At this point it's ridiculous, the one ui 6 beta should have been available in the UK for ages now yet still no banner, Iphone beta program as so much hassle free
So you want me to ring vodafone and moan about it, like not having the beta ain't a deal breaker or anything just wanted to experience is before switching to iPhone
Unfortunately, network providers like Vodafone add network optimisation software to the phones. So although you can use any SIM card, it's technically not unlocked. Hence your phone is not eligible for the Beta program. But to be honest, you probably won't be waiting too long before it comes out as general release software
