  • Receive your SIM the same time as your ‘Quality guaranteed’ smartphone
  • Use our SIM calculator to find the best deal and price across all the major networks
  • Save up to £250 compared to a 24 month directly from a network
  • Buy before 3pm for next day delivery

Our free SIM cards come in all 3 sizes (micro, nano and standard), all you need to do is pop out the SIM that fits your phone.

SIM-Only Deals

Perhaps you’ve paid off your handset. Or maybe you’ve bagged a smartphone upfront to save money in the long run. Either way, we don’t need to tell you how many amazing SIM-only deals there are on the market. Looking to compare SIM-only deals online? You’ve landed in the right place.

Perhaps you’ve paid off your handset. Or maybe you’ve bagged a smartphone upfront to save money in the long run. Either way, we don’t need to tell you how many amazing SIM-only deals there are on the market. Looking to compare SIM-only deals online? You’ve landed in the right place.

What do we mean by ‘SIM-only’?

Many people who buy a flashy new smartphone through one of the big providers enter a contract. They pay monthly instalments for an agreed period (usually 24 or 36 months), where part of the handset cost covers network services.

SIM-only is different. In these situations, you don’t get a handset. You’re not tied into a monthly contract to cover the cost of a device—instead, you pay for a SIM card that has a flat monthly fee. You’ll get an agreed allowance typically consisting of data, calls, and texts, but no smartphone.

What are the benefits of SIM-only plans?

If you’re happy with your current phone contract, you might ask what the big deal is. Well, SIM-only offers flexibility and savings in the long run, especially if you buy a refurbished phone.

The best SIM-only deals offer:

  • Shorter contracts – in many cases, you’re free to chop and change your plan regularly, with minimum contracts starting at 30 days.
  • Tailored terms – only pay for what you need.
  • Flexibility – discover SIM plans from a wide selection of providers outside the big four networks.
  • Great prices – Find out how much you could save with our SIM Calculator.
  • More options – choose from unlimited data plans and receive extras.

Where can I compare mobile SIM-only deals?

Looking for a cheap SIM-only plan? You’re already in the right place. Whether you’re buying a refurbished phone and need a network, or you’ve already got your handset, start your search right here. Browse fully flexible contracts from 30 days up to 12 months, below:

  • Virgin Mobile SIM-only plans
  • Lebara SIM-only plans
  • O2 SIM-only plans
  • Three SIM-only plans

Why choose Envirofone?

We’re confident our bargain SIM-only plans won’t be beaten on price. So, whether you’re eyeing up unlimited data or just want a couple of GBs to keep costs down, we’ve got the goods.

But that’s not all. When you buy with us online, you’ll receive next-day delivery on all orders processed before 3PM. In other words, you’ll be WhatsApping and streaming tunes in no time.

Fancy a refurbished mobile phone?

You won’t get very far with your new SIM card if you haven’t got a smartphone. But, thankfully, that’s easily solved when you head to our online store. As the UK’s leading phone recycler, we’ve got thousands of refurbished handsets on offer, including flagship models from Apple, Samsung, Sony, and more.

Worried that second-hand means second-rate. Don’t fret. All our products are put through a 100-point quality check before arriving at your front door. But that’s not all. For added assurance, we give you a 12-month warranty and 30 days to return your phone if it doesn’t work as expected. So, what are you waiting for? Grab a fantastic deal on a good-as-new handset to go along with your low-cost SIM.
