Airalo eSIM Not Working? Quick Reconnection Guide [2026]

Airalo eSIM Not Working? Quick Reconnection Guide [2026]

Marco Bianchi — frequent international traveler, dual-SIM iPhone on a European carrier. Procedure tested first-hand on iPhone 14 Pro (iOS 17.5) and Samsung Galaxy S23 (Android 14, One UI 6.0). Xiaomi procedure cross-checked against MIUI 14 / HyperOS menus. Last tested: May 2026.

You just landed, waited 90 seconds, and the status bar says "Emergency Calls Only" or "No Service" on the Airalo line. Don't panic. In 70% of cases it's one thing — the "Data Roaming" toggle — and it's a 30-second fix. In the remaining 30%, there are 4-5 possible causes and an orderly procedure to rule them out. Below you'll find the quick checklist, the procedure for iPhone, Samsung , Xiaomi, the country-specific cases for China/USA/Japan, and — when all else fails — the right moment to write to support.

60-second quick check

TL;DR — Why my Airalo eSIM isn't working: The three causes in order of probability are: (1) the "Data Roaming" toggle is off on the Airalo line — the cause in 70% of cases (alanfibra, fibraforum post 43); (2) the phone is locked onto a carrier with weak coverage and you need to force manual selection (charlisto, post 42); (3) APN not configured or eSIM profile corrupted. Procedure: Settings > Cellular > Airalo line > Data Roaming = ON, wait 30-90 seconds.

Open your phone and run these checks in the order shown. They're ordered by probability: stop at the first thing that works.

1. Airplane mode ON for 30 seconds, then OFF. Forces the phone to reconnect to the network. Works in ~30% of cases but not always — move to step 2 if the bar stays empty.
2. Data Roaming ON on the Airalo line. iPhone: Settings > Cellular > [Airalo line] > Data Roaming = ON. Samsung: Settings > Connections > SIM Manager > [Airalo line] > Data Roaming = ON. Xiaomi: Settings > SIM Cards > [Airalo line] > Data Roaming = ON. Works in ~50% of cases.
3. Cellular Data line = Airalo. Verify that the default line for cellular data is actually Airalo, not your home line. iPhone: Settings > Cellular > Cellular Data = [Airalo line]. Works in ~10% of cases.
4. Plan active in the Airalo app. Open the Airalo app > My eSIMs > [your eSIM] > Details. Status must say "Active" (with day countdown). If it says "Pending", you haven't consumed the first byte yet; if it says "Expired", you need to buy a new plan.
5. Manual carrier selection. If the phone has latched onto a carrier with weak coverage, force it. Procedure below.
6. Reinstall the eSIM. If none of the steps above work, uninstall the eSIM from the phone and reinstall it from the Airalo app via "Reinstall eSIM".
7. Contact Airalo support. If you've exhausted everything, message via in-app chat with screenshots. Full procedure in the dedicated section.

Have you enabled data roaming?

TL;DR — Do I need to enable data roaming for Airalo: Yes, on the Airalo line. Even though the eSIM piggybacks on the local carrier in your destination country, the phone classifies that line as "roaming" and blocks data without the toggle active. It's the number one cause of "Airalo not working" in 70% of cases (alanfibra, fibraforum post 43). On your home line, instead, TURN OFF data roaming so you don't get charged anything by your home carrier.

Let me quote the community voice that first asked this question, which I cite because it's the first thing users ask anyone who writes "Airalo won't connect":

"Have you enabled data roaming?" — alanfibra, fibraforum post 43

This sentence is the number one cause of "Airalo not working". Let's explain why.

The technical issue. Even though your Airalo eSIM is a SIM from the local carrier in the country you're in (Turkcell in Turkey , AT&T in the USA, Vodafone Egypt in Egypt, NTT Docomo or KDDI in Japan), from the phone's point of view "it's not your primary home SIM". The operating system classifies any connection on a line that isn't the primary set one as "roaming". The "Data Roaming" toggle authorizes the line to connect to the data network. Without it, you've installed the eSIM and you've paid, but the phone refuses to download a single byte.

Procedure by device:

iPhone (iOS 17 and iOS 18)

1. Settings > Cellular.
2. Tap the line labeled "Airalo" (or whatever you named it: "USA Data", "Airalo Turkey", etc.).
3. Data Roaming: turn the toggle ON (green).
4. Also verify: this same Airalo line must be selected as "Cellular Data" line on the main Cellular screen.
5. On your home line, instead, turn off the "Data Roaming" toggle — so you don't pay anything to your home carrier.

Samsung Galaxy (Android 13+, One UI 5/6)

1. Settings > Connections > SIM Manager.
2. Tap the Airalo line.
3. Data Roaming: turn the toggle ON.
4. Going back to Connections > Mobile Networks, verify that the Airalo line is selected for "Mobile Data".

Xiaomi (MIUI 14 / HyperOS)

1. Settings > SIM Cards & Mobile Networks.
2. Tap the Airalo line.
3. Data Roaming: ON.
4. In Settings > SIM Cards > Mobile Data = Airalo line (explicit selection).

