It seems that the SNR issue does affect all operators, some more than others. Mobilink LTE in one spot gives this result.
Moving barely 2 steps away from there, the speed drops to 4 Mbps and refuses to go higher.
Very annoying because I don't hang off the side of my balcony all day so it's a bit inconvenient to have to do that to get the right speed.
I complained about this using their heartbeat app and it took my coordinates as well, so I hope something happens about it.
