Cheap mobilesWhether your phone's super-glued to your ear or just used for the odd call, the chances are you're massively over-paying for the minutes and texts you use.

With 1,000s of deals up for grabs picking the right one may seem like a lottery. This guide will speedily show you how to get the cheapest contract tariff, then check for added discounts.

Quick tips before you start

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 mobile 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

Pay As You Go

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

  • No credit check
  • Can be cheaper for light users
  • No contract commitment
  • Easier to budget

How to get the cheapest contract

First work out what you need, then get the cheapest tariff, only after that 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 most, ie, text, call or web surf 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 average it. Or ring your provider and it'll usually tell you. Once you've got the info check the following:

Step 2. Find the perfect tariff

Once you know your usage you need to find the cheapest 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, 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 up to three handsets at a time is Esato. It lists full specifications for each model so you can see at a glance if it has what you need.

Choose the right comparison service

Most accurate results

For accurate results billmonitor* finds the best tariff by accessing your online bills (doesn't include Three Mobile or Virgin).

Provide it with log-in details of your online account and it calculates average usage over the last three months to find the best contract.

Ease, speed & functionality

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 what handset you want and they'll find cheap deals for it.

Extra coverage

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

Before you sign up - check coverage

Before committing, check signal strength in the place you use your phone most. No coverage isn't grounds to return your phone (outside normal Consumer Rights), it's your responsibility to check.

Providers all have maps to indicate what 2G coverage is (for basic calls and texts) and some have 3G coverage too (for web surfing), although providers tend to be generous and over estimate signals. Ofcom also has a PDF map detailing 3G coverage.

The providers make it clear these maps do not guarantee coverage. There are two ways to check before you buy. One is to borrow a friend's phone if they're on the right network. Alternatively most providers offer free PAYG Sims. Nab one and test it in all the places you use your mobile most:

T-Mobile and Orange now give access to each other's network free, so if you're on either, cross-check the maps.

Step 3: Get the right discount

Now you know the correct tariff; the aim is to re-use the comparison services this time finding 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 top cashback/freebie deal - 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 & MobilePhoneChecker win

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

On MobilePhoneChecker, simply click on the drop down "view offers" and it will show you which retailer offers cashback or gifts with that specific tariff.

On Omio, to find deals click on the tariff for more details and then "see all deals for this 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 and monthly fee but it's most important to understand the difference between these:

  • Redemption cashback. The big discounts come in the form of a 'cashback redemption' that has to be claimed from the retailer, yet they're notoriously unreliable (see beating the cashback trap below).
  • Automatic cashback. These are cashback deals where you're sent a cheque automatically without claiming. They usually don't offer as big a discount as manual cashback.

    Some deals can also be part manual, part automatic cashback; if that's the case only count on receiving the automatic amount.
  • Cashback via cashback sites. It's possible to sometimes beat the above deals with some power house cashback offers, most commonly for Sim-only deals. However, don't think of this type of cashback as guaranteed, there can be and are problems. Read the full Top Cashback Sites guide for info.
