What Apps Do You Need in the USA? Maps, Uber, Lyft, OMNY, Bookings and Messaging

What apps do you need in the USA? Thai visitors should have Google Maps or Apple Maps for navigation, Uber or Lyft for rides, a transit app such as Transit plus OMNY in New York, Yelp for restaurants, and WhatsApp or LINE to keep in touch with people back home.

Which apps should a visitor install before flying to the USA?

Install and sign in to your apps before you fly, because some send verification codes by SMS and accounts are easier to set up while you are still on home Wi-Fi.

Some ride-hailing apps ask for identity or phone verification at sign-up, so register Uber and Lyft at home, add a card that works abroad, and make sure the name on the card matches the account. Both main map apps are free and offer a Thai-language interface.

Which apps handle rides and subway fares in New York?

In New York, Uber and Lyft are the main ride-hailing apps, while the subway and buses use OMNY, where you tap a contactless bank card, a phone wallet or an OMNY card, according to the Metropolitan Transportation Authority (MTA).

• MetroCard sales ended on 31 December 2025, so use OMNY instead
• Citymapper and Transit show real-time arrivals and transfers
• Tap the same card or phone each time so the system tracks fares correctly

How do you find restaurants and book a table in the USA?

Use Yelp or Google Maps reviews to check ratings and photos, then book through OpenTable or Resy. Popular restaurants in big cities such as New York and Los Angeles often need a reservation in advance, and some ask for a phone number or email to confirm.

• Enter your Thai number with the +66 country code when booking, or use email if the app allows it
• Keep the confirmation email or a screenshot on your phone in case the restaurant asks
• Tipping is customary in US restaurants, so expect it on the bill

Which transit and delivery apps work outside New York?

Other cities such as Los Angeles, San Francisco and Seattle run their own transit systems, but the Transit app and Google Maps show schedules and routes in many of them. Food delivery usually goes through DoorDash or Uber Eats.

Can visitors use Venmo, Zelle and Apple Pay?

Venmo and Zelle are tied to a US bank account and a US phone number, so most visitors cannot use them. The practical option is Apple Pay or Google Pay linked to a Thai credit card, since many shops accept contactless payment.

• Set up Apple Pay or Google Pay and add your card at home, not after landing
• Tell your card issuer you will spend abroad so the card is not blocked
• Carry the physical card as a backup, since some terminals do not accept phone taps
• Set a screen lock and turn on Find My or Find My Device, in case the phone is lost while your cards are in its wallet

What do Americans use to message, and do you need a US number?

Americans mainly use SMS and iMessage, WhatsApp is less common than in Asia, and LINE is barely used, so keep LINE for Thai contacts and use WhatsApp or iMessage with others.

• US numbers start with +1 and have 10 digits
• Data-only eSIMs have no US number, so they cannot receive SMS from US services
• Keep the Thai SIM active for Thai bank OTPs, with data roaming switched off on it

How much data do these apps use, and why does internet matter?

Maps, ride-hailing and messaging use modest data but run all day, and live maps and video calls use the most. Mobile internet from the moment you land lets you book a ride, open tickets and share your location with family at once.

• Download offline areas in Google Maps before entering a national park
• Use hotel Wi-Fi to update apps and download maps before relying on mobile data outside
• Set the phone clock to automatic, because the USA has several time zones
