Speeds are very dependent on a ton of factors right now, so it's not unusual for me to see 50-60 Mbps download speeds during peak times but then jump up to 150-200 Mbps during very low usage times. As has been the case the whole time, speeds continue to increase as the satellite constellation grows. The largest boost in speeds will come once they start using the satellite-to-satellite laser links since ground station congestion can easily be avoided (the biggest bottleneck now).
With T-Mobile adding satellite comms using Starlink, it should be a huge benefit to overlanders!
