Easy and better way to use mobile internet as home network

hi guys,

ive looked for this a lot, and i found a lot of people with the same problem:

Since mobile internet is getting really fast and very cheap, we need a simple way to connect your phone's data plan to your home network.

Example:

I live in a villa on an island in Greece, and my unlimited 4G plan is MUCH faster then my cable connection.

Im talking 80mbps vs 20mbps (real speeds, not as advertised).

5G is coming, so the difference will be even more.

Because of the geological difficulties of Greece (lots of islands) and whatever other reasons, viber will never be an option.

So its mobile data that is the future.

This was also predicted many years ago by analists, so its not that this is a big surprise :)

What we need:

A very, very simple sollution where you can connect your mobile phone to your home network.

Im talking about clicking your phone in a dock, maybe installing an app, and it just works.

All while still using your phone the usual way (so i can still use Whatsapp, GSM calling, SMS etc...)

There are modems and routers with Sim slots, but then you cant use your phone for communication.

You can tether your mobile phone with a router, but its pretty complicated for newbees.

You can make a hotspot, but its not really fast and no way to cover the whole house for my family (inc 4K TVs)

Another solution would be a mobile phone with network and external antennas, but that is getting a bit wierd.

Almost like building an android phone into a router/modem. Sort of 'the-new-old-phone-from-yesteryear'.

if anybody has a sollution for me, please let me know!
