Would pay-as-you-go be cheaper?

The days where PAYG tariffs were only cheaper for lower users are long gone. PAYG phones are now far more competitive, with contract-style bundles available when you top up by a minimum amount.

The main reason for choosing a contract is wanting a new handset, as they're heavily subsidised on contracts. But be careful you're not paying for it with a higher monthly premium.

Contract

Pay a monthly fee and get an inclusive bundle varying in minutes, texts and data.

  • Smartphones cheaper with a contract
  • Often better for heavy texters/callers
  • More likely to get free mobile data
  • No risk of running out of credit

PAYG & Sim only

No fixed contract, pay for what you use via top-ups, online or on the phone.

  • No credit check for payg
  • Can be cheaper for light users
  • No contract commitment for payg (30 day rolling for sim only)
  • Easier to budget

How to get the cheapest contract

First work out what you need, then get the cheapest tariff. Only after that should you find the deals. It's a simple three-step plan:

How to get the cheapest contract

Step 1. Pinpoint your exact usage

Knowing how much you use your phone and what you do with it the most is crucial to getting the best plan.

Match free mins/texts closely to your usage. If you don't, go over and you'll overpay for calls. Go under and you'll overpay on the package.

The easiest way to check usage is to simply dust off your last 3-6 months' bills, jot down what you use every month and then work out the average. Or if you ring your provider, it'll usually tell you - you may also be able to check online. Once you've got the info, check the following:

How many minutes or texts do you use?

How much do you use the web?

Step 2. Find the perfect tariff

Once you know your usage, you need to find the cheapest and best mobile phone tariff to match it.

Give yourself some leeway, as a slightly higher monthly fee will be cheaper than paying extra call costs.

Are you happy with your existing handset?

If you already have a decent handset in good nick, you'll get a far cheaper deal if you opt for Sim-only. Here you simply get the Sim card with the tariff, and no handset.

If you want a new handset, first think about what features you want and will use. A useful site that allows you to compare handsets is GSM Arena. It lists full specifications for each model so you can see at-a-glance if it has what you need.


The top comparison sites: Best for finding Sim-only deals

Billmonitor

Offers the most accurate results

Billmonitor*

For accurate results, Billmonitor* finds the best tariff by accessing your online bills (it doesn't include Virgin Mobile).

It'll ask for login details for your online mobile account. Once you've entered those, it'll calculate your average usage over the past three months to find you the best contract.

It makes the assumption your habits won't change, but does pick a tariff slightly above your needs to make allowances if it does (going over your tariff can be costly).

Is it safe to give your login details?

Billmonitor says it follows a robust data security policy which it's outlined to the telecoms regulator Ofcom, and encrypts all users' passwords.

CompareMobileDeals.com

For wider coverage

comparemobiledeals.com

CompareMobileDeals.com includes some smaller retailers and networks, so sometimes trumps Billmonitor on price. However, the site's slightly clunky and we have no user feedback on it.

It's also worth noting that MobilePhoneChecker*, MoneySupermarket* and Omio* also let you compare Sim-only deals, so they're well worth a try too.


The top comparison sites: Best for any handset

MobilePhoneChecker

For extra coverage

mobilephonechecker*

MobilePhoneChecker* covers some smaller networks and retailers that the others don't, so it's worth checking too.

It also has an excellent filtering system so you can clearly pick and choose what you want.

MoneySupermarket

For belt and braces

moneysupermarket*

For ease of use and if you want a quick hit, MoneySupermarket* and Omio* come top. Simply pick monthly cost, minutes and texts for the cheapest tariffs.

Crucially, you can tell both sites which handset you want and they'll find cheap deals for it.

MoneySupermarket just pips Omio to the post as it lets you filter deals including data. Also, Omio doesn't automatically sort by cheapest price, so make sure you change the dropdown.

But Omio lets you sort tariffs further, by phone features and operating system (eg, Android, iPhone or Symbian). You can also sort by network (useful if your coverage is hit and miss), brands and style of phone.

Before you sign up - check coverage

Before committing, check signal strength in the place you use your phone most. Having no coverage isn't sufficient grounds to return your phone (outside normal consumer rights), so it's your responsibility to check.

Providers all have maps to indicate what 3G and 4G coverage is, although providers tend to be generous and over-estimate signals. If you're looking for 4G, most providers have their own coverage checkers online so double-check before you sign up.

4G - do you need it?

Most providers now offer 4G but before signing up, remember you'll need to have a 4G-ready handset and live in an area with 4G coverage.

