Hi all, I looked up online some info on switching from ATT to Verizon (I'm sick of ATT in NYC... so many dead spots and horrible speed). Will my iPhone X which I bought with ATT be thoroughly useable on the Verizon network? Is there anyone else that made this move? Online research says that I would not be able to use the 3G network on Verizon with my iPhone X (ATT model). Is this a problematic limitation for those that have made this switch? Thanks.
