Mobile networks in the USA: operators and coverage
The US market is dominated by AT&T, T-Mobile and Verizon. Travel eSIMs use one or more of these networks. Coverage is good in cities, but national parks and long stretches between towns have dead spots – whichever eSIM you use. For road trips it is worth saving maps offline in advance. Many US packages only cover the USA; Canada and Mexico are then not included.
How much data do I need?
- Messaging, maps and e-mail only: around 0.5–1 GB per week.
- Plus social media and photo uploads: more like 1–2 GB per week.
- Video streaming or a hotspot for your laptop: easily 1–3 GB per day – a larger or unlimited package pays off here.
These are rough guide values; your actual usage depends on apps and video quality. You can see your own usage in your phone settings under “Mobile data”. Many providers let you top up an eSIM if the data runs out.
Unlimited or a data package?
9 of the 9 providers offer unlimited data packages in the USA. The cheapest per day is Simbye: 7 days for €19.95, i.e. €2.85 per day. Provider note: 2 GB per day at full speed, then throttled. “Unlimited” often means the speed is throttled after a certain amount per day, and hotspot use may be restricted. If you stream little, a fixed package is usually cheaper.
How to set up the eSIM
- Check your phone: it must support eSIM and be unlocked (iPhone XS/XR or later, many current Android devices). Under “Settings → Mobile data” or “Connections → SIM manager” you can see whether “Add eSIM” is offered.
- Buy and install the package: ideally at home on Wi-Fi, via QR code or directly in the provider's app.
- Activate on arrival: switch mobile data to the travel eSIM and enable data roaming for that eSIM. Your home SIM can stay active for calls and texts – turn off data roaming on it to avoid extra charges.
When the validity starts is up to each provider: often only with the first connection in the destination country, sometimes at installation. The package details say which applies.
