test alert not received

When I didn't receive the recent test emergency alert, I contacted Fizz and they opened a ticket. Their response was: "To receive the alert, you must be connected at the time of the alert on LTE (not on 3G)." This surprised me because I thought I would be connected to LTE all the time.

I asked the support again for further details but they gave me the same (not very helpful) response.

I have the Galaxy A54 5G. In my network settings, the following option is enabled:

With my previous phone, I always received these alerts. My husband, with another provider, received the test alert. And yes, emergency notifications are enabled on my phone, the sound was on, I was neither in Airplane nor in Do not disturb mode.

At home, I usually don't enable Mobile Data because I use my Home WiFi. But if I turn it on, it shows LTE+. However, when I turn Mobile Data off, I only see the bars but no details about what network I am connected to. I also turned off the phone, took out my SIM card and reinserted it to see if that changed anything.

So I don't really know what else to do to make sure that I am connected to LTE. Any ideas?

    LTE (Long-Term Evolution) is a standard for high-speed wireless communication, primarily used for data transmission. UMTS (Universal Mobile Telecommunications System) is an older 3G technology often used for voice calls. When your phone switches from LTE to UMTS during a call, it's using a different network band better suited for voice communication. Some newer phones and networks support Voice over LTE (VoLTE), which allows voice calls to be made over the LTE network, maintaining high-speed data connectivity even during calls. This seems to be what happens when you have Mobile Data enabled. For users who don't have a mobile data plan or have their mobile data disabled, their phones will typically switch to a 3G network like UMTS for voice calls. This is perfectly normal, but it means they won't have access to high-speed data services during the call. For most users, making calls over UMTS (3G) is sufficient, as it provides reliable voice call quality. However, they might experience slower data speeds if they try to use data services during a call without VoLTE.
