From begging I could see much lowe network connection from EE in my Samsung but I always through it's because of network issue.
I run bussines and need second SIM card and phone. I purchase Lycamobile SIM card (EE networks) and use my old device Huawei p40pro.
Networks on Huawei it's always full 5g where my Samsung have 2-3 bars...I think SIM card. Faulty. I swap wim.card (Luca to Samsung) same result 2-3 bars where my EE card in Huawei fully 5g.
I restarted Samsung phone like for brand new. I rund diagnostic from phone and show me everything fine. Why Samsung it's bad from network. My miss have s22ultra and a23 ultra also bad network so it's 1000000% problem from Samsung. Anyone make any claim to have any reimbursement money from them? It's not cheap phone. They describe best phone brand in the world
