Speed in Europe on partner networks (at least in Germany, Netherlands and Belgium) is downgraded from 5G to LTE, due to partner agreements not optimized yet. (as tested on business trips April 2024 and June/July 2024). This has finally been disclosed to me by Videotron customer service after several support calls. I've done side-by-side tests with my colleagues on the same major networks (T-Mobile, O2, Vodaphone) who have SIM cards from those providers and they are getting 5G and I'm consistently getting only LTE. I've even done this comparison test inside the cell phone providers stores. To my knowledge, only in France, does Videotron have the agreement for 5G. When I was originally considering the Videotron Canada-International plan, none of the sales literature or fine print discloses this fact. Videotron customer service advised me they are working on getting 5G from the partner networks, but would not provide me a time-line of when it would happen, nor would they agree to pro-actively inform me of the progress.
