Do you need a US phone number when you visit the US?

September 30, 2026 · United States

Most travel eSIMs for the United States give you data and nothing else. That's fine for a week of sightseeing. But the US runs on phone numbers more than most countries: sign-ups, deliveries, appointments and banks all want one, and many will only take a US number.

When data alone is enough

A holiday of a couple of weeks or less.
You talk to friends and family on WhatsApp, iMessage or FaceTime.
You're booking hotels and tours through apps and sites that accept your home number.

In that case, a data eSIM and your home number (with roaming switched off for data) cover you. Our Global Select eSIMs work in the US for exactly this.

When you'll want a US number

Verification codes. Venmo, US bank apps and many sign-up forms only accept a US mobile number, and text a code to it.
Longer stays. Students, interns and people on work trips need a number for landlords, employers, schools and doctors.
Local calls. Calling a restaurant, a hotel desk or a rental car office is simpler, and Americans are more likely to pick up a local number.
Being reachable. Rideshare drivers, couriers and new contacts can call or text you without an app.

Your options

Roam on your home plan

Easiest, and you keep your number, but it's usually the most expensive way to get data and still doesn't give you a US number.

A data-only travel eSIM

Cheap and simple for short trips. No number, so no texts from US services.

A US prepaid line

A real US number with calls, texts and data. You can buy one in a store after you land, or install an eSIM before you leave. Haxzu's United States plan is $19.99 for 30 days: a new US number, unlimited talk and text, unlimited 5G data with 15 GB at full speed, and calls to 90+ countries, on AT&T or T-Mobile.

Also crossing into Canada or Mexico? North America Unlimited covers all three countries with a US number ($50 for 30 days, or $30 for 14).

Keep both numbers

Phones with eSIM run two lines at once. Install the US line for data and local calls, and keep your home SIM switched on so you still get texts from your bank back home. Turn off data roaming on the home line so it doesn't cost you anything for data.

Questions

Can I get a US phone number before I arrive?

Yes. With an eSIM you can buy and install a US line at home and have the number before you fly. Haxzu's United States plan is $19.99 for 30 days with a new US number.

Can I use Google Voice as a visitor?

Not easily. Setting up Google Voice requires an existing US phone number, and it's a VoIP number, which some banks and apps refuse for verification.

Is a travel data eSIM enough for the US?

For a short trip, often yes: maps, messaging and app calls all work over data. It falls short when a US service insists on texting a code to a US number, or when you need people to call you locally.