4G offers a lightning-quick internet connection for mobile devices. You’ll be able to browse the web, download music and movies, and play games on your phone at speeds up to five times faster than 3G.

However, it’s still a relatively new technology, and therefore a bit more expensive than 3G.

If speed isn't important to you, it's not essential. Also keep in mind if you travel around a lot, you'll need coverage in each area you visit.

Can you return a phone if you can't get coverage?

Samsung phones and iPhones

The sites above will help you find the cheapest tariff for most mobiles. But if you're after a swanky smartphone, it's worth checking out the Cheap iPhone Tool and Cheap Samsung Galaxy Tool to view our top picks and find the best deal for your usage.

Step 3: Get the right discount

Now you know the best mobile phone tariff for you, use the comparison services again. This time, find out which will give you the biggest discount on your chosen tariff. Don't be tempted to switch to a different tariff to get a freebie - let the tariff rule.

Always pick the right tariff first. Then even if your promo falls through, as many have, you're still on the cheapest package.

Omio* and MobilePhoneChecker* both allow you to find the right tariff and then search for specific deals for that tariff.

On Omio, to find deals, click on the tariff for more details and then "see all deals for this tariff".

On MobilePhoneChecker, simply click on the "view offers" dropdown. It'll show you which retailer offers cashback or gifts with that specific tariff.

The mobile market is rife with a variety of discount packages, meaning the same tariff on the same network can cost vastly different amounts. Discounts include free gifts, but it's most important to understand the difference between these:

Redemption cashback

Automatic cashback

Cashback via cashback sites

Beat the cashback trap

Cheap Sim-only deals

If you're happy with your mobile handset, it's well worth looking at Sim-only deals as a cheaper alternative. Unless you're already with the sim-only tariff provider (GiffGaff will work if your phone is locked to O2 too), you'll need to get your phone unlocked. Our Mobile Unlocking guide has full help if that applies to you. Here are our top picks:

Giffgaff

Goodybags start from £5/mth for 60 mins, 300 texts and 20MB

Giffgaff* - good for medium users

Sim-only provider Giffgaff* offers top-up bundles which are as good value - if not better - as some contracts.

The bundles, called Goodybags, start from £5/mth and go all the way up to £18/mth. Here's a breakdown of what each bundle will get you. The cheapest bundles have very low allowances, so check what's included before you buy.

  • £5/mth Goodybag. 60 mins (plus a free extra min for every min you get called by a non-Giffgaff number), 300 texts, 20MB data, unlimited Giffgaff-to-Giffgaff calls/texts.

  • £7.50/mth Goodybag. 200 mins, unlimited texts, 250MB data, unlimited Giffgaff-to-Giffgaff calls and texts.

  • £10/mth Goodybag. 500 mins, unlimited texts, 1GB data, unlimited Giffgaff-to-Giffgaff calls and texts.

  • £12/mth Goodybag. 500 mins, unlimited texts, 3GB data, unlimited Giffgaff-to-Giffgaff calls and texts.

  • £15/mth Goodybag. 500 mins, unlimited texts, 5GB data, unlimited Giffgaff-to-Giffgaff calls and texts.

  • £18/mth Goodybag. 2,000 mins, unlimited texts, unlimited data, unlimited Giffgaff-to-Giffgaff calls and texts.

These are their standard goodybags, which come with 3G data. Giffgaff now also offers the following 4G goodybags*.

  • £12/mth 4G Goodybag. 500 mins, unlimited texts, 1GB data, unlimited Giffgaff-to-Giffgaff calls and texts.

  • £15/mth 4G Goodybag. 500 mins, unlimited texts, 3GB data, unlimited Giffgaff-to-Giffgaff calls and texts.

  • £18/mth 4G Goodybag. 2,000 mins, unlimited texts, 5GB data, unlimited Giffgaff-to-Giffgaff calls and texts.

Is it any good? The standard rates for Giffgaff aren't quite as cheap as the Three deal below. But if you're an average or heavy user, getting a Goodybag is good value for money.

Virgin Mobile

Sim-only deal gets unltd mins, unltd texts and 3GB data for £15/mth

Virgin Mobile* - good for all-round heavy users

If you're practically glued to your phone, Virgin Mobile's* £15/mth Sim-only tariff gives you unlimited minutes, unlimited texts and 3GB data/mth. It's on a 12-month contract, or you can opt for a 30-day rolling contract for £20/mth.

