How to Buy a SIM Card in El Paso, USA in 2026
Searches for this page fall into two groups. English readers look for an unlimited data plan in El Paso; Spanish readers, who are most of our visitors here, ask where to buy a phone chip, what one costs and how to get a US number. Both have the same starting point: El Paso sits on the border with Ciudad Juárez, so the first job is making sure your phone is on an American network rather than a Mexican one. This guide covers that, where to buy a SIM at El Paso International Airport (ELP) and in town, and our eSIMs for Texas and the rest of the USA.
Unlimited data in El Paso
We do not sell an unlimited plan for the USA. Our largest US plan is USA 20GB at $27 for 30 days, which covers a month of maps, messaging and social media for most travellers. If you want an unlimited allowance on a local SIM, ask in a carrier store exactly what its prepaid plans include before you pay. If you mainly use maps and messaging, 20 GB is plenty.
Close to the border: watch which network you are on
A report written by someone posted to Ciudad Juárez warned that phones can pick up Mexican networks near the border, even in El Paso, and advised turning off data roaming. The report is from 2016, but the advice still costs nothing: if your phone shows a Mexican network while you are on the US side, choose an American one by hand.
Visitors from Mexico often ask whether their own chip works in El Paso. Telcel's "Sin Frontera" service lets a Telcel line use its plan's minutes, texts and data in the US and Canada, but only if the service is included in the plan and the line has already been used on Telcel's network in Mexico. Without it, Telcel's standard international roaming rates apply. Check your plan before you cross.
Buying a SIM at El Paso International Airport
We found no InMotion or carrier store at ELP. The airport's own list of services mentions a Best Buy kiosk at the entrance to Concourse B, on the upper level, selling small electronics such as earbuds and tablets; it does not mention SIM cards. The terminal closes after the last departure and reopens at 3:00 a.m., so a late arrival leaves you with nowhere to buy one until morning.
Where to buy a chip in El Paso
In town, a prepaid SIM (a "chip" to many Spanish-speaking readers) is sold in two kinds of shop. Carrier stores for AT&T, Verizon and T-Mobile sell their own SIMs and can activate a plan on the spot. Walmart, Target and Best Buy sell prepaid SIM kits from the main networks and from smaller prepaid brands. One guide puts a prepaid SIM at between $10 and $30 before the plan itself.
Bring your passport, as some shops ask for ID and guides disagree on which. Your phone must be unlocked, or an American SIM will not work. A US SIM gives you a US number, which is what people searching for a chip "con lada de Estados Unidos" are after.
UScellular in El Paso
Some readers search for UScellular. T-Mobile bought UScellular's wireless business on 1 August 2025, and UScellular's prepaid service has now ended: the last day to top up was 15 June 2026, and customers were moved to T-Mobile prepaid. UScellular is no longer an option for visitors.
Our eSIMs for El Paso
An eSIM needs no shop and no chip. You install it at home over Wi-Fi, keep your own SIM in the phone, and switch the eSIM on when you arrive. Our USA plans connect to Verizon, AT&T and T-Mobile and start on first use: USA 5GB for $8 (7 days), USA 10GB for $15 (14 days) and USA 20GB for $27 (30 days). The Global PAYG Data eSIM at $20 with €17.50 of credit suits occasional use. UK visitors can take Three Travel 6GB at $19.27 for 30 days, with unlimited calls to UK numbers. The O2 SMS Only eSIM at $8 a month receives texts on a private UK number.
