Wife's phone has 4G and signal i have not why

[Owen+gumfighter]

On 2 separate occasions in recent weeks we have been too other locations and my wife has had 4G and phone signal. I've been sat 3ft away from her and i have nothing, we're both on sky mobile tariffs. Why is this possible, wife has a Samsung A14 and i have an opppo x3 find lite. Tia.

Have you tried a replacement sim in your phone:

I'm not sure if it is the sim card, my theory is it's the phone itself. I was really happy with my phone (oppo x3 find lite) but in recent weeks I've found it lacking in certain areas.
