USA TRAVEL • DATA ROAMING
USA eSIM vs Your Home Carrier's International Roaming
Before you land in the United States, it's worth comparing what your own network charges for roaming against a dedicated USA travel eSIM - the difference usually comes down to cost per GB, whether there's a daily cap, and how easy it is to set up before you fly.
| Factor | Home-carrier roaming | eTravelSim USA eSIM |
|---|---|---|
| Typical cost for a 7-10 day trip | Many home carriers charge a flat daily roaming fee (commonly $10 or more per day) on top of your regular plan | From $13 for a 10 GB / 15-day plan, or $3.50 for a light 1 GB / 30-day plan |
| Data allowance | Often capped or slowed down once you cross your home plan's roaming data limit | Choose from 1 GB up to Unlimited (Unlimited plans include 4 GB of high-speed data per day, then continue at 1 Mbps) |
| Setup before you travel | Usually needs a roaming add-on enabled with your home carrier in advance | eSIM delivered by email instantly after purchase; activates automatically once installed |
| Network in the US | Depends on whichever local partner your home carrier has a roaming agreement with | Runs on the AT&T network (5G / LTE) |
| Hotspot / tethering | Often restricted or charged separately by home carriers while roaming | Supported on limited-data plans (not available on the Unlimited plans) |
| Calls and a US number | You keep your home number, but incoming/outgoing calls while roaming are often charged per minute | Data + calls plans include a US (+1) number, free incoming calls and unlimited outgoing calls within the USA |
| Paperwork | None - it's your existing plan | None - no ID or documents required to activate |

USA eSIM questions
Does the USA eSIM work with my existing phone number?
Yes. The eSIM runs alongside your physical SIM, so you keep your home number for calls and OTPs while the eSIM handles your US data (and, on call-enabled plans, gives you a separate US number too).
Which network does the USA eSIM use?
It runs on the AT&T network in the USA, with 5G and LTE speeds depending on your device and location.
Can I use my hotspot with this eSIM?
Hotspot and tethering are supported on the limited-data plans (1 GB up to 50 GB). The Unlimited Data plans do not include hotspot support.
What happens if I use all my high-speed data on an Unlimited plan?
Unlimited Data plans include 4 GB of high-speed data per day. After that, speed drops to 1 Mbps until the daily allowance resets 24 hours later.
Do I need to submit any documents to activate?
No. The eSIM activates automatically once installed, with no ID or documentation required.
How is a USA eSIM different from paying for my home carrier's roaming?
Roaming charges are set by your home carrier and often come with a daily fee, a data cap, or per-minute call charges once you land. A USA eSIM is a separate prepaid data (or data-plus-calls) plan bought upfront, so the cost and data allowance are fixed and known before you travel.
