Few 4G router support voice calls too where one can connect any analogue wired landline or cordless phone for calling using the sim card mobile number. Another useful feature is carrier aggregation or 4G+ which allow the 4G router to access two or more different mobile frequency at same time for better speeds. Currently we have Tp-Link MR600 only that supports 2CA. Hopefully more routers in future will support CA aka 4g+ network for better data speeds.
