eSIM Travel Tips for Texas
Texas is a major US destination for Australians on American road trips
Texas draws Australians visiting the American South and Southwest, often as part of a larger US road trip. American Airlines operates many Texas routes and Qantas codeshares into DFW. Activate your HelloRoam US eSIM at home before departure. One plan covers all four Texas cities and all of the United States.
Download offline maps before West Texas and Big Bend road trips
West Texas and Big Bend National Park have very limited mobile signal. The Panther Junction Visitor Centre has weak and intermittent signal. Terlingua and Study Butte outside the park have some 4G. Download detailed offline maps and park information before entering Big Bend. The remote landscape requires planning ahead as mobile coverage cannot be relied upon.
Texas interstate highways have consistent 4G between cities
The main Texas highway corridors including I-35 from Austin to Dallas, I-10 from San Antonio to El Paso, and I-45 from Dallas to Houston all have consistent 4G coverage. Small towns along the routes have 4G. Open ranch land between towns can have signal gaps of 10 to 30 minutes driving. Download offline maps as backup for any Texas road trip.
Book South by Southwest and Austin City Limits venues in advance
South by Southwest (SXSW) in March and Austin City Limits Music Festival in October both draw over 200,000 visitors to Austin. Network congestion during peak festival periods on 6th Street and at main venues can slow data speeds considerably. Download schedules, venue maps, and rideshare apps before heading out each day during festivals.
Check Smartraveller before visiting the United States
The United States has standard travel information for Australian visitors. Review smartraveller.gov.au before your trip. Your HelloRoam eSIM keeps you connected throughout Texas and all of the US.
Mobile networks in Texas: T-Mobile, AT&T, and Verizon
Texas is served by T-Mobile, AT&T, and Verizon on 5G and 4G LTE networks. T-Mobile has the most comprehensive Texas coverage overall including the best rural reach and the widest 5G footprint. AT&T is headquartered in Dallas and has excellent coverage across the DFW Metroplex and Houston. Verizon provides strong urban 5G in major Texas metro areas. Texas is a vast state and coverage drops significantly in West Texas, the Trans-Pecos, and remote ranch land. Your HelloRoam eSIM connects to the strongest available US network for the best Texas coverage.

Best time to visit Texas from Australia
March to May and October to November are the best times to visit Texas. Spring from March to May brings mild temperatures of 18 to 28 degrees, bluebonnet wildflower season along Texas highways in April, and the South by Southwest festival in Austin in March. Autumn from October to November has similarly comfortable temperatures with the State Fair of Texas in Dallas in October and Austin City Limits Music Festival. Summer in Texas is genuinely hot with Dallas and San Antonio regularly reaching 37 to 40 degrees in July and August. Houston combines heat with extreme humidity. Winter from December to February is mild in most of Texas at 6 to 14 degrees in Dallas and Austin. Snowstorms are rare but can be severe when they occur in North Texas. Australian school holidays in April and September to October align well with Texas's best seasons.

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!!
Rated 5 out of 5 by this reviewer
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.
