Advice on broadband options

Hi to all, Now my university is closed for the duration of the health crisis, I have to give at least 16 hours of tutorials / lectures a week via zoom. The audience varies between 20 and 80 students. As my only internet connections are: 1. is a dongle (with Vodafone) that has 3GB , and 2. my mobile phone with 60GB (also with Vodafone) I am urgently in need of a much better connection. Any advice on what and with whom? I am in rented accommodation in Macleod, pretty much a mobile blackspot, and the landlord doesn't like the idea of cable being brought to the premises. Thanks Joanna -- Stripes Theotoky
