Wi-Fi needed short term in rental property

[haribosarebest]

Any advice as to what is the best option to get Wi-Fi in a short term rental please. Selling house and moving into rental for 3-4 months until new house ready. Will be in current house and have rental flat overlapping for about a month.
How does a dongle work? Is this a good option? I really am clueless. Can I just switch with my current provider? Obviously don’t want to sign a new contract with anyone as only there for a short period

A dongle uses a mobile phone network, so will be as good as the signal and that networks capacity

Consider it like enabling a hot spot on your phone then tethering laptops to the hot spot.

Had Similar situation and used current provider just notified them of change of address. I do remember many phone calls and a few days without Wi-Fi as they did whatever they have to do to switch/send equipment. In the meantime we were able to hotspot off our mobiles which depending on your phone contract could be a good option.

You need a wifi router with a sim slot and a PAYG data only sim. You can probably get a router off ebay, then sell it on when you don't need it. Much easier than tethering.
