Those 4G sticks you linked are all USB sticks, meaning you'll only have the home internet on the one device in which you plug it in. If you only have one device (e.g. a computer), that's fine.
If you want to use that 4G connection on several devices, however, you'll need a proper LTE-capable router. In that router, you'll have to insert a special SIM card. If you order a LTE flat at your ISP, they should give you the option to only get the SIM card without a device to use it in, and you'll insert that SIM card into your router.
Unless, of course, your ISP offers a 4G-capable router (not stick!). Then you can use/order that one if you want.
Here's a list of 4G-capable routers I'd recommend, though I can't say anything about availability in your country:
1. AVM Fritz!Box 6810, 6820, 6840 or 6842 LTE, depending on your needs and budget, are the ones I'd recommend most.
2. TP-Link TL-MR6400 or TL-MR3220 (latter is low budget and not that recommendable)
3. Zyxel LTE3301 or SBG3600-N (good, but rather expensive)
If you need more detailed information, feel free to ask.
