eSIMstep is operated from New Westminster, BC, Canada. Customers can contact support for installation help, refund questions, and account issues before deleting an eSIM from their device.
Your high-speed data allowance is used first. Once it runs out, your connection is NOT cut off. Instead, your speed is reduced to 1 Mbps, which is sufficient for basic tasks like messaging and light browsing.
Daily unlimited plans can be extended before the eSIM expires. After the validity ends, the eSIM cannot be topped up and a new eSIM is required.
Your internet traffic is NOT routed through Hong Kong servers, which would otherwise cause higher latency and slower speeds.
This means lower ping and a faster, more stable connection for video calls, streaming, and real-time apps.
You are assigned a US IP address regardless of your physical location.
This allows you to bypass geographic restrictions and access US-only services such as banking apps, streaming platforms, and region-locked websites from anywhere in the world.
Eligible plans receive free calling minutes based on the plan price.
Unused eSIMs may be refunded free of charge within 30 days. Installed, activated, downloaded, accessed, consumed, or used eSIMs are non-refundable except for qualifying technical or service issues.
Eligible for Refund (within 30 days):
