Airalo eSIM Not Working? Fixes That Actually Help (2026)

Most Airalo "not working" cases come down to one of three things: data roaming is switched off for the eSIM, the Airalo eSIM is not set as your data line, or the APN was never entered - and all three are fixable in about two minutes. Before you assume the eSIM is faulty or start a support ticket, walk through the checks below in order. They mirror Airalo's own troubleshooting guide, and they clear the large majority of cases. If none of them help, the last two sections cover when it really is Airalo's problem and what to do next.

Is data roaming turned on for the Airalo line?

This is the single most common cause. A travel eSIM connects to a local partner network, which your phone treats as roaming - so if data roaming is off, you get no internet even though everything else looks fine.

On iPhone: Settings > Cellular (or Mobile Data) > tap the Airalo line > turn on Data Roaming. Airalo flags one detail directly: on iPhone you toggle roaming per line, so turn it on for the Airalo eSIM and off for your home SIM to avoid home-network charges.

On Android (Samsung and most others): Settings > Connections > Mobile networks (or SIM manager) > select the Airalo eSIM > enable Data Roaming. On many Android phones roaming applies to all SIMs at once, so temporarily turn your home SIM off while you use the eSIM.

Toggle it on, wait a few seconds, and check for bars and a data icon.

Is the Airalo eSIM set as your data line?

Your phone can hold several SIMs, but only one carries mobile data at a time. If your home SIM is still the data line, the Airalo eSIM sits idle no matter how healthy it is.

On iPhone: Settings > Cellular > Cellular Data, and select the Airalo plan. While you are there, leave "Allow Cellular Data Switching" off so your phone does not quietly fall back to your expensive home line.

On Android: Settings > Connections > SIM manager > Mobile data, and choose the Airalo eSIM as the preferred data SIM.

Airalo's guide makes the same point: the eSIM has to be both installed and specifically "selected for data" before it will carry traffic. This one catches a lot of people who installed the eSIM correctly but never flipped the data line over.

Do you need to set the APN?

The APN (Access Point Name) is the address your phone uses to reach the carrier's data network. For most Airalo eSIMs it is applied automatically, so you should not need to touch it. But some plans require a specific APN, and if it is missing or wrong you will connect to the network yet get no working internet. Airalo sends the correct APN in your in-app installation instructions, so check there first before typing anything.

On iPhone: Settings > Cellular > tap the Airalo line > Cellular Data Network (or APN Settings) and enter the APN exactly as Airalo shows it. Leave username and password blank unless the instructions say otherwise.

On Android: Settings > Connections > Mobile networks > Access Point Names > add a new APN, enter the value from the Airalo app exactly, save it, and select it as the active APN.

Type the APN character for character - a stray space or capital letter is enough to break it. If the field was already filled and still not working, resetting it to Airalo's stated value is the fix.

Did the eSIM actually activate, or are you outside the coverage area?

Two separate things get confused here.

Activation timing. An Airalo eSIM usually activates when it first connects to a supported network in your destination, not the moment you install it. So "no service" while you are still at home or in the air is often normal - it should come alive once you land and are in range. Airalo covers this in its note on why an eSIM can take a while to activate. Give it a few minutes after arrival and a restart.

Coverage. Even activated, the eSIM only works where its host network has signal. If you are deep rural, indoors behind thick walls, or somewhere the partner carrier is weak, you will struggle. Step outside, or force a fix by turning off automatic network selection and picking an available network manually - it sometimes lands you on a stronger one.

A quick reset that resolves a surprising number of cases: turn on Airplane mode, wait about ten seconds, turn it off, then restart the phone.

Still no internet after all that?

If roaming is on, the data line is correct, the APN matches, and you are activated and in coverage, run this short checklist before contacting support:

• Disable other SIMs temporarily. Another active SIM can interfere; switch it off and test the eSIM alone.
• Change the network mode. Try forcing 4G/LTE instead of 5G (or the reverse) - some partner networks behave better on one.
• Confirm you have data left. Check remaining balance in the Airalo app; an empty plan looks exactly like a broken one.
• Reinstall as a last resort. Only if Airalo support tells you to, since an eSIM profile can usually be installed a limited number of times.

Work through these and you will have eliminated everything on your side.

When is it Airalo's problem, not yours?

Sometimes you have done everything right and it still fails. That is Airalo's side, and it is fair to say so:

• The eSIM never activates despite being in the destination and in coverage.
• The partner network is genuinely down or has no usable signal where their coverage map claims it does.
• The plan shows data remaining but throttles or drops repeatedly.

At that point contact Airalo support through the app - they run 24/7 chat - and describe exactly what you tried. If they cannot restore service, their refund terms may apply, though as of 2026 you should check Airalo's current help center for the exact conditions, since policies change and partial-use plans are usually only refunded for the unused portion.

To be fair to Airalo: it runs the widest eSIM catalog in the business and reaches destinations most rivals skip, so for obscure countries it is often the only practical option. But if an Airalo eSIM has failed you on coverage or left you waiting on slow support more than once, it is reasonable to try a more transparent provider next time. That is where something like eSIMpass fits: fixed-data plans from €3.07, a live "My eSIMs" dashboard that shows your data burning down in real time so a "not working" plan is never a mystery, and real top-up instead of rebuying. It is a smaller brand with a narrower catalog for very unusual destinations, so this is a genuine try-it, not a blanket "switch everything" - an eSIM is just a profile you scan in, so it costs nothing to test.

The bottom line

Nine times out of ten, an Airalo eSIM that is not working is a settings issue, not a broken product: turn on data roaming for the eSIM line, set it as your data line, and enter the APN if one was provided. Confirm you are activated and in coverage, run the airplane-mode-and-restart reset, and only then treat it as Airalo's problem and open a support ticket. Fix the settings first, and you will usually be online in a couple of minutes.

Why does my Airalo eSIM say "No Service"?

Usually because data roaming is off for the eSIM line, or the eSIM has not activated yet because you are not in the destination or not in the partner network's coverage. Turn on data roaming for the Airalo line, make sure it is your selected data line, and if you have arrived at your destination, restart the phone and give it a few minutes to register.

Do I have to turn on data roaming for an Airalo eSIM?

Yes, in almost every case. A travel eSIM connects to a local partner network, which your phone counts as roaming, so the data will not flow with roaming off. On iPhone you enable it per line, so you can leave roaming off for your home SIM and only turn it on for the Airalo eSIM.

What APN do I use for my Airalo eSIM?

Airalo provides the correct APN in the installation instructions inside its app, and for most plans it is applied automatically. Do not guess or copy an APN from another provider. If your plan needs one, enter Airalo's stated value exactly, leaving username and password blank unless told otherwise.

My Airalo eSIM installed but has no internet - what now?

Check three things in order: data roaming is on for the eSIM, the eSIM is set as your data line, and the APN matches Airalo's instructions. Then toggle airplane mode for ten seconds, restart, and confirm you still have data left in the app. If it still fails while you are in coverage, contact Airalo support.

Can I get a refund if my Airalo eSIM never works?

Possibly, if Airalo cannot restore service. Contact their support first so they can try to fix it, then ask about a refund. As of 2026, check Airalo's current help center for exact terms, since refunds are typically limited (for example, partial-use plans usually only refund the unused portion).
