What was the percentage increase in wireless service revenue, ARPU, and EBITDA growth compared to the same quarter last year? 
 ahead with our capex acceleration plan building the best broadband infrastructure and remaining comfortably on track to hit our upsized network expansion targets for 2021. We invested another $1.2 billion in new capital this quarter, 12% higher than last year on direct fiber and fixed wireless connections as well as further expanding mobile 5G coverage and deploying 3.5 gigahertz capable radios as we continue to get ready for the launch of true 5G next year.
We leveraged our accelerated broadband network plan, retail channel strength, improved direct sales capabilities and multi-brand strategy to deliver 266,919 total mobile phone, mobile connected device, retail Internet and IPTV net additions in Q3, an increase of 10% over last year. In wireless, our sharp focus on higher-value mobile phone loading continues to pay off.
Based on peers who have already reported Q3 results, we led the Canadian industry once again this quarter in terms of wireless service revenue, ARPU and EBITDA growth. These metrics really matter in terms of providing an indication of the health of our underlying business not just today but also going forward.
As our smartphone customer base grows, roaming rebounds, the decline in data overage reaches an equilibrium point and 5G revenues materialize more meaningfully these levers should continue to support superior future revenue growth and operating profitability. I would also add that we achieved these results against the backdrop of lower wireless prices as we continue to make more lower priced options available that deliver significant value to consumers, and support the government's public policy objectives.
According to the most recent StatCan data pricing for wireless services has declined 25% since September 2019 at a time when overall inflation has been growing rapidly, while the price Canadians pay for all goods and services combined has actually increased 5%. For Bell Wireline, as our broadband fiber footprint advantage keeps expanding, we see the immediate tangible benefits on residential subscriber growth, market share and Internet revenue.
In fact, this past quarter, we delivered the highest number of Internet net adds in 15 years and strong residential Internet revenue growth of 9%. Clearly, the strategy is working. It's the reason why we're so confident in our accelerated capital investment plan. In business wireline, as the team continues to carefully manage near-term COVID financial impacts, which Glen will detail momentarily, our organization is also focused on putting the building blocks in place to ensure Bell is strategically well positioned to capture an industry-leading share of the IoT and next-generation solutions revenue enabled by the convergence of 5G and fiber.
As you know, I have a lot of optimism for the growth potential in this area. There are going to be thousands of applicants and they'll need access to our advanced broadband networks, edge data centers and IoT platforms. We are already leading the way in building momentum with innovative new consumer and business applications that leverage the speed and ultra-low latency of Bell's leading 5G network as certified by PCMag, Ookla and Global Wireless Solutions in their most recent studies of mobile network performance and new MEC alliances with AWS and Google Cloud, which we discussed last quarter.
Recent 5G consumer initiatives include the launch of TSN 5G view and an augmented reality collaboration with TikTok. On the enterprise side of things, we're working with Canadian AI start-up, Tiny Mile, to provide 5G connectivity for its growing food delivery robots in downtown Toronto. We also entered into a partnership with VMware to offer their advanced cloud software, which builds on Bell's agreement with AWS to support 5G innovation and accelerate cloud adoption across Canada.
Notably, Bell is the first Canadian communications provider to offer AWS-powered 5G multi-access edge computing for business and government customers. Most recently, our business markets unit launched smart supply chain powered by Bell IoT Smart Co