Check done. Now airplane mode ON for 30 seconds, then OFF. If the status bar shows the name of a local carrier (e.g. "merhaba" in Turkey, "AT&T" or "Cellular Connect" in the USA, "vodafone EG" in Egypt ) on the Airalo line, you've fixed it.

Have you tried selecting the carrier manually?

The second community voice worth quoting verbatim as an H2:

"have you also tried selecting the carrier manually?" — charlisto, fibraforum post 42

This procedure fixes the case where the phone has latched onto a carrier with weak coverage in the area, even though there's good coverage from another carrier with which the Airalo eSIM has a roaming agreement.

When you need it. You see the signal bar with 1-2 bars, run a speed test that gives laughable speeds, yet you're downtown. Probably you're latched onto a secondary network. Force manual selection and choose a primary carrier.

iPhone

1. Settings > Cellular > [Airalo line] > Network Selection.
2. Turn off "Automatic" (toggle at the top).
3. Wait 10-15 seconds: the iPhone scans available networks.
4. Pick a carrier from the list. For the country you're in, the "primary" carrier is usually the one with the largest name in the list (e.g. in Turkey: Turkcell. In USA: AT&T or T-Mobile. In Egypt: Vodafone EG. In Japan: NTT DOCOMO or KDDI).
5. Wait 30 seconds: the phone re-registers. If the bar says the name of the carrier you chose, you've fixed it.

Samsung Galaxy

1. Settings > Connections > Mobile Networks > Network Operators.
2. Turn off "Select Automatically".
3. Wait for the scan, then pick the carrier manually.

Xiaomi

1. Settings > SIM Cards & Mobile Networks > [Airalo line] > Preferred Network Selection.
2. Change from "Automatic" to "Manual".
3. Pick from the list.

Traveler's tip. If you see several carriers in the list and don't know which to pick, the Airalo app on the plan page often specifies the "carrier" the eSIM piggybacks on. Example: Turkey "merhaba" plan piggybacks on Turkcell — pick Turkcell. USA "Change" plan piggybacks on AT&T — pick AT&T.

Verify APN and data profiles

The APN (Access Point Name) is the "gate" the phone uses to connect to the data network. In most cases it's configured automatically on first connection. In some cases (eSIM reactivated after a long period, corrupted data profile, country with non-standard APN), you need to enter it manually.

How to find the APN for your Airalo plan. Open the Airalo app > My eSIMs > [your eSIM] > Details. Scroll to "eSIM Data" or "APN Settings". There you'll find the plan-specific APN (e.g. "internet" for most plans, but for some countries it can be "data.airalo.com" or a custom APN from the local carrier).

iPhone

1. Settings > Cellular > [Airalo line] > Cellular Data Network.
2. "Cellular Data" section:
3. Username, Password: leave empty (usually).

Save and go back.

Android (Samsung / Xiaomi / generic)

1. Settings > Connections (Samsung) or SIM Cards (Xiaomi) > Mobile Networks > APN > Add.
2. Fill in:
3. APN: as shown in the Airalo app.
4. APN type: "default,supl,mms" (or leave "default" if it doesn't work).

Save. Go back to the APN list and select the one you just created.

Network reset and reboot: when it really works

TL;DR — How to reset an Airalo eSIM: Standard procedure in three steps: airplane mode ON for 30 seconds then OFF; full phone reboot (press side button + volume up, slide Power Off); if still nothing, Settings > General > Transfer or Reset > Reset > Reset Network Settings (requires WiFi password). If the plan shows active in the Airalo app but the phone isn't connecting, the definitive fix is to uninstall the eSIM and reinstall it via "Reinstall eSIM" in the app.

The three reset levels, in order of invasiveness:

Level 1 (1 minute). Airplane mode ON 30 seconds → OFF. Forces the phone to redo the network registration procedure. Fixes ~30% of remaining cases.

Level 2 (3 minutes). Full phone shutdown. Wait 30 seconds. Power back on. Fixes ~50% of remaining cases (cumulative with level 1).

Level 3 (5 minutes, you lose WiFi passwords). Network settings reset. iPhone: Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. Android Samsung: Settings > General Management > Reset > Reset Network Settings. Xiaomi: Settings > Connect & Share > Reset Network Settings. Warning: you lose saved WiFi passwords and will have to re-enter them (note your important PINs first).

Level 4 (10 minutes, last resort). Uninstall the eSIM from the phone, then reinstall it from the Airalo app. iPhone: Settings > Cellular > [Airalo line] > Remove eSIM. Then open the Airalo app > My eSIMs > [your eSIM] > Reinstall eSIM > follow the QR procedure as you did the first time. The data plan and the remaining days countdown stay unchanged.

When to contact Airalo support

TL;DR — Can I reinstall a deleted Airalo eSIM: Yes. Open the Airalo app > My eSIMs > tap the eSIM > "Reinstall eSIM". The app generates a new QR and a new installation procedure. The data plan and the remaining days countdown stay unchanged: you're just reinstalling the profile. If "Reinstall" doesn't appear, message Airalo support via in-app chat — CosimoP's case (fibraforum post 41 → 44) was resolved via chat in English.

