Will I have signal in Big Bend National Park?

Rarely. Big Bend is one of the remotest parks in the country, with almost no coverage across its desert and canyons. Download offline maps, tell someone your plans and treat the park as fully off-grid.

How is coverage in Austin and the big cities?

Excellent. Austin, Dallas, Houston and San Antonio all have strong 5G, so rideshare, live-music tickets, mobile ordering and maps work smoothly, even in busy downtown and festival crowds.

Good to know in Texas

Texas distances are huge - the drive from Austin to Big Bend is over six hours through remote country. Fuel up, download offline maps and carry water, because mobile signal and services both vanish for long stretches out west.

Best time to visit Texas

Spring (March to May) and autumn are mild and pleasant; summers are long and very hot, while Big Bend is best explored in the cooler winter months.

Two simple ways to buy

Texas eSIM plans: unlimited, or by the GB.

Every Texas eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Texas — you can always top up or switch on your next trip.

Traveller streaming and browsing freely on an unlimited-data travel eSIM

Unlimited plans

High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

Best for streaming, video calls & hotspot
Great for longer or open-ended trips
One price per day — no GB anxiety

By-the-GB plans

3GB10GB20GB

A set bundle, brilliant value

A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.

Best value for lighter, shorter trips

Plan your data

How much data do you need in Texas?

A rough, honest guide to sizing your Texas eSIM so you're not guessing. Most travellers in Texas are comfortable on 3–5 GB a week — heavy streamers just go Unlimited.

Texas eSIM: your local data guide.

Texas is vast - Austin's music venues, San Antonio's River Walk and Alamo, Houston's space centre and the remote Big Bend desert on the Rio Grande. A Texas eSIM keeps rideshare, BBQ-joint queues and long-haul highway navigation running, which matters when a single day's drive can cross hundreds of miles of open country.

One eSIM for Texas and all of USA. It's the national USA eSIM — from $3.12/day with unlimited data, working the same in Texas as it does the moment you leave it.

A typical trip runs 5-10 days, often pairing one or two cities like Austin and San Antonio with a Hill Country or Gulf Coast add-on.

How much data for Texas

Balanced 3-5 GB covers city exploring and navigation; opt for Unlimited if you'll stream music on long drives or tether devices during remote road trips.

Coverage in Texas

5G is strong in Dallas, Houston, Austin and San Antonio; coverage thins across the Hill Country and Panhandle and all but disappears in Big Bend's backcountry.
