Best eSIMs for
United States 🇺🇸

An eSIM (embedded SIM) is a digital SIM that allows you to activate a cellular plan without a physical SIM card. In the United States, eSIMs connect to local networks like T-Mobile, giving you fast mobile data access without buying a physical SIM at the airport or a local shop. Most modern smartphones (iPhone XS and later, Samsung Galaxy S20 and later) support eSIM.

Based on our price comparison, Roambit offers the cheapest 20GB plan for the United States at just $19.99 for 30 days. That's about $5 cheaper than the next competitor (Strong eSIM at $24.00) and more than $10 cheaper than providers like Saily or Airalo for the same data amount.

Not all eSIM providers allow hotspot usage. Roambit explicitly supports hotspot/tethering with their United States plans, while some competitors do not clearly state hotspot flexibility. Always check the provider's terms before purchasing if hotspot usage is important for your trip.

Most United States eSIMs are delivered instantly after purchase and can be activated within minutes by scanning a QR code. Roambit offers up to 180 days to activate after purchase, and the validity period only starts when you first use mobile data – not at the moment of purchase.

Most travel eSIMs for the United States, including Roambit, are data-only plans. This means they provide mobile internet access but do not include voice calls or SMS. You can use apps like WhatsApp, Telegram, or Skype for calls and messaging over your data connection.
