1Quality of service (QoS): Optimum Mobile leverages T-Mobile 4G LTE and 5G networks to deliver nationwide network coverage. After reaching 20 GB (for Unlimited data plans) or 50 GB (for Unlimited Max data plans) data is reduced to 3G (512 Kbps) speeds for the remainder of the bill cycle. Subject to this QoS policy, video streaming at HD quality (about 1080p), tethering on high speeds (comparable to mobile usage) and after 5 GB of tethered data usage for unlimited and 15 GB for Unlimited Max, then it will be throttled to 512 kbps. Domestic off-net (roaming) at 2G speeds. See our Broadband Disclosure for additional performance and network management details.
