Question 1

How do I activate my Funsim eSIM after purchase?

Accepted Answer

After payment, your eSIM appears under "My eSIM" in your account. Scan the QR code with another device's camera or use the "Quick install" button — activation takes 1–2 minutes. If the profile doesn't activate automatically, turn on mobile data for the new line in your phone settings.

Question 2

How do I install an eSIM manually?

Accepted Answer

If you can't scan the QR code, install it manually: Settings → Cellular → Add eSIM → Enter details manually, using the SM-DP+ address and activation code from your account. You may also need to set the APN for your plan — the correct APN is shown on your eSIM page in your account.

Question 3

The eSIM QR code won't scan or shows an error — what do I do?

Accepted Answer

Make sure the QR code is open on a different device (not the phone you're installing the eSIM on) and the screen isn't glaring. If the error repeats, try manual installation with the activation code, or manual APN entry. If nothing works, contact support and we'll reissue the eSIM.

Question 4

How do I remove an eSIM from my phone?

Accepted Answer

On iPhone: Settings → Cellular → select your Funsim plan → "Remove eSIM". On Android the path is usually Settings → Network & internet → SIM cards. A removed profile can't be restored on the same device — if your trip isn't over yet, disable the line instead of deleting it.

Question 5

Can I restore or re-download an eSIM I deleted?

Accepted Answer

A QR code can typically only be activated once, on one device, and a profile can't be reinstalled after deletion. If this happened by mistake, contact support with your order number and we'll check whether the eSIM can be reissued.

Question 6

How do I transfer an eSIM to a new phone?

Accepted Answer

An eSIM is tied to a specific device and doesn't transfer automatically when you switch phones. If you haven't activated it yet, just install it on the new phone. If it's already active, contact support to have it reissued for the new device.

Question 7

My eSIM is active but I have no internet — why?

Accepted Answer

This is usually because data roaming isn't enabled for the eSIM line. Check: Settings → Cellular → select the eSIM line → enable "Data Roaming". Also make sure the eSIM, not your physical SIM, is set as the data line.

Question 8

No internet right after landing — what should I check?

Accepted Answer

It can take 1–5 minutes after landing for your phone to register with the local network — try toggling Airplane Mode off and on. If it's still not working, check that date and time are set automatically and that data roaming is enabled for the eSIM.

Question 9

My eSIM was working, now it isn't — what happened?

Accepted Answer

Check your remaining data balance in your account — the connection stops once the plan's data or validity period runs out. If you still have data left, try manually selecting the network operator instead of automatic selection, then restart your phone.

Question 10

What does "no signal" or "not registered on network" mean?

Accepted Answer

This usually means the phone can't connect to any partner network in that country — for example, the device may be carrier-locked, or the eSIM isn't fully activated yet. Restart the phone and check the eSIM status in settings; contact support if it persists.

Question 11

Roaming charges won't turn off on my phone — how do I fix it?

Accepted Answer

This is usually about your home SIM's roaming, not the Funsim eSIM — turn off data roaming for your physical home SIM and leave only the eSIM line enabled, to avoid accidental roaming charges from your home carrier.

Question 12

How do I check if my phone supports eSIM?

Accepted Answer

On iPhone: Settings → General → About — if you see "Digital SIM information", eSIM is supported. On Android: Settings → About phone — look for an EID number. Funsim's website also has a dedicated eSIM compatibility checker by phone model.

Question 13

My phone doesn't detect the eSIM — what should I do?

Accepted Answer

Make sure the phone was purchased unlocked — carrier-locked devices often can't add a third-party eSIM. Check that you're on the latest OS version, and try manual code entry instead of scanning the QR code.

Question 14

iPhone doesn't detect the eSIM after scanning the QR code

Accepted Answer

eSIM is supported on iPhone XS, XR and newer (except certain dual-physical-SIM regional models). If the QR code won't scan, use manual setup: Settings → Cellular → Add eSIM Manually, and enter the activation code from your account.

