deals and sign up to one that you like the look of. Your SIM will be sent through the post to you. While you're waiting…
2) Contact your current provider and request your PAC (porting authorisation code) - you can request your code in a few ways - online, via text and even by post if you're really old-school. If you phone, they may try to talk you into sticking with them, but stick to your guns if this happens. They'll send you the PAC as a text message within two hours.
3) Give the PAC to your new network - when your new SIM arrives, it will have a new number. To change it to the old one, contact your network and give them the PAC code. They'll take care of porting the number over. It could be as fast as one working day before the old number's transferred, but be aware that on occasion it can take a little more time.
It may sound complicated, but it's very simple in practice. If you want a bit more detail, check out our full guide to keeping your phone number:
What size SIM card do I need?
There are three SIM card sizes you can get:
- Standard SIM card - 15mm x 25mm, commonly used in older feature phones
- Micro SIM card - 12mm x 15mm, used in some smartphones, primarily older models
- Nano SIM card - 8.8m x 12.3mm, used in most modern phones, including popular handsets like the iPhone 8 and Samsung Galaxy S8
Don't worry if you have no idea which size your phone takes. Most networks will send you a 3-in-1 SIM, designed to fit into any handset. It'll come encased in plastic, and you can pop it out into the size you want.
In other words, don't stress about SIM size when comparing deals. Whichever you choose, the SIM card will fit in your phone.
Does my phone have to be unlocked to use an ASDA mobile SIM?
Some phones are locked onto a particular network, and will need to be unlocked before you can use another company's SIM. Fortunately, this is really easy to do. To find out if your phone is locked, pop in a friend's SIM card - they'll need to be on another network obviously. If it works, then your phone is good to go - otherwise, you'll need to contact your current operator and ask them to unlock it.
Different networks have different rules on unlocking. Some examples are:
- Three - all handsets are unlocked out of the box.
- O2 - phones are locked, but O2 will unlock them for free when you're out of contract. Pay-as-you-go (PAYG) customers will have to pay though.
- Vodafone - phones are locked, but Vodafone will unlock for free.
EE - phones are locked, but EE will unlock for free - so long as you're out of contract. PAYG customers must wait 12 months after purchasing to unlock.
Those are just the major networks. To find out more about unlocking your mobile, check our full guide:
