Question 1

What is an eSIM and how does it work?

Accepted Answer

An eSIM (embedded SIM) is a digital SIM that allows you to activate a cellular plan without using a physical SIM card. It's built into your phone and can be activated by tapping an installation link. You can use it alongside your regular SIM for dual connectivity.

Question 2

Is my phone compatible with eSIM?

Accepted Answer

Most modern smartphones support eSIM, including iPhone XS and newer, Google Pixel 3 and newer, Samsung Galaxy S20 and newer, and many other Android devices. Your phone must also be carrier-unlocked. Check our device compatibility page to verify your specific model.

Question 3

How do I install an eSIM?

Accepted Answer

After purchasing, you'll receive your eSIM via email instantly. On compatible devices (iOS 17.4+ and Android 10+), simply tap the installation link to add it automatically. For older devices, copy the activation code and paste it in Settings > Cellular > Add eSIM (iPhone) or Settings > Network & Internet > SIMs (Android). The process takes under 2 minutes!

Question 4

When does my eSIM data plan start?

Accepted Answer

Your data plan validity period begins when you first connect to a network at your destination, not when you purchase or install the eSIM. This means you can buy and set up your eSIM before traveling, and it will only activate upon arrival.

Question 5

Can I use my eSIM for hotspot/tethering?

Accepted Answer

Yes! All Lumbus eSIM plans include hotspot and tethering capability. You can share your data connection with laptops, tablets, or other devices. Just enable the hotspot feature in your phone settings.

Question 6

What happens to my regular phone number?

Accepted Answer

Your regular SIM card and phone number continue to work normally. The eSIM provides data only, so you'll use it for internet while your regular SIM handles calls and texts. You can also use WiFi calling apps like WhatsApp for free calls over your eSIM data.

Question 7

Can I top up or extend my eSIM plan?

Accepted Answer

Yes! If you run out of data before your validity period ends, you can easily purchase a top-up through our website or app. Top-ups are instant and extend your connectivity without needing to install a new eSIM.

Question 8

Is eSIM better than buying a local SIM card?

Accepted Answer

eSIM offers several advantages: set up in seconds with no airport queues, ready before you travel, no language barriers, competitive prices, keep your regular number active, and easy top-ups. It's the most convenient way to stay connected abroad.

Question 9

How should I manage multiple eSIMs?

Accepted Answer

Two simple habits help. First, give each eSIM a name you'll recognize when you install it — your phone lets you label it (like "Japan trip") so you can always tell your eSIMs apart. Second, before adding a new eSIM, clear out any that have expired or that you've finished with — just double-check it's an old one. If you delete one by mistake, you can usually reinstall it on the same phone by tapping its original install link or re-scanning its QR code, as long as the plan is still valid, active and has data left — but an eSIM can't be moved to a different phone.

Question 10

How do unlimited plans work?

Accepted Answer

Unlimited plans give you 3GB a day at full speed. Once you've used the day's 3GB, you stay online without any volume limit but at a reduced speed of 1Mbps — enough for maps, messages, email and music, too slow for HD video. Your full-speed allowance comes back every 24 hours. Plans run 3, 7, 14 or 30 days, and you can add more days anytime while the eSIM is active.
