I switched from a 4G plan to 5G plan a few months ago. I was getting 5G speed (>100Mbs) initially after switching. A few days after, the network speed dropped back to 30Mbps and it took a few seconds to load fast.com. I reached out to technical support and they weren’t able to help even added the 5G+ perk and the speed still slow. The agent mentioned there was a 5G promotion plan which was cheaper than my current plan. I made the switch and the speed increased to over 100Mbps in the same location which was previously at 30Mbps. I suspect Koodo/Telus is having some kind of throttling logic which is limiting my data speed. Otherwise, I can’t explain why switching from one 5G plan to another 5G plan would increase the speed.
For other people who is interested in Koodo 5G plans, I got around 30Mbps in Markham/Richmond Hill/Stouffville area on a 5G plan.
