I'm considering getting the Honor 5x, which is a dual sim phone. As with most dual sim phones, only one of the sims works on 4G at a time - the inactive one works on 2G.
I plan to have a Koodo talk and text sim paired with a separate data sim. Obviously I would want the data sim to use the 4G when it's in use, but I've heard that Koodo does not work at all on 2G, so my question is: will I still receive messages if the Koodo sim is relagated to 2G? I don't use voice very much, so I don't mind switching to make phone calls, but receiving texts is much more important.
And yes, I know I could just use VOIP on the data sim, but I frequently travel to areas where data reception is spotty, so it's important for me to keep my main number on talk and text.
Here are the frequencies the Honor 5x operates on:
