If BT secures a deal to buy EE, it will acquire the 'number one' mobile service provider in the UK, Olaf Swantee has claimed.
The EE Chief Executive believes his company has played a huge role in the UK's mobile success story, as Britain catches up and overtakes other nations for 4G.
EE - which was formed in 2010 through a merger of Deutsche Telekom and Orange's UK operations - enjoyed a great year in 2014, attracting 5.7 million new customers in just 12 months.
This took the firm's subscriber base to 7.7 million in total.
"It's very much another milestone for us after starting out just a few years ago with the roll-out of 4G," Mr Swantee told the Telegraph.
He claimed the UK was lagging behind the US, South Korea and many other markets, but is now "absolutely on top of the world" in terms of network.
Britain is also leading the way in terms of 4G customer numbers within the European market, Mr Swantee added.
He said there is a "huge appetite" for super-fast, 4G mobile services in the UK, and EE is doing its best to provide a great customer experience.
The ever-rising subscriber numbers suggest that EE - which Ofcom recently confirmed as the fastest mobile broadband provider in the UK - is achieving this goal.
And despite the current uncertainty over the firm's future ownership, in the wake of BT's multi-billion pound bid, it is very much business as usual for EE.
Mr Swantee explained that the BT takeover is in the due diligence process, as part of the negotiation phase. If this is successful, the deal will enter the regulatory stage, where potential competition issues will be considered.
"If you look at the press around why BT has expressed so much interest, it's because of what we have delivered and where we are today," he stated.
BT doesn't currently have any mobile capacity, and EE is the fastest mobile service provider in the UK, with the most extensive 4G network.
"Clearly, if the process comes to a successful closure, and I don't really know when that will be, BT has opted to buy the number one in the UK," Mr Swantee told the news provider.
"We are an industry leader, and not just in the UK. When you look at our position, we are the largest 4G base in Europe."
