You bought an Airalo eSIM, installed it, enabled data roaming like the guide says, and now your phone connects but stubbornly stays on 4G LTE. 5G won't connect. Maybe you're in an area where TIM and Vodafone show "5G" in the status bar on your friends' devices. Your Airalo line doesn't. That symptom is exactly what alanfibra described on the main Italian forum (fibraforum thread 42484, post 21): *"With Airalo, even though TIM and Vodafone in the area had 5G, it wasn't working, unlike MobiMatter which worked on 5G."*
You're not alone. And here's the surprise: it's not always your fault or your iPhone's. Sometimes it's a provisioning decision on Airalo's end, and that needs to be said straight. Below you'll find the 3 real causes, a decision tree to pinpoint where your problem is, a country-by-country table of where Airalo actually offers 5G, and when it makes sense to switch to MobiMatter like alanfibra did. No fluff.
TL;DR — Why Airalo Won't Connect to 5G (3 Most Common Causes)
TL;DR — Why Airalo won't connect to 5G:Three causes, in order of frequency. (1) Your iPhone is set to LTE or 5G Off on the Airalo line — go to Settings > Cellular > Airalo line > Voice & Data and select 5G Auto. (2) The Airalo plan in your destination country doesn't include 5G in the agreement with the partner carrier — this happens in Turkey, Egypt, and Morocco. (3) The area is covered by NSA only while the Airalo carrier is looking for SA. Always check the iPhone setting first — it's the #1 mistake.
But there's one absolute prerequisite that needs to be addressed first. The Data Roaming toggle on the Airalo line must be ON. If it's not, you'll get neither 5G nor 4G — the phone won't connect at all. First check: did you enable data roaming? (prerequisite pillar) — head to the main guide and come back here only if that toggle is already ON.
Symptom: Airalo Connected on 4G, Want 5G — Quick Check
TL;DR — Airalo on 4G but not 5G, what to check:In order: (1) Settings > Cellular > Airalo line > Voice & Data set to 5G Auto, (2) Data Roaming ON on the Airalo line, (3) confirm the area actually has consumer 5G coverage (nperf.com or a nearby device showing "5G"), (4) wait 5 minutes — the modem latches onto LTE first for stability and then negotiates the handoff to 5G. If all 4 checks pass and you're still on 4G, scroll down to the decision tree.
If you're mid-trip reading this page with your phone in hand showing "4G" or "LTE" next to the Airalo carrier name, run these 4 checks in 90 seconds:
- iPhone 5G mode set to Auto.Settings > Cellular > Airalo line > Voice & Data. It must say "5G Auto" — not "LTE" and not "5G Off".
- Data Roaming ON on the Airalo line.Still in the Airalo line submenu. Without this, no connection and no 5G.
- Are you actually in a 5G area?Open nperf.com on Wi-Fi (or ask a friend with a local carrier if they see "5G"). If no carrier shows 5G in the area, the problem isn't Airalo — it's coverage.
- Wait 5 minutes.The modem latches onto LTE first for stability, then (if the network supports it) negotiates the switch to 5G NSA. It's not always instant.
Diagnostic decision tree (4-step flowchart)
When the basic settings check out, the problem could be in 4 different places. Diagnose them in order — each level rules out the next.
Step (a). Is your iPhone 5G-capable?Only iPhone 12 and later support 5G. iPhone 11, XR, XS, X, and older are 4G LTE-max — even with an Airalo eSIM, the issue isn't Airalo, it's the phone. Check your model at Settings > General > About > Model Name. If you have an iPhone 11 or older, you will never connect to 5G — on Airalo or any other carrier. Full stop.
Step (b). Is the Airalo plan you purchased 5G-enabled?Open the Airalo app > My eSIMs > tap the active plan. Scroll through the plan page. If Airalo includes 5G for that country, it says so in the plan specs (e.g., "5G/4G/LTE network"). If it only says "4G/LTE network", the plan doesn't include 5G — a commercial decision by Airalo — even if your phone and the country's network support it.
Not even activating on 4G? Activation symptom guide . 5G requires the eSIM to have at least registered on 4G first — if you're seeing "No Service", start with the activation guide.
Step (c). Does the country have 5G coverage where you are?Different from point (b) — this is about the physical reality of the country. The USA, Japan, South Korea, urban Germany, and urban Italy have widespread 5G. Turkey launched commercial 5G in mid-2025, but coverage is still patchy — mainly Istanbul and Ankara. Egypt, Morocco, Tunisia, Algeria, Albania, and North Macedonia don't have consumer 5G yet. If you're in a country without active consumer 5G, Airalo isn't the problem — there's simply no 5G to latch onto.
Step (d). Is the iPhone 5G mode set correctly?This is where 90% of users who land on this page go wrong. Go to Settings > Cellular > tap the Airalo line > Voice & Data. If you see "LTE" selected (not "5G Auto"), you found the culprit. Tap "5G Auto" and wait 60 seconds. The status bar should switch to "5G" if the network and plan support it. If it still doesn't, you're in the rare case where the problem is genuinely on Airalo's end — keep reading.
iPhone 5G Mode: Auto vs. On vs. Off
TL;DR — Auto, On, or Off: which 5G mode should you pick:5G Auto in 95% of cases. Auto lets the iPhone decide when to connect to 5G based on signal and quality, falls back to 4G when 5G is unstable, and saves battery. 5G On forces 5G even in weak areas (drains battery, constant switching). 5G Off (LTE) disables 5G entirely — makes sense if battery is a priority or 5G coverage in the country is marginal.
A dual-SIM iPhone has three 5G mode options per line. Here's a plain-English breakdown — because Apple doesn't do a great job of explaining it.
- 5G Auto.The iPhone connects to 5G when the network offers a stable signal, and falls back to 4G/LTE when 5G is too weak or unstable. Saves battery and keeps a consistent connection.The right choice in 95% of cases, including on Airalo.
- 5G On.Forces 5G whenever any signal is available, even a weak one. Sounds "better" but drains battery 20–30% faster than Auto, and in borderline areas causes constant disconnects (the modem oscillates between weak 5G and stable 4G). Only use it in areas with excellent 5G.
- LTE / 5G Off.Completely disables 5G — the line stays on 4G/LTE. Makes sense if battery life is a priority, if 5G coverage in the country is marginal, or if you want to avoid the extra power draw that 5G enables.
The exact path on iOS 17 and iOS 18:
- OpenSettings.
- TapCellular(on iOS 18 some devices label it "Cellular Data").
- Under "SIM" scroll down to theAiralo lineand tap it. Do NOT tap your primary carrier line.
- TapVoice & Datainside the Airalo line submenu.
- Three options:5G On,5G Auto,LTE. Tap5G Auto.
- Go back. Check the status bar (top right) — do you see "5G" next to the carrier name? You're done.

