eSIM Guide for the USA
Planning to use an eSIM in the USA? Use this guide to check device compatibility, coverage and allowances before choosing a MartX global plan.
Start with destination coverage
For travel across the United States, compare the included networks with your cities and any road-trip stops. Check whether the plan includes calling and SMS as well as mobile data.
MartX currently lists Discover+ global packages. This guide does not represent a separate local-country plan or guarantee that every listed package covers your destination. Confirm coverage for the exact package and ask support if the information is unclear.
A plan with a phone number is different from a data-only plan. Read the call allowance and supported destinations rather than assuming all local calls are included.
What to check before purchasing
- Your phone supports eSIM and is not locked against the networks you need.
- The package includes your destination and enough data for your trip.
- You understand when its validity starts and when it expires.
- Calling, SMS and any included number match your needs; these are separate from data.
- You can access the installation instructions and a reliable connection when setting up.
Choose and install your plan
Browse the global eSIM packages, choose a plan and set the quantity. You can combine eSIMs with gift cards in your cart and review the full cost before payment. After delivery, open My eSIMs in your account for the available installation details.
Keep installation details private and follow the instructions for your device. If activation fails, contact support before deleting the eSIM profile, as reinstalling it may require provider assistance.
