SmartSIM International Data SIM Card
A physical prepaid data SIM for the US and 51 countries, with plans from 5GB for 30 days at $18 to 20GB for 90 days at $49.
Is the SmartSIM International Data SIM worth buying?
If your device has no eSIM or you want to swap a SIM into a hotspot or tablet, this is the physical version of the same service. Prices are fair at $18 for 5GB, $26 for 12GB and $49 for 20GB over 90 days. It is data only, and the listing clearly says so. Like the eSIM, the page shows different brand names in places, and there are no customer reviews.
A data-only SIM for travel
The listing says 5G/4G LTE coverage in the USA and 51 countries across the UK, Europe, Asia and Oceania, compatible with unlocked 4G devices such as smartphones, security cameras, routers, mobile hotspots, GPS trackers and tablets. It supports AT&T and Verizon.
What makes it stand out
5GB, 12GB or 20GB
Choose 5GB for 30 days ($18), 12GB for 30 days ($26) or 20GB for 90 days ($49). The 90-day plan is the best fit for a longer trip.
APN configuration
The page gives APN steps for iPhone, Android and Samsung, plus a router procedure. The APN is "plus" and no username or password is needed. Data roaming must be enabled.
Anything unlocked and 4G
It works in unlocked 4G phones, tablets, mobile hotspots, cameras and GPS trackers. The device must be unlocked.
No contract or activation fee
The description lists no contract, no credit check, no activation fee and no personal ID. The SIM is a new card with a plan rather than a refill, valid from first use.
