Six months after BT pencilled an MVNO agreement with EE – the UK’s largest mobile operator – the fixed-line incumbent announced today that the contract had been signed.

Under the “multi-year agreement” EE will provide “various MVNO” services – on an exclusive basis – to BT’s customers and employees in the UK.

BT previously had an MVNO agreement with Vodafone, targeting business customers. According to press reports, however, the agreement was nullified following Vodafone’s acquisition of Cable & Wireless Worldwide (a fixed-network rival to BT with a string of enterprise customers).

As well continuing to provide mobile services to business customers, BT said it plans to build on its “strong Wi-Fi presence” for consumers through the EE partnership.

BT added it would manage the change from its current UK MVNO provider to EE to ensure a “seamless transition for customers”.

As part of the agreement, BT mobile customers will be able to access 2G, 3G and 4G services.