Question 15

Android (Samsung, Xiaomi, Google Pixel) doesn't detect the eSIM

Accepted Answer

eSIM is supported on flagship Samsung Galaxy (S20 and newer), Google Pixel (3 and newer), and some international-version Xiaomi models — the phone must be the international variant, not a single-market regional build. Setup path: Settings → Connections / Network & internet → SIM manager → Add eSIM.

Question 16

Can I use two eSIMs at the same time?

Accepted Answer

Yes, modern smartphones store multiple eSIM profiles, though usually 1–2 lines are active simultaneously depending on the model. You can keep your home SIM and Funsim eSIM active together — calls stay on your home number while data runs through the eSIM.

Question 17

What is an eSIM and how is it different from a physical SIM?

Accepted Answer

An eSIM is a built-in digital SIM module: instead of a plastic card, you get a QR code and activate the carrier profile directly on your device. It's faster (no waiting for delivery or hunting for a SIM shop abroad) and more convenient for travel — you can keep several profiles and switch between them.

Question 18

How do I buy a Funsim eSIM online?

Accepted Answer

Pick your destination, choose a plan by data amount and validity, and pay by card — the eSIM QR code arrives in your account right after payment. You can activate it ahead of your flight, but only enable data roaming once you land, so you don't burn the plan's validity early.

Question 19

How much does a Funsim eSIM cost?

Accepted Answer

Price depends on the destination, data amount (GB) and validity period — current prices for each country are shown on that country's page. There are local plans (one country), regional plans (several neighboring countries) and global plans.

Question 20

Do I need a passport to buy an eSIM?

Accepted Answer

No, buying a Funsim tourist eSIM doesn't require a passport — unlike physical SIM cards in some countries, which require foreigner registration. A phone number for your account and a card payment are enough.

Question 21

Which eSIM plan should I choose for my trip?

Accepted Answer

For a single-country trip, a local plan is the better value. If your route covers several neighboring countries (a Europe tour, for example), a regional plan is usually cheaper than buying several local ones. Base your choice on trip length and expected data use: 1–3 GB for 7 days usually covers social media and maps, 5–10 GB or more suits work and streaming.

Question 22

Does Funsim offer unlimited data abroad?

Accepted Answer

Yes, unlimited plans are available for some destinations — marked separately on the country page. Unlimited plans typically have a fair-use speed cap after a certain amount of daily data; the exact terms are listed on that plan.

Question 23

How do I use an eSIM while traveling?

Accepted Answer

Once activated with data roaming turned on, your phone works as usual — use the internet, messaging apps and maps within your purchased data allowance. Most plans don't include voice calls or SMS — use WhatsApp, Telegram or FaceTime over the eSIM's data instead.

Question 24

How do I avoid roaming charges while traveling?

Accepted Answer

Turn off data roaming for your home SIM and keep only the Funsim eSIM enabled — that way your data runs through the plan you bought instead of your home carrier's expensive international roaming.

Question 25

Do WhatsApp and Telegram work over a Funsim eSIM abroad?

Accepted Answer

Yes — a Funsim eSIM is a mobile data plan, so every internet service works normally: WhatsApp, Telegram, voice and video calls through them, maps, social media. Plans don't include traditional carrier voice calls or SMS.

Question 26

Does the internet work on a plane?

Accepted Answer

An eSIM can't connect to ground networks in flight — in-air internet requires the airline's own Wi-Fi (where available), and the eSIM reconnects automatically once you land and register on the local network.

Question 27

How do I enable data roaming on my phone?

Accepted Answer

iPhone: Settings → Cellular → select the Funsim eSIM line → enable "Data Roaming". Android: Settings → Network & internet → SIM cards → select the Funsim eSIM → enable data roaming. Without this step, your data plan won't work abroad even after successful activation.

Question 28

How can I save data while traveling?

Accepted Answer

Turn off app auto-updates and cloud backups while roaming, limit video autoplay in social apps, and use hotel or café Wi-Fi for heavy downloads where possible, saving your eSIM data for navigation and messaging.

Question 29

Can I share my eSIM's internet as a hotspot?

Accepted Answer

Yes, most Funsim plans support hotspot/tethering — you can share your phone's connection with a laptop or another device within your purchased data allowance. Any plan-specific hotspot limits are noted on that plan's description.
