Question 1

What is an eSIM?

Accepted Answer

An eSIM (embedded SIM) is a digital SIM card built directly into your phone. Unlike traditional physical SIM cards, an eSIM allows you to activate a cellular plan without inserting a physical card. You simply scan a QR code or enter activation details, and your phone connects to the network. This makes it perfect for travelers who want instant connectivity without the hassle of buying and swapping physical SIM cards.

Question 2

How does an eSIM work?

Accepted Answer

An eSIM works by storing your carrier profile digitally on a chip embedded in your device. When you purchase an eSIM plan, you receive a QR code containing your profile information. Scanning this code downloads the carrier profile to your device, allowing it to connect to mobile networks. You can have multiple eSIM profiles stored on your device and switch between them as needed.

Question 3

What are the benefits of using an eSIM over a physical SIM?

Accepted Answer

eSIMs offer several advantages: 1) Instant activation - no waiting for delivery or finding a store, 2) No physical card to lose or damage, 3) Keep your primary number active while using data abroad, 4) Easy to switch between carriers and plans, 5) More environmentally friendly - no plastic waste, 6) Perfect for frequent travelers who visit multiple countries.

Question 4

Is eSIM better than buying a local SIM card?

Accepted Answer

For most travelers, yes. eSIMs offer instant activation before you even leave home, no need to find a store or deal with language barriers, and you keep your existing phone number for calls and messages. Local SIM cards can be cheaper for very long stays, but eSIMs win on convenience, speed, and the ability to be ready the moment you land.

Question 5

Can I use eSIM and physical SIM at the same time?

Accepted Answer

Yes! Most modern phones support Dual SIM functionality, allowing you to use both an eSIM and a physical SIM simultaneously. This is perfect for travelers - keep your home SIM for calls and texts, and use your eSIM for affordable data abroad. You can configure which SIM handles calls, texts, and data independently.

Question 6

Which phones support eSIM?

Accepted Answer

Most smartphones released since 2018 support eSIM. This includes: Apple iPhone XS and newer (including SE 2020+), Google Pixel 3 and newer, Samsung Galaxy S20 and newer, Galaxy Z Fold/Flip series, Motorola Razr, OnePlus, Xiaomi, Oppo, and many more. Use our Compatibility Checker to verify if your specific device supports eSIM.

Question 7

How do I check if my phone supports eSIM?

Accepted Answer

For iPhone: Go to Settings > General > About, and look for 'Available SIM' or 'Digital SIM'. For Android: Go to Settings > Network & Internet > SIM > Add SIM, and look for an eSIM option. Alternatively, dial *#06# to see if an EID (eSIM ID) is displayed. You can also use our Compatibility Checker page for a quick lookup.

Question 8

Does my phone need to be unlocked to use eSIM?

Accepted Answer

Yes, your phone must be carrier-unlocked to use an eSIM from a different provider. If you purchased your phone through a carrier with a contract, it may be locked. Contact your carrier to request an unlock, or check your phone's settings. Most phones purchased directly from manufacturers (Apple, Samsung, Google) are already unlocked.

Question 9

Can I use eSIM on my tablet or smartwatch?

Accepted Answer

Yes, many tablets and smartwatches support eSIM, including iPad Pro, iPad Air, iPad mini (cellular models), Apple Watch (GPS + Cellular), Samsung Galaxy Watch, and Google Pixel Watch. However, our travel eSIMs are primarily designed for smartphones. Check your device specifications for eSIM support.

Question 10

Why doesn't my phone show the eSIM option?

Accepted Answer

Several reasons could cause this: 1) Your phone model doesn't support eSIM, 2) Your phone is carrier-locked, 3) Your phone's software needs updating, 4) eSIM was disabled by your carrier. Try updating your phone's software first. If the issue persists, contact your carrier or check our Compatibility Checker.

Installation is easy! For iPhone: Go to Settings > Cellular > Add Cellular Plan, then scan the QR code we emailed you. For Android: Go to Settings > Network & Internet > SIM > Add SIM, then scan the QR code. The process takes about 1-2 minutes. Make sure you're connected to WiFi during installation.

Question 18

When should I install my eSIM?

Accepted Answer

We recommend installing your eSIM before you travel, while you still have WiFi access. You can install it days or even weeks before your trip - it won't activate until you turn it on or arrive at your destination (depending on the plan). This ensures you're connected the moment you land.

Question 19

Can I install the eSIM without WiFi?

Accepted Answer

You need an internet connection to install the eSIM (WiFi recommended). However, some phones allow manual installation using the activation code provided in your email, which can work with mobile data. We recommend installing via WiFi before your trip for the smoothest experience.

Question 20

What if I can't scan the QR code?

Accepted Answer

If you can't scan the QR code (e.g., viewing email on the same phone), you can manually enter the activation details. We provide an SM-DP+ address and activation code in your confirmation email. Go to your phone's eSIM settings, select 'Enter Details Manually', and input the provided information.

Question 21

How do I know if my eSIM is installed correctly?

Accepted Answer

After installation, you should see a new cellular plan in your phone's settings (it may appear as the carrier name or a generic label). On iPhone, go to Settings > Cellular to see your plans. On Android, go to Settings > Network & Internet > SIM. The eSIM should show as 'Active' or 'Ready to use'.

Question 22

Can I reinstall my eSIM if I delete it?

Accepted Answer

Most eSIMs can only be installed once for security reasons. If you accidentally delete your eSIM before using it, contact our support team immediately with your order details. We'll verify your purchase and help you with a replacement if the eSIM hasn't been activated.

