Best sim only deal for eu roaming

[Stevemr]

Any suggestions welcomed for sim only deals that allow roaming in eu and Switzerland, if you are going for 12 weeks at a time.
Most seem to have a fair use cap of 2 months in 4.

Not used it but had it recommended on here (as long as your phone can use an e-sim)