5G Per-Line: Mistake #2 After Data Roaming
Here's the trap that causes "Airalo won't connect to 5G" even when you think you've enabled it. A dual-SIM iPhone has a "Voice & Data" toggle — and therefore a 5G mode —for each line separately. If you tap the first line you see in Settings > Cellular, you might be changing the 5G setting for your primary SIM, not for Airalo. Result: your primary line has 5G enabled (and works fine at home), but the Airalo line is still stuck on LTE. No 5G on Airalo.
Worth repeating because it's the single most common mistake in dual-SIM after the roaming toggle: the 5G mode must be set ON THE SPECIFIC AIRALO LINE, not on your primary line. Check both.
Dual-SIM iPhone? Possible conflict . If you've set 5G Auto on both lines and the iPhone keeps defaulting to the primary line for data, there's a dual-SIM priority conflict to resolve. See the dedicated guide.
Initial iPhone setup (prerequisite) . If you've never installed the Airalo eSIM from scratch, start with the iPhone activation guide.
By Country: Where Airalo Actually Offers 5G (Table)
TL;DR — Where Airalo gets 5G and where it doesn't:USA yes (T-Mobile), Japan yes (SoftBank/NTT Docomo), South Korea yes, urban Germany yes, Italy variable (Vodafone IT). Turkey usually no (Turkcell restricts it). Egypt, Morocco, Tunisia, Albania, and the Balkans are 4G LTE only — no widespread consumer 5G yet. Table verified May 2026.
Airalo doesn't offer 5G uniformly across all countries — it depends on the agreement with the partner carrier and the physical reality of local consumer 5G coverage.

Note on Italy.On Airalo regional Europe or global plans, the Italian partner network is usually Vodafone IT, so technically 5G is available. But this is exactly alanfibra's case: "With Airalo, even though TIM and Vodafone in the area had 5G, it wasn't working" (post 21). Airalo's provisioning can restrict the 5G band even where the partner carrier offers it. Read on. [Note: this section references Italy-specific carrier context.]

Honest disclosure: Airalo limits 5G in some cases (mechanism)
TL;DR — Airalo sometimes limits 5G via MVNO contract:Airalo is an MVNO marketplace that resells capacity purchased in bulk from local carriers. The Airalo-carrier agreement determines which bands are included in the resold package. For many countries Airalo includes 5G by default; for others it doesn't — even where the carrier offers 5G to its own direct customers. It's a commercial decision, not a bug.
Worth stating plainly. The contract between Airalo and the partner carrier in a specific country determines which bands and technologies (4G LTE, 5G NSA, 5G SA) are included in the package resold to the customer. The reasons are commercial: 5G is a premium band, it costs the carrier more, and Airalo (to keep prices competitive) may choose to purchase only 4G LTE capacity in certain markets.
This is the ground truth that alanfibra nailed in their post (fibraforum 21): "With Airalo, even though TIM and Vodafone in the area had 5G, it wasn't working." The phone wasn't broken. The network wasn't missing. It's that on the Airalo plan they had active, 5G was not contractually enabled at that time, in that area, on that eSIM.
What you can do as a customer: open the in-app chat in Airalo and ask for written confirmation that plan X in country Y includes 5G. If they say no, accept the 4G LTE. If 5G should be included and it's not working, that's a valid refund case.

