4G devices from the US could work here by 2020
Bothered by the lack of 4G mobile gadgets here, or how devices from the United States can't work on 4G networks here? This will likely not be a problem when Singapore starts to use a 700MHz radio frequency for mobile broadband by 2020. Singapore now uses airwaves for 4G that differ from those in the US. So, many devices there cannot work on 4G networks here.
