Sim only Ultimate Guide

When you buy a typical mobile phone contract you are paying for two things: the handset and the airtime (minutes, texts and data). A SIM only deal means you only get and pay for the airtime part. This is typically much cheaper than a mobile phone contract and another bonus to SIM only is that you aren't tied down by any lengthy contracts.

Save money

One of the most attractive features of switching to SIM only is its cost effectiveness in comparison to mobile phone contracts. SIM only is a great way to reduce your mobile spend as you aren't paying towards a phone that's worth hundreds of pounds.

You can order a free SIM card from Asda mobile and start saving money instantly. Whether you choose PAYG or our monthly bundles, we offer amazing value for money.


Monthly SIM deals give you the freedom and flexibility with the option to keep them recurring. With Pay as you Go you can swap your phone whenever you like. You don't need to sign up to any length of contract. If you want a new phone due to your old phone being damaged or outdated, you can simply purchase one as long as the phone is unlocked.

You're in control

The great advantage our mobile bundles have is that you aren't tied into any contracts, meaning you can choose which bundle you'd like every month. If you find yourself craving more data you can upgrade, or if you aren't using all your allowance you can downgrade - ultimately, the choice is yours!

If you want more data while travelling to the EU, you can add one of our data bundles or try our incredible £10 bundle which now offers 7GB of data! Check out our monthly bundles today and join the family!

SIM cards come in three different sizes.

Standard SIM

This is the largest SIM (25mm x 15mm) and is used in phones from the 90s and early 00s.

Micro SIM

This medium-sized SIM (15mm x 12mm) was introduced in 2010 and is used in older smartphones such as the iPhone 4.

Nano SIM

Introduced in late 2012, this is the smallest SIM (12.3mm x 8.8mm) and is usually used in phones released over the last 3-4 years, such as iPhone 5 and above. All of these SIM card sizes are supplied when you order a free SIM from Asda mobile. When you receive your SIM pack simply see which SIM fits into your phone or tablet SIM card slot. To read more about SIM Cards read our article on everything you ever wanted to know about SIM Cards.

SIM cards are tiny and therefore incredibly fiddly things to change - in particular Nano SIMs. To change your SIM card, you will need a SIM tool (small metal pin).

Find the small hole on the side of your device and use this pin to pop your SIM card tray out. Place your SIM card chip-side down onto the tray and slide the tray back into your mobile phone. When you turn your phone on, your phone will recognise that this is a new SIM and prompt you to set it up.

Our monthly bundles are the cheapest way to obtain calls, texts and data for a set price. With no contract attached, you can downgrade, upgrade or even cancel your bundle package. Here at Asda mobile, our bundles start from as little as £5. Joining us has never been easier - simply text your desired bundle number (e.g. 5) to 2732 (From the UK).

It's easy! Simply text 'AUTO' followed by the number of the bundle you want to purchase. For example, if you want the £10 bundle to recur simply text 'AUTO10' to 2732 (From the UK). For more examples, click here. For more examples of Text/Bundle Codes including information on how to STOP a recurring top up, click here.

When choosing SIM Only you have three choices when it comes to topping up: Pay as you Go, monthly Bundles and Recurring Bundles. We offer a simple and easy Pay as you Go service - all you need to do is top-up your SIM card and you're ready to go. Our Pay as you Go service follows our Standard Tariff, with calls from 8p per minute, texts from 4p and data from as little as 5p per MB. Our bundles are essentially our SIM Only Deals separate from our Standard Tariff. When you buy a monthly bundle you will get a select amount of texts, minutes and data allowance over the month. Our top bundle gives you unlimited minutes, unlimited texts and 15GB of data for just £25. For more of our bundles visit our bundles page or bundle calculator.

To keep your old number, you need to obtain your PAC code from your old UK network provider. The next step is then to call Asda mobile customer services on 2732 (From the UK) or (free of charge) from your new Asda SIM or from any other phone and provide the PAC code. It will not take more than two working days to move your number from your previous service provider to your new SIM card.

With Asda mobile, you can use our bundles in 50 European countries at no extra cost, as part of our Roam like you're home policy. Check which countries are covered here. If your destination falls outside these European Countries you can check the costs for sending and receiving calls, texts and data here.

Many providers offer 12-month contracts, however here at Asda you aren’t tied into any contract. If you have joined our network, you should try to use your SIM card at least once every 180 days in order to keep it active. As long as you do so, your credit won’t expire and your account will continue to be open.

If you join us on a SIM only basis but decide you want to purchase one of our bundle packages, then you can! It’s a simple and easy process.
