I presume you mean in a 5G modem/router?

Yes you can if the device is unlocked for use on any network and you configure the APN settings correctly.

Yes if it's a 5G router.

If it's a 4G router then you'll get 4G/LTE connectivity/speeds. 

If you need to contact 48 support about this then see the links in my signature below.

I tried today from my phone the speed is automatically coming down after Hotspot so when I turned off the hotspot the speed is automatically coming back

So I am going to buy 5g modem so will I consider the same 48 or to change

I don't understand what this means:
