United States travel data eSIM
What is a United States eSIM?
A United States eSIM gives you mobile data for your trip across the 50 states and Washington, D.C. Whether you are exploring the contiguous states or visiting Alaska and Hawaii, this data-only plan connects you to major local networks. It installs via QR code before you fly, so you are ready to navigate cities, national parks, or remote areas immediately upon arrival without swapping physical SIM cards.
Your plan connects to AT&T 5G and Verizon 5G networks. Depending on your specific location, the device links to the available operator infrastructure. This setup supports everyday tasks like mapping, messaging, and browsing while you move between different regions. The data allowance resets or expires according to the specific duration selected, ensuring you have connectivity for the length of your stay.

Local networks
Which networks you connect to in United States
The eSIM connects to AT&T 5G and Verizon 5G networks within the United States. Coverage availability depends entirely on the specific operator network present at your exact location. Urban centers and major highways typically have strong infrastructure, while remote wilderness areas may vary. Your device will link to whichever network is accessible at that moment, ensuring continuous data access for navigation and communication.

Questions people actually ask
If yours is not here, write to us — we answer within 24 hours.
Which networks does the United States eSIM use?
It connects to AT&T 5G and Verizon 5G. This means your device accesses the infrastructure of these two major carriers. Depending on your location, it links to the available network, providing data access for navigation and communication throughout your trip.
Does this eSIM work in Canada or Mexico?
No, this is a single-country plan valid only in the United States. It does not function in neighboring Canada or Mexico. For trips spanning multiple countries, look for specific regional plans designed for multi-country travel to ensure continuous connectivity.
Which plan size suits a trip to New York and Los Angeles?
As a rough guide, the 5GB or 10GB options often suit a two-city itinerary. This depends on how frequently you use maps, streaming, or social media. Heavier usage in urban areas might require the larger data allowance to avoid running out.
Will I lose my own phone number?
No. Your physical SIM stays in the phone and keeps your number for calls and WhatsApp. The eSIM only carries data, so both work side by side.
When does my plan start counting down?
When the eSIM first connects to a network at your destination — not when you buy it. So you can install it days before you fly without losing any time.
Is my phone compatible?
Most phones from 2018 onwards are: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later. Your phone also has to be carrier-unlocked. Dial *#06# — if an EID appears, you have eSIM. Full list on our Device Compatibility page.
How fast will I get my QR code?
Usually within a couple of minutes of payment, by email. If it has not arrived, check spam first, then write to us and we will resend it immediately.
Can I use hotspot or tethering?
Yes, on every plan we sell. Share the connection with a laptop, a tablet or the rest of your group.
What if I change my mind?
If you have not installed the eSIM, you get a full refund within 180 days. Once a profile is activated and data has been used it cannot be refunded — the allowance is consumed from the network. Full detail in our Refund Policy.
Do you sell plans for groups?
Yes. For Umrah and Hajj groups, student trips and tour operators we deliver the QR codes as a single batch before departure, at group rates. Email us with your group size and destination.
