vodacom 5g

I Bought a Samsung Galaxy Note 20 Ultra 5G from ebay to Do 5G Speedtests on Vodacom South Africa Network... The Problem is when i went to a restaurant "Yumcious" i was with my Mum and she has a Oppo Reno 7 5G and got Over 400 Mbps on Vodacom 5G but on my Note 20 Ultra 5G my Speedtest is 30 Mbps...
