in office or home it’s 100% wifi. and office working sinkies spend more time at these two locations than anywhere else. this is why wifi is the most effective and efficient offloading broadband access for mobile networks. mobile operators should thank their wifi counterparts for saving sextra capacity required to serve everything mobile, instead of complaining about wifi competition. with the cost savings mobile networks should be offering mobile access at lower rates instead of increasing them for “upgrades”. in u.s. that’s sexactly what is happening. competition among not only mobile operators but also with wifi providers (usually cable and fiber operators) spurs innovation, reliability and efficiency and causes prices to cum down. it should be the case in sg but i suppose it’s an oligarchy in sg.
