Find answers to common questions about eSIMs, installation, and your account.

Getting started

What is an eSIM?
An eSIM (embedded SIM) is a digital SIM card built into your device. It allows you to activate a mobile data plan remotely without needing a physical SIM card.
Is my device compatible?
Most modern smartphones support eSIM: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later, and many other Android flagship phones. Go to Settings โ†’ Cellular โ†’ Add eSIM on iOS, or Settings โ†’ Network โ†’ SIM on Android to check.
Do I need to remove my current SIM?
No. You can use your regular SIM and eSIM simultaneously (dual SIM). Keep your existing number for calls while the eSIM handles data.

Installation

How do I install my eSIM?
You have three options: (1) Tap the "Install eSIM Now" button on mobile browsers โ€” it opens your device's eSIM wizard directly. (2) Scan the QR code with your phone's camera app. (3) Enter the SM-DP+ address and activation code manually in Settings โ†’ Cellular โ†’ Add eSIM.
The QR code is not working โ€” what do I do?
Make sure you are connected to Wi-Fi or your regular mobile data when installing. Try the manual entry method as a fallback. If it still fails, contact support.
Can I install the eSIM on multiple devices?
No. Each eSIM profile is tied to one device. Once installed, it cannot be transferred.

Data & plans

When does my data plan start?
Your plan duration begins when you first use mobile data with the eSIM active โ€” not at the time of purchase.
What happens when I run out of data?
Your eSIM will continue to work for calls and SMS if your device supports it, but mobile data will stop. Purchase a new plan to continue.
Do plans auto-renew?
No. All plans are one-time purchases. You are never charged automatically.

Payments & refunds

What payment methods do you accept?
We accept all major credit and debit cards (Visa, Mastercard, Amex) and Apple Pay via Stripe.
Can I get a refund?
If you have not installed the eSIM yet, you can request a refund within 24 hours of purchase from your Order History page. Once an eSIM is installed and data is used, we cannot issue refunds.
