Pay-as-you-go vs. Contract
A common question - what should you go for... Pay-as-you-go, or Contract, for your next phone?
Well, pay-monthly contracts works for some people, pay-as-you-go works for others. It depends on your usage, finances and comfort-level. The best way to control your spending is pay-as-you-go, but the charges are generally a little higher, and there are less special offers, as the network operator would rather tie you in for the long term.
We recommend that the first thing to do, is to look at your current or proposed spending (voice calls and text messages), and compare against a tariff.
Free SIM cards

I'm being asked for my PUK. What does that mean?
PUK stands for 'Pin Unlock Code', and has to be entered if you've locked your SIM by repeatedly entering the wrong PIN code. If you're asked for a PUK code, you've had more goes at guessing your SIM card PIN code than you're allowed.
You'll need to phone your network provider Customer Services for your PUK code to unlock the SIM. For security reasons, it's only the network operator that can legally provide you with a PUK code to unlock your SIM.
How do I find out my own mobile number?
If you've got a SIM card for a mobile, and don't know what the phone number is - the easiest way to check, is to use the card to phone a landline phone number, and then from that landline phone, dial 1471. Caller identification should then repeat the number to you.
Alternatively, call Customer Services from the mobile - they should be able to see your number.
My phone is network locked
If you've bought a second-hand mobile, or have changed networks, you may find that you're unable to use the handset with a new SIM card - you may be prompted to enter a "restriction code", "network code" or "subsidy code", or get a message telling you that you can't connect to a certain network.
This is likely to be because the handset is "locked" to a particular network. This is something done by network operators to ensure that their handsets aren't sold on, or used on other networks, until the user's contract ends. When you sign to a contract, you normally get a discounted (subsidised) handset, and the network operator ties you in to a contract for at least a year, so that they make enough money to pay for the cost of the discounted handset.
There are various ways of "unlocking" a handset that's locked to a network - most of which involve connecting cables to your phone and using unapproved software, or paying money to disreputable sources - but this is not something that the network operators offer, support, or condone. The correct way to handle this is to contact the network operator that's locked the phone to get an unlock code - there may be a charge for this.
Using your handset overseas
If you want to use your handset overseas, there are two things you need to bear in mind: You must have your phone set to "International roaming". You need to contact your mobile phone network provider to ensure that this service is enabled for your phone Your handset must work on the frequencies in use in the country you'll be travelling to. UK users should look for a tri-band phone - these operate on EGSM900/1800 (Europe, Africa, Asia Pacific), and GSM1900 (USA, Canada, South America), or for better global coverage, a quad-band phone.
What is SMS?
SMS stands for Short Message Service, but is more commonly known as "texting". Text messaging is of course hugely popular, especially where you consider that the Network Operators never expected it to be a hit - in fact it was 'launched' by accident. Mobile Phone Network Operators used a spare data channel to send each other messages, and it caught on. Improvements to the service, such as T9 predictive text (to help type faster), have helped to improve the service, and a number of enhancements such as enhanced messaging (EMS) led to MMS multimedia messaging (messages with video, photos and sound).
As well as sending text messages to friends, SMS messages can be used by your operator to send you phone settings over-the-air and software, for companies to send dedicated content (and spam) to your mobile, and for services such as online voting, news alerts and competitions.
What is MMS?
MMS stands for Multimedia Messaging Service, and more commonly referred to as 'Picture Messaging'.
MMS beats the standard SMS text message as it adds animation, images, sound and video.
With an MMS-enabled phone you can:
Take digital photographs and store photographs on the Internet
Send and receive full colour pictures
Send and receive voice clips
Add a text message to your picture
Purchase pictures and sounds from the Internet
Have enhanced polyphonic ringtones
What's 3G all about?
3G was launched in the UK in March 2003 by the network operator 3. The other UK network operators later launched their their 3G services.
3G stands for the "third generation" of mobile phone handsets... (1G was the old analogue system, 2G was the digital handsets that we were using a few years ago, with 2.5G representing handsets with data capabilities over GPRS).
3G is all about data, and letting mobile phones and mobile computers surf the 'net using Broadband speeds over a mobile phone network. The features you can get from 3G are as follows:
Super-fast surfing and downloads: 3G offers speeds in the Megabit range not the Kilobit range - offering a much faster download service than we've been used to in the UK.
Download video: This was the big selling point when 3G launched - the ability to watch streamed video clips on your handset - this can be live TV, sports snippets, music, news headlines, weather forecasts, adult content, or movie trailers.
Video calls: Make and receive video calls to/from other 3G users. See who you're talking to in real time
Pictures: 3G phones can take still digital pictures as well as coping with video. You can send photos to other 3G users, as well as to users with non-3G phones that use MMS. Data speeds are considerably faster than a standard 2.5G MMS phone.
Location-based services: See a map of where you are, and where to find nearest shops, banks, etc (more). Some handsets, like the Apple iPhone have built-in GPS for navigation
Games: Download games up to 30 times faster than on a standard GSM phone, and play online games.
What is Bluetooth?
Bluetooth is a wireless technology that allows computers, phones and other devices to talk to each other over short distances (up to 100 meters). Bluetooth uses radio waves (in the 2.4 Gigahertz range), and is designed to be a secure and inexpensive way of connecting and exchanging information between devices without wires.
You'll find Bluetooth in many of the newer mobile phones, handheld computers, laptops, printers, handheld organisers, as well as in all sorts of products.
Uses of Bluetooth include: sending photos from your mobile, exchanging business cards, sending voice from a headset to a mobile phone, and real-time satellite navigation using GPS.
What can I do with infrared?
Many phone handsets now come with infrared (IrDA) built-in. By lining up the infrared 'eye' with other devices, you can send data.
What is GPS?
GPS receivers are able to obtain their location by acquiring a signal from some of the 27 satellites that orbit the globe. The GPS system, originally for use by the US military, is now available to all for location-finding and navigation. With a GPS receiver, road warriors, pilots, ramblers, and nautical folk can find out where they are, plan routes, help get on the wrong track when lost, and generally make travelling a whole lot easier. A GPS receiver makes use of signals received from the satellites, using three or more to pinpoint your position. Obviously, you need line-of-sight for this to work, so your receiver must be able to see the sky.
