I seem to always have an issue where I can only watch videos at 1080p 30fps or less while on data and if I try to increase the resolution or frame rate it results in the video buffering constantly.
My phone tells me the data speed (in notification bar) and I believe the bandwidth is being capped. This cap does not happen when I use the desktop version in my browser allowing me to effortlessly stream 4k 60fps video without stutter.
Why is this a thing and is there any way to remove the bandwidth cap? I'd like to actually use the data I pay for.
Thanks for using the forums to get this issue with your mobile data services looked into, I am sorry if this has been causing some frustration. I would be more than happy to look into this for you. We do not use caps in the sense that we cap your speed, we do have a spend cap but this is solely for financial protection.
Can I ask what device make and model you have please? I want to see if this is something your handset is doing.
I also think that it could be due to the WIFI channel your handset is using, 2.4ghz is for low usage on mobiles, sending pictures, streaming standard quality videos etc is perfect. But if you're wanting to stream higher quality playback, 5.0ghz may be better. I have a link here that will show you how to change your channels.
Please let me know if this helps and what device you have.
I have also checked our data coverage checker in your area but cannot see any issues with the local masts or signals.
Do you have another handset to test the SIM on? If it works fine then its a good indication that it may be your phone causing the issue. If it still happens on another handset then a SIM replacement may be the way forward.
So I tried putting the SIM in another phone (Samsung galaxy S8) and I've had the same issue where the data speed is fine but when I tried to watch 1080p60 video (no 1440p option) it started buffering a lot which indicated that the slow data speed on YouTube exclusively was not due to my device.
