I am somewhat spoilt by the convenience of 4G hotspots with battery. If electricity goes, the internet still works. This is important for financial transactions, otherwise I don't care, I can just fire up the phone's hotspot if my router loses electricity. But I like the convenience a battery-powered hotspot provides when conducting financial transactions. I have had several occasions where electricity went but my transaction did not suffer due to my using 4G hotspot since some years.I regularly get 80-90 mbps DL and 18-20 mbps UL with Jio SIM using TP-Link MR600 with 2CA (3+40 or 5+40 bands). At same location Jiofi gives about 15-20 mbps DL and 2-3 mbps UL
