Brand new SimFree Nokia, Samsung and Motorola Mobile phones
SM FREE:
SIM Free refers to GSM Phones that are sold without a connection or line. All our SIM Free phones have never been locked to a particular network. It can be said that they are 'unlocked' but they have never been locked to begin with! This is better as it means that the phones are in factory condition and are less likely to develop problems. They can therefore accept any SIM that is associated with a compatable frequency. A tri-band SIM Free phone will work on any GSM network in the world, but you must insert a SIM that works in the area you want to use it. All GSM 900 / GSM 1800 compatable SIM Free phones will work on any SIM.
Mobile Phone
Any Portable Handset for use in telecommunication such as voice and data and increasingly multi-media. This is the same as a Cellular or Cell Phone / telephone.
All of the mobile phones sold by us are GSM phones that use a digital system, often refered to as 2G (Second Generation). With the advent of GPRS (2.5G) a step closer has been taken towards the third generation of mobile phone (3G)
GSM
The most important aspect of GSM is its standardisation. This allows a SIM card owner to insert the SIM into any SIM Free GSM phone (with compatable frequencies) and the phone would work. This standardisation also applies to anywhere one goes with a GSM network. This is provided that the correct frequency of the card / network is available to that handset.
GSM frequencies are:
GSM 900 (O2, Vodafone and most networks around the world)
GSM 1800 (Orange, T-Mobile and some European networks)
GSM 1900 (Used in USA & Canada)
MMS - Multimedia Messaging
With Multimedia Messaging (MMS) you can add far more content than just text to your messages. You can have colourful images, animations, formatted text and recorded sound clips. Multimedia messages are sent over the mobile internet using WAP. MMS requires your network operator to provide this service.
