The Polish government's Safety Guide recently emphasized the importance of avoiding overloaded telephone lines, suggesting the use of SMS instead. But with today's advanced 5G internet, can phone lines still become overwhelmed? Is it mainly voice calls that could cause this issue? Also, wouldn't it make more sense to recommend reducing bandwidth usage—like not streaming videos—during high-demand times?

Definitely! There's still a limit to how much bandwidth we have, even with modern networks. If too many people try to make calls at the same time, it can lead to overload. SMS is designed to handle this better because it uses separate control channels and can hold messages until capacity frees up, but sometimes messages can still get delayed or dropped.
Yes, it happened during the 7/7 bombings in London when everyone tried to call their families at once. There's a specific way to size voice call connections, and if they’re not large enough, overload happens quite easily.
Yes, systems generally aren’t built for 100% usage. If a lot of people are trying to use the lines, it’s easy to reach that limit and overload them. Plus, not all phones handle VoIP calls automatically, which makes matters worse.
Absolutely! Peak times, like when office workers head home, can really clog the cellular networks. You might have to redial a couple of times to get through, that’s for sure.
For sure! Just one phone call can take priority over other data streams, meaning a single voice call can disrupt a lot of other communication. When too many people start calling, it can definitely lead to overload, especially locally and as you move further up the network.
