Benefits of SIM-Only Deals

When deciding on a mobile network, it can be difficult to decide between a phone contract or a SIM-only plan. Sure, a new phone every few years can be tempting, but these bundles could be costing you a lot of money in the long run, and once you’ve signed-up you’ve got no freedom or control. We’ve put together some of the top benefits of going SIM-only, so you can figure out if it’s the right choice for you.

SIM-only versus Contract

With a phone contract, you pay a fixed monthly fee for 12 to 24 months. This bill will include your tariff (so the amount of data, texts and calls you’ve chosen to pay for) and the cost of your handset. So you are paying for your phone and network usage at the same time. 

A SIM-only plan means you are only paying for the tariff itself. For this type of plan, you should already own a handset to use the SIM with. While it can seem like more to pay initially, it results in less a month compared to a contract. 


Comparing like for like, a SIM only deal is cheaper than a phone contract.

Your monthly bills will typically end up lower because you already own your handset and won’t be paying for it alongside your data, texts and minutes. Buying a handset outright is almost always cheaper than having the price included in a 12-24 month deal, as providers often charge more for the convenience of spreading out payments. 

Asda Mobile bundles start from just £5 for 750MB of data, 200 minutes, and unlimited texts. 


You can find short-term SIM only deals which offer you ultimate flexibility. 

With a 30-day bundle, you’re not tied into a lengthy contract, so you don’t have to commit to a deal for two years. At Asda Mobile, you can switch your bundle every month to suit your needs.

By choosing your allowance each month, and not being locked into a contract, you get to pick and choose what you do with your phone, and what network you want to be with. This flexibility allows you to save money, as you only pay for exactly what you need and can shop around for a better deal. There are options for everyone, from heavy data users to unlimited texts. 


With a SIM-only deal, you’ll need an unlocked handset. If you have bought a phone that is locked to a network and you want to switch providers, learn how to use a PUK code to unlock your phone

With your unlocked handset, you have the freedom of choosing any network you like. EE, who powers the Asda Mobile network, has the fastest 4G speeds in the UK. 

Our network also allows you to use your texts, calls and data abroad.
