Three says it will hold back its launch of 4G mobile broadband services until later in 2013.
The firm - one of five winning bidders in Ofcom's recent 800MHz and 2.6GHz spectrum auction - wants to see how its rivals will position long-term evolution (LTE) services before committing to a rollout strategy.
Dave Dyson, Three's Chief Executive Officer, said his company is particularly interested to see how O2 and Vodafone introduce 4G mobile broadband services.
"We’re in no rush to launch LTE," he stated. "I’m fairly relaxed about it."
Mr Dyson said one of the reasons for this is the excellent feedback Three has received on its existing HSPA+ services - a fast version of 3G connectivity.
He noted that the immediate goal for his firm is raising awareness of super-fast mobile broadband.
Mr Dyson claimed it will take time to build customer understanding of 4G services, and convince them of the benefits of upgrading to faster speeds.
Earlier this week, Three's mobile broadband rival O2 claimed that the launch of super-fast mobile broadband will help make 'Digital Britain' a reality.
Derek McManus, Chief Operating Officer at O2, said that by investing in the 800MHz spectrum, the firm would be able to deliver widespread coverage to its customers.
"In fact, because of our network investments, by the end of 2015 we are aiming for indoor 4G coverage that will reach 98 per cent of the UK," he stated.
"And we’re using the opportunity to upgrade our entire network, so even customers who stay on our 3G network will see a significant improvement in coverage."
