Staying connected in Las Vegas is essential for maps, rideshare apps, hotel check-ins, tickets, and sharing your trip. The cheapest way to get lots of data is usually a U.S. prepaid plan (SIM or eSIM) from a value carrier (Visible, Metro, US Mobile, etc.). For ultra-short trips, a travel eSIM can be faster to set up.
