Slow SMHS (tethering) after moving from Galaxy S8+ to S10 same SIM


    I have just purchased a Galaxy S10 model SM-G973U and when trying to tether am getting very slow speeds compared to the S8+ using the exact same SIM card (direct swap back and forth yields the results below).


    I saw some of the other posts regarding 'slow tethering' but this seems a bit more unique since I can go back to my old device (S8+) and everything works great.


    If anyone has any ideas, please let me know.


    Same SIM Card, double checked and same APN settings on both phones.
