Customers are saying

Customers highly value the affordability, ease of use, and reliable coverage of the 1-Month 4GB Prepaid SIM Card. Many appreciate the included international calling features and the straightforward setup process. While some users experienced compatibility issues with certain phones, the positive feedback on price, data allowance, and network performance outweighs these concerns. The SIM card is frequently praised as a convenient option for temporary use or travel.

    I bought this card to setup for a hotspot. The first GB of data was real good speeds. Then as soon as I hit the 1GB mark it was throttled to 0.08-0.12MB down and 0.2 up. I checked these speeds numerous times and they did not go past these numbers. Next time I will try a different prepaid card. These speeds are ok for checking email and that is pushing it. No videos and probably no Amazon music.

    The SIM card had expired in August 2022 (didn’t know this was a thing). You don’t really know this when purchasing because it’s on the back of the SIM card and not indicated anywhere on the packaging. When I called to activate, the agent basically said the sim card had expired and it can’t be activated.
