Hi everyone. Can anyone help with this one? I have 2 Phones. A s21 5g and a s23 ultra. I am on vodafone unlimited data. The s23 reaches a speed test of over 300mbps download and 30mpbs upload speed. The s21 struggles to reach 5mpbs download at best with a slightly higher upload. If I swap the sims over, the s21 is 300mpbs and the s23 5mpbs. The 2 sims are both on unlimited uncapped so I'm stumped. I thought the s21 was at fault but it's clearly the sim which was replaced for a new one incase it was that but noooooo. Has anyone any ideas as I can't seem to sort it. Vodafone says the sim is fine....Many thanks
