Any tips on how to get a seamless ISP change?

Last time I just signed up with a new ISP. Change was fast, but I ended up paying for two connections for a month due to notice periods.

My current ISP doesn't require notice, but will charge for the current month in full (up to "billing due date" is their wording).

I'm thinking of setting my new ISP to one day before my billing due date, and having my current connection canceled on the billing due date. Is this a good plan.


For interest I am currently on Gig UFB with 2 degrees, and am planning to change to Vodafone fiber max.


13 months ago I was on Vodafone fiber max, paying $130/month (with $10 on account mobile discount). Currently paying $110/per month (took $300 signing bonus). Vodafone now charges $92.99, with $200 bonus on 12 month term (with $10 mobile discount). I am aware Vodafone's customer service and billing are bad.

Decision is largely driven by price. Also I had found I had a better internet experience on 2 degrees. Most of this is due to my ASUS RT-AC68U topping out at about 500mpbs on 2degrees due to CPU load caused by PPPOE. No such issues on Vodafone. Also have experienced peak time slow down's on 2 degrees that I didn't on Vodafone (Although this seems to have improved lately). Don't plan to upgrade my router again until Wifi 6 is mainstream.
