The downside of course is that you might not get the best deals on the call and text rates, and you have to either already have a phone, or buy a pay as you go model. Whilst the contracts many people opt for include a free mobile handset, the pay as you go tariffs very rarely offer a similar incentive to join. Instead you might like to look at some alternative options which we look at in our article on how to get a free mobile phone, as well as how a new handset might actually be cheaper than you think!

A few short years ago, the thought of full Internet access on a mobile phone seemed like something in a sci-fi movie, but we are now in a position where some people get a faster connection to the Internet through their mobile that their land line.

Technology moves on, and in the future it seems logical that we’ll receive many more services via the Internet, but what are the mobile companies working on with the hard earned cash we send them every month? Our article on the mobile networks takes a closer look.

Of course, if you only call abroad occasionally, you might be better off on a more mainstream tariff. As usual you will need to work out your usage patterns when choosing a mobile plan, so taking a look at our article on international sim card tariffs might help you.

A good solution is a sim card reader which allows to to take a copy of the information on your sim card. If you’ve lost your phone this might be of little relief, however it may rescue the information from a sim card in a phone that has been dropped and smashed or been put through the washing machine.

If you’re yet to lose the information, better still, as you can get a reader to keep them safe just in case. All you do is buy a device for around £5 and plug it into your computer. The sim card can then be read by special software on your computer.

In today’s update, we have gone into detail on the Micro Sim, including how it’s actually the third generation sim card. You’ll also find out how to use a standard sim with an iPhone or iPad, although it’s not a good idea!

Here’s today’s article on the micro sim card.

Today’s article goes into depth on exactly what you get from each of the five free o2 sim tariffs, to help you choose the one that’s right for you. They vary from simple calls and text message allowances to international calls and blackberry users.

Once your contract expires, you should always be looking to save money, or get a new phone. If you want to keep your current handset (or save a few quid!) then looking for the best sim only deals may be your best option.

You will need a rough idea of your usage and you can get started. If you can find a better deal on the same network it’s usually a simple switch. If another network is cheaper you may need to get your mobile phone unlocked, which often incurs a fee, but this is loads cheaper than sticking with your contract in the long run!

We look at why sim free exists, and why you should buy one when they plainly look expensive next to contract phones or pay as you go phones sold by the networks themselves.

If you’d struggle to explain the difference between a pay as you go phone and a sim free phone, today’s article on sim free phones is likely to make a good read for you!

Some people sell their old handsets to companies that recondition them and resell them in less developed parts of the world, which you might think is a great deal when it makes you a few quid. Of course, the third world countries are very deserving recipients, but there is another option that will be even more beneficial to your pocket.

You will no doubt be aware that when a mobile contract ends, or more likely a month before that, your provider will be keen to get you to take a new handset from them, which they make out they are paying for. In reality you are paying for it through your monthly fee, but people don’t always realise this, as they always remain on the same tariff.

On a phone contract, your monthly fee is made up of two components. A percentage pays for your tariff, in other words the number of minutes and texts that are included, as well as any data allowance. The part the networks are less keen to talk about is the remainder, which pays for the phone itself.

If, when your contact ends, your phone is still in decent condition, you can choose to hang on to it for a while, and pay less each month whilst retaining the same allowances. This is called sim only. Naturally, your mobile network won’t advertise this – if you do nothing they’ll continue charging you as if you were still in your minimum contract period.

Just call your provider and make the switch. You can often do this a month before the end of your contract, and you’ll need to commit to a minimum period. However, if you stay with the same network, they will likely let you end your sim only contract at any time if you take a new handset on contract with them, with no penalty to pay.