Question 23

How do I turn on my eSIM when I arrive?

Accepted Answer

Once installed, go to your phone's cellular settings and enable the eSIM. On iPhone: Settings > Cellular > [eSIM Plan] > Turn On This Line, and enable Data Roaming. On Android: Settings > Network & Internet > SIM > [eSIM] > Enable. Your phone should connect to a local network within seconds.

Question 24

Do I need to enable data roaming?

Accepted Answer

Yes, you typically need to enable data roaming for your eSIM to work abroad. Don't worry - our eSIM plans include international data at no extra charge, so enabling roaming won't result in surprise bills. Go to Settings > Cellular > [eSIM Plan] > Data Roaming and turn it on.

Question 25

Can I make phone calls with my eSIM?

Accepted Answer

It depends on your plan type. Data-only plans provide internet access only - you can make calls using apps like WhatsApp, FaceTime, Zoom, or Skype. Voice + Data plans include traditional calling minutes and SMS. Check your plan details before purchasing if calling is important to you.

Question 26

How do I check my remaining data?

Accepted Answer

You can check your data usage in your phone's settings: iPhone: Settings > Cellular > [eSIM Plan] shows usage for the current period. Android: Settings > Network & Internet > SIM > [eSIM] > Data usage. Note that these are estimates - for exact remaining data, log into your OctoSim.io account.

Question 27

What happens when I run out of data?

Accepted Answer

When your data allowance is depleted, your internet connection will stop working. You won't be charged extra - there are no overage fees. To continue using data, you can purchase a new eSIM plan or top-up package (where available). Your calls and texts on your primary SIM will continue working normally.

Question 28

Can I use my eSIM in multiple countries?

Accepted Answer

Single-country eSIMs work only in the specified country. However, we offer Regional eSIMs that cover multiple countries (e.g., Europe, Asia, Americas). These are perfect for multi-country trips - one plan works across all covered destinations with no need to switch eSIMs at each border.

Question 29

What speeds can I expect?

Accepted Answer

Our eSIMs provide 4G LTE and 5G speeds where available, typically offering download speeds of 10-100+ Mbps. Actual speeds depend on local network conditions, coverage, and congestion. In most urban areas, you'll enjoy fast, reliable connectivity for streaming, video calls, and browsing.

Question 30

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

Accepted Answer

Try these steps: 1) Ensure the eSIM is enabled in Settings, 2) Turn on Data Roaming, 3) Restart your phone, 4) Manually select a network (Settings > Cellular > Network Selection > Manual), 5) Reset network settings as a last resort. If issues persist, contact our 24/7 support team with your order details.

Question 31

Why is my connection slow?

Accepted Answer

Slow speeds can be caused by: network congestion (busy areas/times), weak signal (try moving to a different location), background apps using data, or local network conditions. Try toggling airplane mode on/off, or manually selecting a different network carrier in your settings.

Question 32

My eSIM disappeared from my phone. What happened?

Accepted Answer

eSIMs can be removed if you reset your phone, update iOS/Android, or accidentally delete the profile. If the eSIM was never activated, contact support for a replacement. If it was already in use, you'll need to purchase a new plan. We recommend taking a screenshot of your QR code as a backup.

Question 33

The QR code isn't scanning. What should I do?

Accepted Answer

Ensure your screen brightness is high and the QR code is fully visible. Try cleaning your camera lens. If viewing on the same device, use the manual activation code instead (found in your email). You can also try opening the QR code on another device's screen to scan it.

Question 34

I received an error during installation. What does it mean?

Accepted Answer

Common errors include: 'eSIM cannot be added' (device/carrier lock issue), 'Invalid QR code' (try manual entry), 'eSIM already installed' (check existing profiles), 'Network error' (check WiFi connection). Note the exact error message and contact support if you can't resolve it.

Question 35

Can I get a refund if my eSIM doesn't work?

Accepted Answer

Yes, we offer refunds for eSIMs that fail to work due to technical issues on our end. Refunds are typically not available for user error (wrong destination purchase), device incompatibility that wasn't checked, or used/activated eSIMs. Contact support within 30 days of purchase for assistance.

Question 36

Do I need an account to purchase an eSIM?

Accepted Answer

No, you can purchase as a guest using just your email address. However, creating a free account lets you: view order history, re-download QR codes, manage multiple eSIMs, and get faster checkout on future purchases. We recommend creating an account for the best experience.

Question 37

How do I view my order history?

Accepted Answer

If you have an account, log in and go to 'My Orders' to see all your purchases, download QR codes, and view plan details. If you purchased as a guest, use the order lookup feature with your email address and order ID (found in your confirmation email).

Question 38

I didn't receive my confirmation email. What should I do?

Accepted Answer

Check your spam/junk folder first - emails sometimes get filtered. Make sure you entered the correct email address during purchase. If you still can't find it, log into your account to access your order, or contact support with your payment confirmation for assistance.

Question 39

Can I transfer my eSIM to another device?

Accepted Answer

eSIMs are generally tied to the device they're first installed on and cannot be transferred. If you get a new phone, you'll need to purchase a new eSIM. Some carriers allow eSIM transfer, but for travel eSIMs, this is typically not supported due to security protocols.

Question 40

How long is my eSIM valid?

Accepted Answer

eSIM validity varies by plan - most plans are valid for 7-30 days from activation. Some plans start on first data use, others on installation. Check your specific plan details for validity period. Unused eSIMs typically remain available for installation for 6-12 months from purchase.
