My ISP blanket blocks all VPN's

Hi all
My new ISP blanket blocks VPN’s. Is there a simple way to get around this? I am UK based and use IpVanish.
I know that if I connect my firecube to a different network initially and activate my VPN, then connect to the new ISP, it stays connected without issue.
Ordinarily I would hotspot from my mobile (cell) phone for this initial part but that is also on the same network that blanket blocks. Although IpVanish does work on my mobile.
Is there another way to sort this without changing my mobile phone provider?
Thanks

It’s time to jump ship and move to someone that won’t hamper your VPN. Don’t tolerate that nonsense. There are very valid security reasons for using one and they should not stop you.

worst case you might try a dedicated ip vpn to circumvent the block? just an option that comes to mind.
