Frequently asked questions

Is this an eSIM or a physical SIM?

This product is a physical SIM card, not an eSIM. It is packed and shipped to your physical address. It cannot be delivered via QR code or email. Please ensure your delivery address, recipient name, and phone number are correct during checkout.

Can I renew and keep this physical SIM card for long-term use?

Yes, absolutely! All our physical SIM cards support continuous online renewal and long-term usage. You can top up balances and purchase data add-ons anytime directly on MollySIM (mollysim.com/top-up) or via the carrier's official mobile app / website. For popular cards like Giffgaff, CSL, Club SIM, T-Mobile, and Orange, you can keep your original phone number permanently by maintaining minimum periodic usage or top-ups.

When does the plan activate?

Where does this SIM work?

Does this physical SIM card support hotspot sharing (tethering)?

Yes, most of our physical SIM cards support mobile hotspot sharing by default, allowing you to share data with other phones, tablets, or laptops. Please make sure your device supports hotspot functionality and that network settings are configured correctly.

Does this card require Real-Name Registration?

Real-name registration requirements vary by country and carrier: some cards are ready to use plug-and-play without registration, while others require simple registration via the carrier's website or app before use. The exact registration steps, if any, are clearly printed on the outer packaging of the SIM card and sent via email.

How long does shipping take and how do I track my order?

After payment is confirmed, we will pack and ship your order within 24–48 hours. Standard shipping takes approximately 3–5 business days depending on your location. Once shipped, you will receive a tracking number via email, which you can also check in your MollySIM account under 'Orders'.

What is the return and refund policy?

We offer a flexible refund policy. If your plans change, unactivated and unused SIM cards in their original packaging can be fully refunded within 30 days of purchase. Once a card is activated or the packaging is opened, we cannot accept refunds unless there is a verifiable network or hardware defect.
