The Samsung Galaxy S3 will go on sale on 30 May (or the 29 May for some lucky people) and if you are planning on buying the phone then we've rounded-up all the best deals and prices on offers from all the major UK networks.

Samsung Galaxy S3 Release Date

Many smartphones fans have been waiting to upgrade their phone in 2012 until the release of the Galaxy S3, and with it launching next week, getting the best deal to suit you is vital. Whether you want to pay nothing up-front, or want to stick to a lower monthly bill, the UK networks seem to have it covered.

The Samsung Galaxy S3 will feature a 4.8in Super AMOLED screen with a resolution of 720 x 1,280; a quad-core CPU running at 1.5GHz, will come with Android 4.0, has an 8 megapixel camera, and have a Siri-like feature called S Voice.

The 3G version of the Galaxy S3 will be available in Europe on 30 May and will come in 16GB, 32GB and 64GB versions. Only the 16GB and 32GB versions are currently being offered at the moment, with the 16GB version available SIM-free for £499.

All the major networks in the UK will carry the phone, including O2, Vodafone, Three, T-Mobile, and Orange and the phone is also available via Tesco Mobile, Carphone Warehouse and Phones 4u among others.

Here we round-up the deals available from all carriers:

O2

O2 is offering both the 16GB Marble White and the Pebble Blue versions of the Galaxy S3 on 18-month or 24-month contracts with the up-front cost ranging from free to £299.99.
