GRID - FIRST IN THE WORLD, ONE PHONE, ONE SIM CARD, TWO NETWORKS
A first in the world – with one single handset, one Dual Profile SIM card, you could access two different networks and 3 different services; GRID’s islandwide walkie-talkie services, GRID mobile services and GSM services.

Business Continuity Planning, alternative communications services for emergency responses – the buzzwords that have been used since September 11, 2001, will finally see some viable solution- one that is developed by GRID Communications Pte Ltd (GRID) in conjuction with SingTel. The requirement is simple: have a single mobile device that is linked to 2 independent communication networks so that the user can switch to the other network when congestion happened during crisis.

The Dual Profile SIM The Dual Profile SIM is a combination of a 2G GSM SIM + iDEN SIM which works on normal GRID phone, GSM phone and the Motorola dual-mode smartphone – i930. The Dual Profile SIM card contains 2 subscriber profiles – a GRID profile on GRID’s network and a GSM profile via SingTel Mobile’s network.

More about i930

"One of our handset models, i930, which runs on Microsoft's Windows Mobile , using a dual Profile SIM card. This means that a customer can switch between GRID (iDEN Push-to-Talk network) and Singtel (GSM network) using the same SIM card on i930.

GRID is the first iDEN operator to develop the dual Profile SIM card. We are initially, targeting government agencies who require GRID's Push-to-Talk service during their operational events especially during crisis or emergencies. At the same time, they'd like to use GSM network during normal situations." - Mohamad Taha B. Osman Manager, Wireless Data Business Development GRID Communications Pte Ltd
