Quick answers about your travel eSIM.
Will it work on my phone?
Your phone must support eSIM and be unlocked from its carrier. Check your phone's settings or ask your carrier.
When does my plan start?
Validity starts the first time you connect at your destination, not when you buy or install the eSIM. Some plans start at installation instead; they are clearly labeled, so install those after you arrive.
How do I install my eSIM?
Open your order page or email on your phone and tap Install eSIM (iPhone), or scan the QR code. Step-by-step instructions for iPhone and Android are in the install guide.
My phone says my eSIM couldn't be activated. What now?
If you installed it before your trip, this is normal: the eSIM connects when you arrive. The message may name another mobile network. You don't need to contact them, and don't delete the eSIM. When you land, turn on the eSIM line and data roaming for it. Still no signal? Contact us.
Does it connect to more than one network?
In most countries, yes. Your phone picks the network with the best signal and switches to another if the signal drops. You can see which networks are used on each country's page.
When should I install my eSIM?
Before you travel, while you still have Wi-Fi. Then switch it on when you land.
Can I buy a data add-on later?
Yes. On plans that support data add-ons, you can add data to the same eSIM.
Can I get a refund?
Yes. If you haven't installed the eSIM, you get a full refund until its install deadline. Installed eSIMs can't be refunded; if one doesn't work on the network, contact support and we'll look into it.
Can I share my connection (hotspot)?
Works on most plans. To be sure, contact us before you buy.
Do I get a phone number?
No. lumsim plans are data only, with no phone number, calls or SMS. You can still use messaging and calling apps over data.
Can I have more than one eSIM?
Yes. Most phones can store several eSIMs, but only a limited number can be on at the same time. The limit depends on your phone.
Do I get an invoice?
Yes. We email you an invoice after payment. For a company invoice, enter your company details at checkout.
Why can't I buy yet?
lumsim is not available yet in some regions. Where purchases are not open, you'll see "Coming soon".