When It Makes Sense to Switch to MobiMatter (alanfibra defection ground truth)
The uncomfortable part — and I'll say it straight because the forum already has. If you're in a situation where (a) 5G in the area is real (verified on nearby devices with local carriers), (b) you've set your iPhone to 5G Auto on the Airalo line, (c) you've waited 30 minutes after landing, and (d) Airalo stays on 4G LTE — then the practical recommendation from the community is MobiMatter.
alanfibra puts it plainly (fibraforum post 14): *"I used Airalo in the past and was happy with it; right now I'm using MobiMatter, I find it cheaper than the competition."* And in post 21 they nail the 5G issue: *"With Airalo, even though TIM and Vodafone in the area had 5G, it wasn't working, unlike MobiMatter which worked on 5G."* This is a documented case — a verified user experience with two eSIMs running in parallel in the same area.
That said, it's worth being precise about when to switch. MobiMatter makes more sense than Airalo specifically:
- in countries where Airalo provisioning has been reported as 4G-only but MobiMatter offers 5G in that market (urban Italy is the documented case);
- for plans 30+ days with a lot of GB, where MobiMatter has more aggressive pricing;
- for users who have already tested Airalo and hit the 5G limitation — not as a blind first choice.
MobiMatter gets 5G where Airalo doesn't — full comparison . For the full Airalo vs. MobiMatter comparison with pricing table, 5G coverage, and when the switch is worth it, see the dedicated guide.
Still on 4G — When to Contact Airalo Support
You've done everything: 5G Auto on the Airalo line, data roaming ON, waited 30 minutes, confirmed the area has consumer 5G. Still on 4G. At this point your option is Airalo support — and you want to frame it as a specific request.
What to write in the Airalo in-app chat:
- Country, area (city), and time.
- Specific plan (e.g., "Discover+ USA", "Türkiye Telin Mobile 5GB").
- Screenshots of: (a) Settings > Cellular > Airalo line > Voice & Data with 5G Auto selected, (b) status bar showing "4G" or "LTE", (c) another phone in the same area showing "5G" on another carrier.
- Ask: "Can you please confirm whether plan X includes 5G in this country, or if it's 4G LTE only in Airalo's provisioning?"
Expect a response in 5–30 minutes. In cases where 5G should be available and isn't working, Airalo sometimes re-provisions the eSIM on the server side. If the plan is 4G-only by design, they'll tell you clearly — at which point you can evaluate a refund.

Frequently Asked Questions
Why won't Airalo connect to 5G when TIM and Vodafone in the area have 5G?
Because Airalo relies on a local carrier via an MVNO agreement that can exclude 5G from the resold package. The documented case is alanfibra's (fibraforum post 21): *"With Airalo, even though TIM and Vodafone in the area had 5G, it wasn't working, unlike MobiMatter which worked on 5G."* Sometimes it's a limitation on Airalo's provisioning side — not your fault. [Note: TIM and Vodafone references are Italy-specific carrier context.]
How do I enable 5G on the Airalo eSIM on iPhone?
Settings > Cellular > Airalo line > Voice & Data > 5G Auto. The toggle is PER LINE in dual-SIM — it must be set on the specific Airalo line, not your primary line. 5G Auto is the right choice in 95% of cases.
What's the difference between 5G Auto, 5G On, and 5G Off?
Auto lets the iPhone decide based on signal and quality (recommended). On forces 5G even with a weak signal but drains battery. Off (LTE) disables 5G entirely — makes sense if battery life is a priority.
Does Airalo actually offer 5G in the USA, Japan, and Turkey?
USA yes, via T-Mobile. Japan yes, via SoftBank or NTT Docomo. Turkey usually no — mostly 4G LTE via Turkcell. Egypt, Morocco, Tunisia, and Albania are 4G LTE only.
When does it make sense to switch to MobiMatter if Airalo won't get 5G?
When you're in an area with verified 5G, you've set your iPhone to 5G Auto on the Airalo line, you've waited 30 minutes, and Airalo stays on 4G. Pattern documented by alanfibra on the Italian forum. For a structured comparison see the Airalo vs. MobiMatter guide.
What does NSA vs. SA 5G mean and why does it matter for Airalo?
5G NSA (Non-Standalone) runs on top of a 4G LTE network for the control signal — this covers 95% of countries today. 5G SA (Standalone) is pure 5G with no 4G dependency — it exists only in parts of China and in testing across Europe. iPhone defaults to NSA-prefer, so this is usually not the issue with Airalo.
Do I need to enable data roaming first to get 5G on an Airalo eSIM?
Yes. Without Data Roaming ON on the Airalo line, the iPhone won't connect even on 4G, let alone 5G. It's the first canonical question in the forum (alanfibra, post 43): "Did you enable data roaming?"