Few people need unlimited minutes and text, so consider if it's really worth paying for. It's available on standard, micro and nano Sims - there's a 99p delivery charge for the Sim, though this is free if you've got Virgin Media cable. If you want monthly bills by post, it's an extra £1.50/mth.

To see this deal, click the link above, then click 'No I don't', when asked if you've got Virgin broadband, TV or home phone. If you're already a Virgin Media customer, you can get this plan on a 30-day rolling basis without the increased price-tag - ie, for £15/mth instead of £20/mth.

You can use your existing handset, but only if it's already on Virgin's network or unlocked. Read the Mobile Unlocking guide for full help if your phone needs unlocking.

Virgin Mobile

Sim-only deal gets 200 mins, unltd texts and unltd 4G data for £15/mth

Three* - good for heavy data users*

If you're looking for a cheap deal with lots of 4G data, Three's* £15/mth Unlimited VIP Sim-only tariff gives you 200 minutes, unlimited texts and unlimited data on a 12-month contract.

Free calls to 0800 is also included with this deal. If your minute allowance runs out you will be charged 35p/min.

You'll also be able to use its 'feel at home' feature (see our guide to data roaming for full details) which allows you to use your phone in 16 countries, including the US, Australia, France and Italy, at no extra cost. If your phone can be turned into a WiFi Hotspot you can tether your device but tethering comes with a data allowance of 4GB/mth.

It's available on standard, micro and nano Sims and will be delivered without charge. You will need to pass a credit check to get it though - see our Credit Scores guide for how you can boost yours.

Tesco Mobile

Sim-only deal gets hearty 1500 mins, 5,000 texts and 500MB data for £10/mth

tesco mobile* - good for those who like to chat

With a decent allowance across minutes, texts and data, this is a good all-rounder. On a 12-month contract, Tesco Mobile* is offering 1500 minutes, 5,000 texts and 500MB of data for £10/mth. Plus, providing your phone is 4G ready, it's included with this offer.

It doesn't matter if you've a flash or ancient phone; handily, it's available in standard, micro and nano Sim sizes. If you manage to eat your way through its inclusive allowance, it's 10p/MB for data, 25p/min for calls to UK mobiles or landlines, and 10p per text.

Cheap PAYG tariffs

Looking for a bargain-basement PAYG deal? Here's the cheapest deal we found:

Three

Call for 3p/min, text for 2p/text and browse the web for 1p/MB

three 321* - for low users/emergency phone

The 321 tariff from Three* does just what it says on the tin - it's a simple and cheap tariff, charging on a pure pay-as-you-go basis. It's a cracking deal for occasional mobile users, as it's by far the cheapest PAYG rate on the market.

It's a Sim-only deal, so you'll need an unlocked or Three handset to put the Sim in. It'll only work in 3G-compatible handsets.

How much is it? Top up with £10 and you it costs 3p/min for calls, 2p/text and 1p/MB for mobile data (though the first 150MB after each top-up is free).

The credit will stay on your phone for six months if unused, so use your phone occasionally and it'll stay on permanently.

For someone using their phone a decent amount, a Giffgaff* Goodybag bundle is cheaper. These are monthly add-ons, so for example, for for £7.50/mth you get unlimited texts, 200 minutes and 250MB.

Can I add extras on? If you want extras, such as "all you can eat" data, you can add these whenever you need (see the Three website for info).

Typical £10 PAYG rates compared

Texts 2p/text Unlimited 400 texts 400 texts 1000 texts Unlimited
Data 1p/MB 500MB 1GB 1GB 500MB 1GB

Granny in a glovebox - grab a cheap emergency phone

A ‘granny in a glovebox’ phone is great to stash in your car as an emergency second mobile, to give to your kids or if you only need to use a phone very occasionally.

One of the cheapest we've found, which doesn't need to be topped up often, is the unlocked Samsung E1200* from Tesco Direct for £15. Since it's unlocked, you can pick up a PAYG Sim from any of the networks and use it. The cheapest from Three* requires a £10 top-up - calls are 3p/min, texts are 2p each and data costs 1p/MB (after the first 150MB, which is free)

After that you only have to use the Sim once every six months - one quick call will do - to make sure the credit doesn't expire.

If you're after a phone with web access, a cheap smartphone on a pay-as-you-go contract is the Samsung Galaxy Y* at £49 (£3.95 p&p) from Very. Again, it's unlocked so you'll need to buy your own Sim-card.

Free or cheap texts from your mobile

If you're a textaholic without inclusive texts - or if you're travelling abroad - then it's worth knowing about the hidden ways to send texts for less.
