SmartSIM eSIM US, Europe & 51 Countries
A data-only prepaid eSIM with five plans from a 7-day 1GB trial to 180 days and 30GB, covering the US, Europe and more.
Is the SmartSIM 51-country eSIM worth buying?
For a short trip or a spare data line, it is a tidy, cheap option, and you can start with the $5.99 one-week plan to test coverage. It is data only, so no phone number, calls or texts. The page is a bit messy: the header says AT&T and Verizon, the description adds T-Mobile, and a stray reference to a different brand name appears in the text. Treat it as a product that needs a test run before you rely on it.
A flexible eSIM with five plans
The listing offers 7 days with 1GB ($5.99), 30 days with 5GB ($12.99), 30 days with 12GB plus an unlimited 256kbps tier ($29), 90 days with 6GB ($15.99) and 180 days with 30GB ($55). SmartSIM says it covers 51 countries and connects to top carriers including AT&T and Verizon in the US and Orange, Vodafone and Telefónica in Europe.
What makes it stand out
From 7 days to 180 days
Five plans range from $5.99 up to $55. The long 180-day, 30GB option works out to about $1.83 per GB, and the 7-day plan is a cheap way to try the service.
Scan, roam, set APN
SmartSIM says to scan the QR code in your phone's cellular settings, enable roaming, and set the APN to "plus". The plan is described as valid from first use, and it must be activated before use.
51 countries
Coverage is marketed across 51 countries with automatic carrier selection. The listing names AT&T and Verizon in the US and Orange, Vodafone and Telefónica in Europe.
Phones, tablets and IoT
It is described as compatible with Android and iOS phones, tablets and unlocked 4G IoT devices such as Wi-Fi routers. A device with eSIM support is needed.
