Frequently asked questions
An eSIM is a digital SIM built into your phone. Instead of inserting a plastic card, you scan a QR code and a travel data plan installs in seconds — nothing to ship, swap, or lose.
No. You can buy as a guest and check out in seconds — no account, registration, or password required. We only need an email address to deliver your QR code.
About 30 seconds. After purchase you receive a QR code by email, scan it to install the eSIM, then turn on data roaming for the Lumo line to get online.
Lumo works across 160+ countries and regions through 70+ tier-one carrier partners, automatically connecting you to the strongest local network with 5G/4G where available.
Most eSIM-capable iPhones, Android phones, tablets, and laptops are supported. Check the Compatible Devices page before you buy — on dual-SIM phones you can keep your regular SIM active for calls and texts.
Lumo eSIMs are data-only: they provide mobile internet with no calls, SMS, or phone number. Keep your primary SIM active for voice and text, and use Lumo for data. Apps like WhatsApp and iMessage work over data.
None. Plans are prepaid with no contracts and no surprise roaming charges — you only pay for the data you buy up front.
Yes. If your eSIM has not been installed or used yet, you can cancel it from your account for a refund — so there is no risk in trying it. Refunds are only available for unused, uninstalled eSIMs and take 3-5 business days to process.
Each eSIM profile installs on one device only and cannot be moved or shared between devices. Buy a separate plan for each device you want to connect.
