Why no 5g?

I am in strong signal area for both Vodaphone and Three, two masts at the end of my road.
Three sim gave me 5g icon, Lebara shows 4g. Never yet seen 5g on phone now it has Lebara?

Check with Lebara support that 5g is enabled

"If you're experiencing issues with 5G signal on your Lebara phone, there are a few steps you can take to resolve this. First, ensure that you have a 5G-enabled device and are in an area with 5G coverage. You can check the coverage in your area using the Vodafone network status checker. If you have a SIM-only plan from Lebara, 5G should come as standard. However, if you need to activate 5G, you can text "5G" to 38885 to receive a confirmation SMS. If these steps do not resolve the issue, contacting Lebara support for further assistance would be advisable. You can find more details about 5G on our website."
Text reply says "Keyword you have entered is not valid"? So don't bother following this advice.

"So sorry to inform you, Bur there is nothing wrong with the SIM and your handset, Just because we are completely depend on the Vodafone's network and since vodafone is struggling over here(NG24###) to provide 5G intensity network. Hence, you and many of our customer are not able to use 5G network."
Also confirmed they only use Voda and not Three.
I will monitor signal elsewhere.
