eSIM Travel Tips for USA
Time zones across the US
The continental US spans four time zones. Los Angeles is 3 hours behind New York. Plan video calls back to Australia carefully. Sydney is typically 15 to 17 hours ahead of Los Angeles depending on daylight saving in both countries. A midday call from LA reaches Sydney the next morning.
Coverage in national parks
Grand Canyon, Yellowstone, Yosemite, and Zion National Park all have limited or no mobile signal in large sections. Download offline maps and book campsites before you arrive. Cell signal returns near park visitor centres and gateway towns.
The interstate highway system
Major US interstates are well covered by all three carriers. Rural stretches of Route 66, the Pacific Coast Highway through Big Sur, and parts of Nevada and Montana can have gaps. Download offline maps for any long drives away from the urban corridor.
Keep your Aussie SIM for home contacts
On a dual SIM phone, leave your Australian SIM active for calls and texts from family or your bank. Set HelloRoam as the data line. You stay reachable on your usual Australian number while using local US data speeds.
US culture and tipping
Tipping 18 to 20 percent at restaurants is standard in the US. Card and phone payments work almost everywhere, and Google Maps is your best friend in cities without a clear public transport system. Having data live when you land saves a lot of stress at busy airports.
US mobile networks: T-Mobile, Verizon, and AT&T
The US has three major carriers: T-Mobile, Verizon, and AT&T. All three run nationwide 5G alongside deep 4G LTE networks, covering the big cities, interstates, and tourist regions Australians visit most. Even Alaska is covered, with AT&T and Verizon serving Anchorage, Fairbanks, and Juneau. Your HelloRoam eSIM uses Verizon and AT&T, so speeds depend on their coverage where you are.

HelloRoam eSIM vs Telstra and Optus roaming in the US
Real costs for Australians taking their mobile to America.
| Category | HelloRoam eSIM Recommended | US SIM card | Telco roaming (Telstra, Optus) |
|---|---|---|---|
| Typical cost | From A$4.07 total | A$21.29–A$85.18 total | $5–$10/day |
| Details | Plans start at A$4.07. Buy online, scan a QR code at home, and arrive in Los Angeles or New York already on 4G or 5G. No airport SIM hunt and no bill shock when you get home. | US carriers like T-Mobile and AT&T sell prepaid SIMs at airports and retail stores but setup takes time. Your Australian SIM needs to come out and be stored safely for the trip. | Telstra's International Day Pass in the US charges you for every day you use data. Over a three-week US trip, those daily charges add up fast just for data, on top of your usual Telstra bill back home. |
Prices approximate as of . Actual savings vary.
Best time to visit the United States from Australia
The US is a year-round destination because of its size and varied climate. Spring (March to May) and autumn (September to November) offer comfortable weather in most regions. Summer is hot and busy, especially at national parks and beach destinations. New York winters are cold but manageable. Australians visiting for ski season should target December to March for Colorado, Utah, or Lake Tahoe resorts.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!

Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.

Does my Australian phone work in the US?
Yes, your Australian phone works in the US on international roaming, but Telstra's International Day Pass charges you for every day you use it. A HelloRoam eSIM costs far less and uses the Verizon and AT&T networks, with no daily charge. iPhone XS and newer support eSIM, including the iPhone SE 2020 and later. On Android, most Samsung Galaxy S20 and newer models support it (not the S20 FE or S21 FE), as do Google Pixel 4 and newer phones. Many budget and mid-range Android phones have no eSIM. Check your settings for an Add eSIM option to confirm your device is compatible.

How much does a HelloRoam eSIM for the US cost?
Plans for the US start at A$4.07, with the price depending on data size and duration. For a longer trip covering multiple states, a larger data plan is worth it given how data-heavy US travel can be with GPS running on long drives. Either way it costs far less than carrier roaming, with no surprise charges on your home bill.
Is there mobile coverage in US national parks?
Major park visitor centres and gateway towns have reasonable 4G coverage. Deep sections of Grand Canyon, Yellowstone, and Yosemite have very limited or no signal. Download offline maps and campsite bookings before entering park boundaries.
How much data do I need for three weeks in the US?
Three weeks across multiple US cities and national parks typically needs 6 to 12 GB depending on your usage. Long drives with constant GPS navigation and music streaming will use more. Choose a 10 GB or larger plan for a coast-to-coast road trip.
