Which doesn't have end-to-end encryption by default - and no business model?

Actually, I don't get why people would ever recommend Telegram.

I absolutely agree with you. The point I did want to make is that access to other payment methods isn't really easy, either.

Reading your article was a joy for me an I think it will help many people.

Access to Visa & MasterCard isn't what I'd call easy and convenient.

Previously, my perception was that WeChat Pay isn't available for me because WeChat isn't allowed to operate payment services in Europe, thus tries to keep me outside the system.

However, things could be easier since it's prepaid.

I think many people here do that.

Let computers be the tool you use. You don't profit from imaginary "elegance" in parts of the computer that you don't need for your daily work. Be a regular user. Develop only what you're good at.

Think about return on (time) investment. If you take weeks to configure your editor and learn how it works, it's most likely not worth it.

It's okay for software to be intuitive and easy. It's a tool, after all. If there is no proper onboarding and the software doesn't explain itself, the developers didn't get the UX right. You shouldn't rely on them for your work.

Has there been any development that goes beyond masking?

What might me important for some reader: shutting off 2G services means that you won't have telephone voice services, if your operator doesn't support voLTE.

If you question lawful interception, then your problem is not the technical standard that allows it, but your have a problem with society and the laws it implements.

There are good reasons to have security endpoints in the core network instead of the base stations. But it doesn't affect lawful interception at all.

I won't contact you in that matter. I get an idea from what you've said, thank you.

Do you have information on professional detection equipment?

Detection apps are known to be ineffective. It's mostly because IMSI catchers comply with the standard. Your baseband will fall for that - there's not much useful information to be passed to the operating system - or even an app.

What flaws are there, exactly? Missing mutual authentication are the main cause for 2G's security issues. There are no trivial MitM attacks on 3G and 4G - besides denial of service that may result in downgrades. There are location and identity leaks, but that's user tracking at best. Not to compare with 2G.

What am I missing here?

2G doesn't have mutual authentication, thereby Man-in-the-Middle attacks are trivial. From 3G on, attackers cannot simply fake the real network.

Actually 5G provides this overhaul, more than it provides speed benefits for customers.

The 4G backend still has a web of trust between operators and their e.g. IP exchange providers. As far as I know, this will change with 5G.

Roaming data confidentiality can then be routed and encrypted until the home operator network, while the associated metadata is accessible for the IP X to provide their services.

The home operator can verify the smartphone is actually in the visited network.

These are all bits and pieces that break up the operator's web of trust.
