Best SIM-only mobile phone deals

For those who don't like to be tied down

Middle of the road

T-Mobile's "Full Monty" tariff sits nicely in the middle price bracket, offering up unlimited minutes, texts and data (not including tethering) for the tidy sum of £21 per month – although you will be locked into a 12 month contract.

If you want a 30-day deal then unfortunately you can't get your mitts on the full-blown Full Monty. Instead you'll have to settle for the slightly less appealing 2,000 minutes (plus unlimited T-Mobile minutes), 5,000 texts and unlimited data for £26 per month deal - although that's still pretty good.


Normally the "Full Monty" 12 month deal is £31 per month, but T-Mobile currently has it on offer at the price shown above. This means there's little in the way of an expensive option at the moment.

It's unclear how long this offer will last, so you might want to get in quick if you like the sound of getting your own Full Monty (wink wink, nudge nudge).



Best for… those looking for "The One"

Three (or 3... clever, huh?) prides itself on "bringing the benefits of the internet to mobile", and being the first carrier in the UK to offer all-you-can-eat data plans.

Its "One Plan" is your one-stop-shop for the aforementioned all-you-can-eat data, something which is becoming increasingly popular in the world of smartphones and internet on the go.


Kicking off Three's SIM-only offering is the £6.90 per month plans, with the 12-month option furnishing you with 200 minutes, 5,000 texts and 500MB of data.

For those commit-o-phobes out there, the 30-day rolling contract will give you the same amount of minutes, texts and data at the £10 a month price point.

If you've got a little more squilla in your wallet then you're straight into Three's all-you-can-eat data territory, with £15 seeing you through 12 months and providing 600 minutes, 5,000 texts and unlimited data.

The 30-day alternative will set you back the same amount monthly, but you only get 1GB of data allowance rather than unlimited.


Coming in top of the class is Three's "The One Plan", which offers you the full shebang for £25 per month on a rolling 30-day contract.

You'll get 2,000 minutes, 5,000 texts and yep, that's right, all-you-can-eat data - om nom nom.


Best for… free Wi-Fi hotspot access

The big red, as we assume Vodafone likes to be referred to, may be last in our roundup, but this doesn't mean it offers the poorest choice when it comes to SIM-only deals.

There's still a decent array of offers available here, with a clear definition between featurephone, smartphone and BlackBerry deals on its site - with the BlackBerry offers matching the price of the smartphone tariffs.

Vodafone not only offers 30-day, and 12 month contacts, with an additional 90-day option available as well, plus 750MB of free BT Openzone Wi-Fi access on all SIM-only plans.


Starting at the bottom of the price range, Vodafone's first tariff will set you back £10.50 per month and is available on 30- and 90-day rolling contacts, as well as the one year option.

You will get a slightly different set of allowances depending on the contract length you select. So 30 days will see you net 50 minutes, unlimited texts and 100MB of data, while 90 days will give you 100 minutes and the same texts and data.

Opt for 12 months and you'll get a more inviting 300 minutes, unlimited texts and 500MB of data.

If you want a bit more bang for your buck then check out the £20.50 deals, which once again vary in terms of allowance, depending on the contract length.

A 30-day rolling contract will get you 300 minutes, unlimited texts and 500MB of data, while if you plump for the 3 month contract you'll get 400 minutes plus the texts and data of the 30-day option.

Finally, if you are able to hold out for a full year, your £20.50 will provide you with 900 minutes, unlimited texts and 1GB of data.


In the top bracket of Vodafone's offering sit a 30- and 90-day deal, both of which will set you back £31 per month.

Opt for 30 days and you'll receive 900 minutes, unlimited texts and 1GB of data, while the 90 day contract will see the minutes bumped up to 1,000.

If 1,000 minutes is still not enough for you, then check out the £26 per month, one year contract which will furnish you with 3,000 minutes as well as unlimited texts and 1GB of data.
