Will changing the SIM improve signal strength? Poor signal strength iphone 11
I have upgraded my phone from 6s to an 11. But the signal strength appears weaker. I use to see 3 or 4 bars now I only see 1 bar. My friend is with the same phone carrier and I swapped SIMs, with his SIM the signal appeared stronger. He has an iphone 12 mini. Does anyone know if changing the SIM will help or does the iphone 11 just have poor reception? Thanks
