How to Buy a SIM Card in Las Vegas, USA in 2026
Las Vegas is an easy city to get online in: Harry Reid International Airport has free Wi-Fi, AT&T, Verizon and T-Mobile all sell prepaid SIMs, and Walmart and Target stock them too. The question is what you pay. Airport kiosks charge more than shops in town, and US carrier plans are sold by the month, so a long weekend on the Strip can cost the same as a month at home. This guide compares buying at the airport, buying off the Strip and installing an eSIM before you travel, with the plans we sell for Las Vegas and the rest of the USA. They are on our USA eSIM page.
First minutes at Harry Reid
When you land, connect to the free airport Wi-Fi, LAS-WIFI. It is enough to message whoever is meeting you, book a ride or check your hotel's check-in time, so you do not need to buy anything at the airport in a hurry.
If you do want a SIM there, AT&T, Verizon and T-Mobile prepaid SIMs are sold at airport kiosks and retail stores. Expect to pay more than in town: every source we read says the airport is the dearer option.
Cheaper SIMs off the Strip
Outside the airport you can buy a prepaid SIM in the carriers' own stores, in shopping centres and supermarkets, and at big-box retailers. One guide says a Walmart or Target away from the Strip will undercut the airport significantly. Some retailers may ask for a ZIP code or basic ID, but buying prepaid is far simpler than signing a contract, and you do not need a Social Security number.
Before you buy, know what you are signing up for:
- Carrier prepaid plans run for a month. A short prepaid plan usually comes to about $30 to $65 after tax, even if you are in town for three nights.
- Your phone must be unlocked to take a US SIM.
- Some guides still list Sprint as an option. Sprint is now part of T-Mobile, so ignore that advice.
Which network for Las Vegas?
The USA has three national networks, Verizon, AT&T and T-Mobile, and all three sell prepaid in Las Vegas. Budget brands such as Mint Mobile and Lycamobile use T-Mobile's network and are usually cheaper, but they are monthly as well. If you are planning a day trip out of the city to Hoover Dam or the Grand Canyon, ask in the store about coverage on your route, as we could not find a reliable source on signal outside Las Vegas.
Our eSIMs for Las Vegas
Our USA plans are priced by trip length, not by the month. They run on Verizon, AT&T and T-Mobile, include 5G where available and hotspot, and start when you first use them:
Install it at home and it connects as you walk off the plane, so the kiosk queue and the store visit both disappear. Hotspot lets you share data with a laptop or a friend's phone. Your phone needs to be unlocked and eSIM-compatible.
If Las Vegas is part of a longer trip, Vodafone Travel ($26.60 for 25 GB over 30 days from purchase, UK number with unlimited local calls) and Orange World 20GB ($28, 30 days from first use, French number) also cover the USA and many other countries. For bank texts, O2 SMS Only gives you a UK number for $8 a month.
Las Vegas options compared

| Prepaid SIM at the airport | Above city prices | A month | A local number in a hurry |
| Prepaid SIM at Walmart or Target | About $30 to $65 after tax for a plan | A month | Long stays, a US number |
| USA 5GB | $8 | 7 days | A long weekend |

Our recommendation
For a few nights on the Strip, USA 5GB at $8 is the simplest and cheapest way to stay online, and it works from the moment you land. If you are adding a drive to Hoover Dam, the Grand Canyon or on to another state, take USA 10GB, and for a month USA 20GB. A carrier SIM from Walmart or Target only pays off if you are staying for weeks and want a US number. For the rest of the country, see our USA SIM card guide. Our eSIM installation guide takes you through set-up, and all our plans are on the USA eSIM page.
