An eSIM for USA from UK is a digital SIM you install before flying, so you land online. Slashtel offers 16 plans, 1GB to 50GB, 7 to 90 days, on Verizon, AT&T or T-Mobile with 5G. Data only, hotspot allowed, no account needed.
What you get with a USA eSIM from the UK
A USA eSIM from Slashtel is a data only plan. There is no local phone number. Calls and messages work over data apps such as WhatsApp. The QR code arrives by email within minutes of payment and no account is needed.
Validity starts when the eSIM first connects at the destination, so you can buy and install it before flying. Keep your home SIM in the phone for calls and bank OTP texts. Turn off data roaming on the home SIM to avoid charges. Hotspot and tethering are allowed.
More data can be added to the same eSIM later, with no new QR code. The phone must be unlocked and eSIM compatible. The network is chosen automatically for the best signal and cannot be picked by hand. Some USA plans use a US IP address (breakout), so US banking and streaming apps behave as expected.
Best eSIM for USA from UK: how to choose
The best eSIM for USA from UK depends on trip length and data use. For a short city break, 1GB to 3GB over 7 days is often enough for maps, messages and light browsing. For a two week holiday, 5GB to 10GB over 15 days gives more room for photos, video and hotspot.
For longer stays or heavy use, 15GB to 50GB over 30 or 90 days is the practical choice. If you stream a lot or work remotely, the 50GB plan is the largest fixed option. Unlimited daily plans are also available on a separate page.
All plans run on Verizon, AT&T or T-Mobile with 5G where available. The network is picked automatically for the best signal.
