1. 150Mbps is network specification for downlink of 4G LTE network (2600MHz – CAT 4), with 50Mbps for uplink. However, the actual speed that customer experience will be considerably less than the network specifications and will be affected by customer’s device, transmission technology, individual network and software used, network configuration, coverage, usage level, International bandwidth and other extraneous factors.
