dual sim cards?

So, I picked up my unlocked galaxy s23+ tonight and found out it has no sim card. That makes sense since I've learned I have to get one from my provider (Verizon)  I saw a website description that mentions dual cards to speed things up, but couldn't find that in the actual site. Other sites talk about using dual sim cards for second phone numbers. I have no need for that. If two cards could speed data up, I'd be interested, but if not, I'd have no interest in that feature. Anybody here know anything about that?

Not me..sorry..

Don't waste your time unless you have an absolute administrative need. It will use more battery, diminish life-span of battery, can cause internal conflict, etc.

Sounds like just another scam to get more of your money.

Great way for having 2 phone numbers and all that comes with that. Otherwise just another potential problem.
