Data for iPhone 12 in the United Kingdom (UK)

We will be traveling to the UK in November/December for 2 weeks (2022). What is the best option for data on my iPhone 12 Pro?
I currently have switched my sim to an eSim so I have the sim tray available.
Google Fi, Orange sim card, etc.

T-Mobile has free data there. We are on Magenta and it worked great for the 10 days we were in the UK.
