Finding the cheapest sim only offers

The costs associated with SIM only deals have dropped considerably over the past few years, with more and more networks battling it out to provide the cheapest monthly deals.

What size sim card do I need for my current phone?

Not all smartphones are alike in the SIM department, with many phones now taking different sized SIM cards. You can find out exactly which card you need by looking in your smartphone handbook, or by checking out its specs online.

30 Day Rolling Contract

If you are waiting for a new handset to arrive on the market and you are out of contract, you have an option to wait with 30 day rolling SIM only options. This ensures you are not tied down and can get out a soon as possible, exactly when you are ready.

What tariff options are there without a phone?

SIM only plans were once nothing but an afterthought for most mobile phone shoppers, with the majority of consumers instead opting for expensive deals which included smartphones as well as their tariffs. However, since smartphones have become more and more closely matched, many fans now invest in SIM only deals to ensure that they can grab the best phones the moment they arrive, rather than waiting for their contracts to come up for renewal.

Of course, if you don't want to pay a monthly fee, you can invest in a pay as you go SIM only plan. These work by having you get the SIM from the network you want, and then topping it up with the minutes, texts and data you think you'll use. These often cost very little up front, but do need you to splash the cash if your balance dwindles.

Take at the look at contract phones for business and see the simcard options there, a great option to save money for your company.

Contract SIM only deals work differently, having users pay a monthly fee at a fixed rate for set amounts of minutes, texts and data. These can vary in length and tariff, but don't require you to manually top up the card to stay in touch with your contacts. However, if you overshoot the mark, you could end up paying more than you expect - although your network will inform you when you're going overboard.

Users with existing handsets and looking for a certain size

The main advantage of SIM only deals is that you can use them with any phone that works with your chosen network. This means that if you plan on keeping your existing smartphone, you can simply pick up a SIM only plan and cram it into your device.

Of course, if your current phone is locked to your network, you'll need to arrange to get it unlocked, something which can be done by contacting your network seperately. The SIMs themselves now will be supplied from retailers and are compatible for all sizes, meaning you don't have to worry about ensuring the card will fit your phone.

If you're unsure, you can find out how to unlock your phone here.

Also, if you have a tablet which works with mobile data, you could also invest in a SIM only deal to connect it to the internet when you're out and about, giving you a larger device to access the net with should you need it.

SIM only contracts can vary massively in their length, with many deals starting with just 30-day rolling plans for maximum flexibility. Other deals go up to 12 or even occasionally 24 months, offering lower monthly costs, but obviously tying you down to a certain network for a period of time.
