The USA is a huge country, and network quality varies a lot by state: fast 5G in cities like New York and Los Angeles, more modest coverage in remote areas. Here's which eSIM plan to pick for a city trip, a road trip, or a business visit.
For a single-city trip — New York, Los Angeles, Miami or Las Vegas — with navigation, ride-hailing apps and social media, 5–8 GB per week is usually enough. For a multi-state road trip with constant turn-by-turn navigation, go for 15–20 GB or more.
Keep in mind that many US apps and services rely heavily on location tracking and background data, so data tends to run out faster than in more compact countries.
Coverage is fast and reliable almost everywhere in New York, Los Angeles, San Francisco, Miami and Orlando, including subways in major cities. In national parks (Grand Canyon, Yellowstone) and on long interstate drives, signal can drop out — that's down to terrain, not the carrier, so it's worth downloading offline maps for those routes.
You can install the eSIM profile ahead of time, while still in Kazakhstan — handy if your flight has layovers and you want connectivity at the transit airport too. Only turn on data roaming after you land in the US, so you don't waste days of validity early.
