Customer feedback
Amazing service, trusted by travelers
Real usage stories from short city breaks, remote-work travel, and long multi-country itineraries.
Fast and reliable setup with clear instructions. I activated before landing, scanned the QR in minutes, and had stable data as soon as the plane touched down.
Traveler ReviewCheckout was smooth with PayPal, and the order timeline updated quickly in the dashboard so I always knew whether my eSIM was processing or ready.
Frequent FlyerThe mixed plan options were exactly what I needed for a multi-country trip. I could compare validity and data clearly instead of guessing at checkout.

Frequently Asked Questions
Core answers before checkout: compatibility, activation, validity, payments, and refunds.
What is an eSIM and how is it different from a physical SIM?
An eSIM (embedded SIM) is a digital profile installed directly on your phone — no physical card required. You download and activate it over the internet, allowing instant connectivity without visiting a store. Your home SIM remains active at the same time, so you can use the eSIM for travel data while keeping your usual number for calls and texts.
How do I know if my phone supports eSIM?
Most flagship smartphones released after 2018 support eSIM, including iPhone XS/XR and later, Samsung Galaxy S20 and later, and Google Pixel 3 and later. Go to Settings > About Phone (Android) or Settings > General > About (iPhone) to verify eSIM support. Your device must also be carrier-unlocked to activate a third-party eSIM plan.
What is a QR code and how do I use it to install an eSIM?
After your order is fulfilled, a QR code is sent to your email and saved in your MollySIM account. To install: open Settings > Cellular (or Mobile Data) > Add eSIM, then select Scan QR Code and point your camera at the code. The profile installs automatically. Complete this step while connected to stable Wi-Fi.
When should I install my eSIM for travel?
Install while you have stable Wi-Fi, ideally before departure. Activate the line when you arrive, based on your travel timing and plan validity.
What happens if I run out of data?
Once your data allowance is fully used, the connection will either stop or be reduced to a lower speed depending on the plan type. You can purchase a new plan for the same destination immediately from your account. Your order history allows quick repeat purchases without re-entering your details.
Which payment methods are supported?
We accept credit and debit cards via Stripe and PayPal. Depending on your browser and device, Apple Pay or Google Pay may also appear at checkout. All payments are processed securely by our payment partners — MollySIM does not store card details on our servers.
Can I get a refund if my plan is unused?
Refund eligibility is assessed case by case under our Refund Policy. Unused plans that have not been activated may qualify if requested promptly. Once a plan is activated or its validity period has started, refunds are generally not available. Submit your request via the Refund Policy page with your order ID and the reason for your request.
