One eSIM for the whole trip — from New York's subway to the open roads of the national parks.
Data-only plan on T-Mobile and Verizon 5G/4G networks. Starts when you first connect in United States.
Activate within 1 month of purchase
We recommend activating your eSIM no later than 1 month after you buy it. After that, it might not work.
Speeds depend on location and network load.
Your phone must support eSIM and be carrier-unlocked.

Install your eSIM at home on Wi-Fi, then switch on the MobiSIM line when you land in United States. Your plan's days only start on first connection.
Coverage is strongest in cities and along main transport routes. Download offline maps before heading into national parks or remote areas.
Your home SIM stays active for calls and SMS codes from your bank. WhatsApp and iMessage keep your usual number while MobiSIM handles data.
