EE, Orange or T-Mobile U.K. First, you select either black or white, and then the carrier you want. Orange is giving the handset away for free with a £26 ($41 USD) monthly plan that you are locked into for 2 years. You receive 250 minutes of talk, unlimited texts and 750MB of data. For the same monthly price, T-Mobile U.K. gives you the phone with 300 minutes of talk, 500 texts and 1GB of data. Again, a 2-year contract is required.
If you want 4G LTE service, EE is your play. For as low as £31 ($49 USD) a month over 24 months, you will get the BlackBerry Q5 for free. This plan offers unlimited calls and texts along with 500MB of data. For £41 ($64 USD) a month, the data portion of the plan rises to 1GB.
While the three carriers are taking pre-orders for the BlackBerry Q5, no launch date for the phone has been announced.
