The 7in tablet PC, which is smaller than the iPad, and runs version 2.2 of Google's Android operating system, is priced at £529 SIM-free.
Alternatively users can purchase the tablet PC with Talk Mobile's monthly 1GB data subscription, which costs £10 per month on a 30-day rolling contract, for £499. The Carphone Warehouse says the device will be available from November 1.
The Galaxy Tab, which is powered by a 1GHz Samsung Hummingbird ARM-based processor, also benefits from 16GB of built-in memory, Wi-Fi and 3G connectivity and front- and back-facing cameras.
