Question 1

What is an eSIM?

Accepted Answer

An eSIM (embedded SIM) is a digital SIM card built into your device. Instead of inserting a physical SIM card, you can activate a cellular plan digitally. It works just like a traditional SIM but is more flexible and convenient.

Question 2

Is my device compatible with eSIM?

Accepted Answer

Most modern smartphones support eSIM, including iPhone XS and newer, Google Pixel 3 and newer, and Samsung Galaxy S20 and newer. Check our Device Compatibility page for a full list.

Question 3

How do I know if my phone is unlocked?

Accepted Answer

Contact your carrier to confirm your device is unlocked. Most phones purchased directly from manufacturers or at full price are unlocked. Carrier-locked devices won't work with eSIMs from other providers.

Question 4

How long does delivery take?

Accepted Answer

Your eSIM is delivered instantly after purchase! You'll receive an email with your QR code and activation instructions within seconds. No waiting for physical delivery.

Question 5

How do I install my eSIM?

Accepted Answer

For iPhone: Go to Settings > Cellular > Add eSIM, then scan the QR code or use the one-tap installation link. For Android: Go to Settings > Network & Internet > SIMs > Download a SIM, then scan the QR code.

Question 6

When should I install my eSIM?

Accepted Answer

You can install your eSIM anytime after purchase, but only turn on data when you arrive at your destination. This ensures your validity period starts when you actually need it.

Question 7

Can I install the eSIM before my trip?

Accepted Answer

Yes! You can install the eSIM before you travel. Just don't activate it (turn on cellular data) until you reach your destination. Your validity period starts when you first connect to a network.

Question 8

What if I can't scan the QR code?

Accepted Answer

You can enter the activation details manually. Go to your device's eSIM settings and select "Enter Details Manually", then input the SM-DP+ address and activation code provided in your email.

Question 9

Do I need to remove my primary SIM card?

Accepted Answer

No! Your eSIM works alongside your existing SIM. You can use both simultaneously - for example, keep your primary SIM for calls and SMS, while using the eSIM for data.

Question 10

Can I use hotspot/tethering?

Accepted Answer

Yes! All Lumbus eSIM plans support mobile hotspot and tethering. You can share your data connection with other devices like laptops or tablets.

Question 11

What speeds can I expect?

Accepted Answer

You'll get 4G/LTE or 5G speeds depending on your plan and local network availability. Our eSIMs automatically connect to the best available network in your destination.

Question 12

What happens when I run out of data?

Accepted Answer

When you run out of data, your connection will stop. You can purchase a top-up plan from your dashboard to add more data. Your validity period remains the same when you top up.

Question 13

What payment methods do you accept?

Accepted Answer

We accept Apple Pay, Google Pay, and all major credit cards (Visa, Mastercard, Amex, Discover). All payments are securely processed through Stripe.

Question 14

When does my plan start?

Accepted Answer

Your plan validity starts when you first connect to a mobile network with data enabled. Installing the eSIM doesn't start the countdown - only using it does.

Question 15

Can I get a refund?

Accepted Answer

Yes, you can request a refund before activating your eSIM (before first data connection). Once activated, eSIMs cannot be refunded as the service has been consumed.

Question 16

Do you offer unlimited data plans?

Accepted Answer

We offer high-capacity data plans up to 20GB. For most travelers, 5-10GB is sufficient for navigation, messaging, and moderate browsing. Check our plans page for specific options.

Question 17

My eSIM isn't connecting. What should I do?

Accepted Answer

First, ensure data roaming is enabled and your eSIM is set as the primary data line. Try toggling airplane mode on/off, or restart your device. If issues persist, contact our support team.

Question 18

I see "No Service" on my device.

Accepted Answer

Make sure you're in an area with coverage and that your device isn't in airplane mode. Check that the eSIM is installed correctly and cellular data is enabled for it.

Question 19

How do I check my data usage?

Accepted Answer

You can check your data usage in two ways: 1) Through your device's settings (Cellular/Mobile Data), or 2) In your Lumbus dashboard where you can see real-time usage statistics.

Question 20

Can I use my eSIM in multiple devices?

Accepted Answer

No, each eSIM can only be installed on one device. If you need connectivity for multiple devices, you can either use hotspot/tethering or purchase separate eSIMs.
