UPDATE 27/5: NOW IN STOCK.
Further delays have been caused by a last minute change in commercials by Samsung. Stock is now expected late next week approx (28th May). The selling price has also increased as a result. Customers affected by the delay have been notified and the new higher price on the website. The blue colour option has also been removed, with only Black or White available for purchase. Should delays with any particular colour(s) occur next week, then affected customers will be contacted with up to date stock information and their available options. The supply of SIM free stock is ultimately in the hands of Samsung; until next week all official UK Galaxy S5 stock is to be sold directly by them or their chosen partners. Clove’s shipment, along with other online retailers who have been waiting for UK stock, is to be fulfilled by a distribution partner in conjunction with Samsung.
On a slightly more positive note, Android Central have confirmed that the S5 is still subject to a region lock, but they have made it clearer how to remove this.
There is a label on the box that reads:
European Model: This product should be activated with a SIM card issued from a mobile operator within Europe (as defined EU/EEA, Switzerland and the following Non-EEA countries Albania, Andorra, Bosnia and Herzegovina, Former Yugoslav Republic of Macedonia (F.Y.R.O.M), Monaco, Montenegro, San Marino, Serbia and Vatican City.) To use SIM cards from other regions, a cumulative call over five minutes must first be made with the SIM card from European operators.
If you are ordering from Clove to a country outside of the intended region, you will be asked at the checkout to confirm your acceptance of this limitation as well as your consent for the box to be opened and the device activated on your behalf.
