USA & Canada eSIM data plans
The United States and Canada are covered by the same handful of big networks, and a travel eSIM is the cheapest way to stay online without an expensive roaming add-on from a Mongolian operator. Install the eSIM before you fly and the line is usually up before the plane reaches the gate.
A single-country plan for the USA or for Canada gives the best price when the trip stays inside one country. Anyone crossing the border — Toronto to New York, Vancouver to Seattle, or a long drive through both — should take the North America bundle instead: one balance that does not reset at the border.
Plans are prepaid, data-only and priced in MNT: no credit check, no monthly contract, no activation fee. Data counts from the first connection to a US or Canadian network, so a plan bought a week early does not burn its validity while it sits installed. My GlobalSIM handles top-ups, and hotspot sharing with a laptop or a second phone works on every plan on this page.
