I am being asked for a PUK number, what does that mean?

PUK stands for Personal Unblocking Key. If you have entered your PIN code incorrectly 3 times your SIM card will be blocked and you will be unable to make and receive calls.

If you are with O2 you can obtain your PUK code from their website, follow http://www.o2.co.uk/apps/getPUK/welcome

In most cases you’ll need to phone G-Force Communications Ltd or your network provider Customer Services for your PUK code to unlock the SIM.


What is my Voicemail Retrieval Number?

O2 = 901

Orange = 123

Vodafone = 121

T-Mobile = Dial 222 to get your voicemail information sent to your phone.

Dialling *#67# should tell you what your voicemail divert number is.


What is my SMS Service Number?

Below is a list of the SMS Service Centre (SMSC) numbers for the main UK operators. The SMSC is stored on your phone or SIM, and is used to forward your outgoing text messages to the network operator. If your phone suddenly loses the ability to send a text message – it could be a problem with the SMSC number stored in your phone.

Check your mobile phones “Message Settings” or “Message Options” entries, and look for “Message Centre” or “SMS Centre number”. If you’re having problems, try the phone’s instruction book, or look for information online (such as the Nokia and Sony Ericsson websites). If in doubt, contact G-Force Communications Ltd or your mobile phone network provider for help.

How do I find the IMEI serial number of my handset?

The quickest way to find your handsets IMEI serial number is to dial *#06# and have the 15 digit number displayed on screen. Alternatively, the IMEI serial number is usually located on a manufacturer sticker beneath the battery on the inner casing at the rear of the handset.


Is my phone still under warranty?

Every handset supplied as ‘New’ by G-Force Communications Ltd comes complete with a 12 month warranty as standard.

Warranty information for some mobile phones can be found for Nokia mobile phones, by entering the code *#92702689#. This gives serial number, date made, plus editable purchase and repaired dates.


Will my handset work abroad?

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 G-Force Communications Ltd or your mobile phone network provider to ensure that this service is enabled for your phone prior to travelling.
  • 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 the law about mobile phones while driving?

It is illegal to drive a vehicle or ride a motorbike and use a hand held mobile phone or similar device. It is also illegal to supervise a learner and use a hand-held phone. Hands-free phones are also a distraction and you risk prosecution for not having proper control of a vehicle if the police see you driving poorly while using one.

  • A hand held device is something that “is or must be held at some point during the course of making or receiving a call or performing any other interactive communication function.
  • A device “similar” to a mobile phone includes a device that can be used for sending or receiving spoken or written messages, sending or receiving still or moving images or providing Internet access.

If you accept a roadside fixed penalty notice, you will receive 3 points on your licence and a fine of £60. If a case goes to court, in addition to points, you could face discretionary disqualification on top a maximum fine of £1,000 (or £2,500 in the case of drivers of buses / coaches and goods vehicles).