If you've done all four reset levels, you've verified data roaming ON, you've forced manual selection, you've checked the APN, and still nothing, it's time to write to Airalo support. The good news: they respond, and they fix things.

CosimoP (fibraforum post 41) describes the first moment, the "not working" one:

"I'm having problems instead, eSIM registration and APN OK but it won't register on the network, I only have emergency calls. I'll have to test customer service (and do 7 hours of driving with no connection, lucky I downloaded the offline maps here at the airport)" — CosimoP, fibraforum post 41

Three days later, post 44:

"Yes I had tried all the things written in the guide. In the end, support after asking me for various screens invited me via chat to try again and the situation unblocked. I don't know exactly what they did but it worked and top responsiveness so Airalo recommended 💪." — CosimoP, fibraforum post 44

How to write to support effectively:

1. Open the Airalo app > Help / Support > Chat.
2. Prepare these 4 screenshots in advance:
3. Settings > Cellular screen with the Airalo line and the "Data Roaming" toggle active.
4. "Network Selection" screen with the selected carrier.
5. Phone status bar showing the carrier name (or "Emergency Only").

Write in concise English. "Hi, I'm in [country]. eSIM [plan name] activated, roaming data ON, manual operator selected, still 'No service'. Screenshots attached. Please help."

Wait. Typical reply within 30 minutes during US business hours, 2-4 hours otherwise. They almost always resolve.

Country-specific cases

Three countries need a separate note because they have structural network issues that change the standard troubleshooting procedure.

China — the firewall and VPN

Airalo China piggybacks on local carriers via roaming agreement. It technically works, but the Chinese "Great Firewall" blocks Google, WhatsApp, Instagram, YouTube, Telegram at the network level. If your Airalo eSIM connects but your apps don't work, it is NOT Airalo that's broken — it's China. The solution is a VPN activated BEFORE entering China.

For the detail: China: VPN and firewall (specific case) .

USA — network aggregation

Airalo USA piggybacks on AT&T via the "Change" brand (and some plans aggregate with T-Mobile). In the US, the specific phenomenon is that Verizon, T-Mobile and AT&T use different frequencies, and in rural zones one carrier covers where another doesn't. If your Airalo eSIM "isn't working" in a specific US area, try manual carrier selection and switch between AT&T, T-Mobile, Verizon. Coverage often returns by switching networks.

For the detail: USA: Verizon / T-Mobile / AT&T network aggregation .

Japan — Ubigi-Airalo coexistence

Japan is peculiar because many travelers installed Ubigi before Airalo, and the two eSIM profiles can conflict if both are active on the same line. If you have Ubigi installed from a previous trip, uninstall it before activating Airalo, or make sure they are on separate lines. alanfibra (fibraforum post 21) also recalls a case of 5G not working with Airalo where MobiMatter did have 5G — the same caveat applies to Japan in zones where NTT Docomo offers native 5G that Airalo roaming may not aggregate.

For the detail: Japan: Ubigi-Airalo coexistence .

A note on "automatic activation"

alanfibra (fibraforum post 39) explains a detail that prevents many panic attacks on the first trip: "the plan activates once connected to the internet." It means that your Airalo eSIM installed at home is "dormant". The day countdown and GB consumption start ONLY when the phone makes the first data connection in the destination country. If you're at home and you see "Pending activation" on the Airalo app, it's normal — it's not an error.

Frequently asked questions

Why isn't my Airalo eSIM working? Three causes in order of probability: (1) "Data Roaming" toggle off on the Airalo line (~70% of cases); (2) phone latched onto a weak network (~15-20%); (3) APN not configured or eSIM profile corrupted (~10%).

How do I reset an Airalo eSIM? Airplane mode ON 30s → OFF, phone reboot, network settings reset (you lose WiFi passwords), reinstall the eSIM from the Airalo app via "Reinstall eSIM".

Can I reinstall a deleted Airalo eSIM? Yes. Airalo app > My eSIMs > [your eSIM] > Reinstall eSIM. It generates a new QR. The plan and countdown stay unchanged.

Do I need to enable data roaming for Airalo? Yes, on the Airalo line. Even though the eSIM piggybacks on the local carrier, the phone classifies that line as "roaming". On your home line, TURN OFF data roaming so you don't get charged anything by your home carrier.

How do I manually select the carrier on Airalo? iPhone: Settings > Cellular > Airalo line > Network Selection > Automatic = OFF, then pick. Samsung: Connections > Mobile Networks > Network Operators. Xiaomi: SIM Cards > Airalo line > Preferred Network Selection > Manual.

Is the Airalo APN already configured? In most cases yes. If you need to enter it manually, get the parameters from the Airalo app > My eSIMs > Details.

When should I contact Airalo support? After verifying data roaming ON, manual selection, APN, reboot, eSIM reinstallation. Prepare screenshots, write in concise English via in-app chat.

Airalo won't register on the network: what to do? Four steps: plan active in the app, data roaming ON, manual carrier selection, reinstall eSIM. If still "Emergency Only", contact support with screenshots.
