Airalo vs AeroSims for Turkey (2026): 5 GB a Day vs 3 GB — and the Real Price Math
Airalo vs AeroSims for Turkey (2026): 5 GB a Day vs 3 GB — and the Real Price Math
Updated July 2026 · Prices verified at provider checkouts and subject to change
Airalo practically invented the travel eSIM store; AeroSims is the specialist that sells Turkey data by the day. Both will have you online before you clear passport control at Istanbul Airport — but they price Turkey very differently, and their “unlimited” plans hide different numbers. We put both through the same checkout in July 2026 so you can decide in two minutes.
The quick verdict
Pick AeroSims for most Turkey trips. At $21.32 for 7 days ($3.05/day) it undercuts Airalo’s $27.00 unlimited by about 21% — and it gives you 5 GB per day at full speed versus Airalo’s 3 GB: two-thirds more high-speed data, every single day. You also buy any duration from 1 to 90 days instead of choosing from six fixed plans.
Pick Airalo if you’re settling in for 15–30 days on unlimited and want the lowest sticker price: its 15-day ($39.00) and 30-day ($69.00) plans cost less than AeroSims’ — as long as 3 GB/day at full speed and 1 Mbps afterwards fit your usage. Its app and 200-country catalog are genuinely polished, too.
Light user? Skip unlimited entirely: AeroSims’ fixed Turkey data packages run from $2.90 for 3 GB to just $6.90 for 10 GB (valid 30 days) — less than half of Airalo’s $15.50 for the same 10 GB.
| 7-day Turkey | AeroSims | Airalo |
|---|---|---|
| Price (7 days) | $21.32 | $27.00 |
| Price per day | $3.05 | ~$3.86 |
| High-speed allowance | 5 GB/day — stated openly | 3 GB/day |
| After the cap | Reduced until midnight | 1 Mbps |
| Trip lengths | Any 1–90 days | 6 fixed plans (3–30 days) |
| Network | 3 networks (Turkcell · Vodafone · Türk Telekom) | Türk Telekom · 4G/5G |
| App required | No — QR by email | Account required · app-centric |
| Money-back | 30-day guarantee | Case-by-case via support |
The price gap, in real trips
For the classic one-week Istanbul-and-Cappadocia loop, AeroSims charges $21.32 against Airalo’s $27.00 — a saving of $5.68, or about 21%. The pattern holds across every short-trip length Airalo offers: 3 days costs $9.53 vs $11.50, 5 days $15.55 vs $18.50, and 10 days $29.48 vs $34.50 (all prices as of July 2026). Day for day on a week-long trip, that’s $3.05 versus roughly $3.86.
Stay longer and the tables genuinely turn — on sticker price. Airalo’s 15-day unlimited is $39.00 to AeroSims’ $41.80, and its 30-day plan is $69.00 to $77.15. If a month of 3 GB per day suits you, Airalo is the cheaper unlimited there, and we’d rather tell you that than pretend otherwise. But look at what the extra ~$8 buys on the 30-day AeroSims plan: a 5 GB daily allowance instead of 3 GB — up to 150 GB of full-speed data in a month versus 90 GB — plus day-exact durations. An 11-day trip on Airalo means paying for the 15-day plan; AeroSims sells you exactly 11 days.
And that’s before the comparison every traveler should actually make: if your usage is normal — maps, WhatsApp, social, photos — a fixed 10 GB package for $6.90 covers a typical two-week Turkey trip for a quarter of any unlimited plan’s price. Turkey is one of AeroSims’ cheapest destinations per gigabyte, full stop — see where it sits in the eSIM Price Index 2026.
“Unlimited” fine print: 5 GB a day vs 3 GB a day
Every unlimited travel eSIM has a fair-use policy — the difference is what the number is. To Airalo’s credit, its Turkey model is public: unlimited plans run at full speed for 3 GB per day, then drop to 1 Mbps until the next day. AeroSims states its number openly too, and it’s higher: 5 GB per day at full 4G/5G speed, reduced afterwards until midnight. Neither is infinite; the honest question is which ceiling you’d actually hit.
For perspective, 3 GB is roughly three to four hours of HD streaming, or one serious end-of-day backup of photos and video; 5 GB is closer to six hours of HD video or a full day of heavy navigation, uploads and video calls. Most travelers use 1–2 GB per day and will never feel either cap — but the days you do feel it are exactly the memorable ones: uploading hot-air-balloon footage from Göreme, or video-calling home from a coast hotel with weak Wi-Fi. At 1 Mbps, maps and WhatsApp keep working; video calls and streaming get painful.
Fixed-GB face-off: Merhaba vs AeroSims packages
Fixed-GB plans have always been Airalo’s home turf — its Turkey line (“Merhaba”) starts at $4.00 for 1 GB over 3 days. But line the two catalogs up at the sizes travelers actually buy, all with 30-day validity, and the gap is stark (as of July 2026):
| Data (30 days) | AeroSims | Airalo | You save |
|---|---|---|---|
| 5 GB | $4.90 | $10.00 | 51% |
| 10 GB | $6.90 | $15.50 | 55% |
| 20 GB | $13.90 | $22.50 | 38% |
| 50 GB | $30.90 | $34.50 | 10% |
Long-stay travelers see the widest gap of all: AeroSims sells 50 GB valid 180 days for $33.90, while Airalo’s only 180-day Turkey option is 100 GB for $185.00 — that’s $0.68 per gigabyte versus $1.85. Every size lives on one page: AeroSims Turkey data packages.
Buying and support: QR by email vs app ecosystem
AeroSims delivers your QR code by email within seconds of checkout — no app, no account needed — and backs every purchase with a 30-day money-back guarantee. Airalo’s flow centers on its (genuinely good) app: create an account, buy, install and track usage there, with a 200-plus-country catalog and Airmoney loyalty credit for future trips. Refunds at Airalo are handled case-by-case through support rather than as a blanket guarantee. Neither approach is wrong — one optimizes for speed to getting online, the other for managing many trips in one place.
Why not just buy a SIM at Istanbul Airport?
Turkey’s airport SIM counters are famously the most expensive in Europe’s neighborhood — tourist bundles at IST and Sabiha Gökçen commonly run €25–35 for a handful of gigabytes, physical SIMs require passport registration, and the queue lands right after a long-haul flight. Either eSIM in this comparison costs a fraction of that and is working before you reach baggage claim. (Staying months? Turkey’s IMEI-registration rule applies to foreign phones on local SIMs — a travel eSIM sidesteps that entirely for normal trips.)
Coverage: Istanbul to the coast
The AeroSims Turkey eSIM connects to Turkcell, Vodafone Türkiye and Türk Telekom, switching automatically to the strongest signal; Airalo’s Turkey plans connect via Türk Telekom only. All are proper national networks with 4G everywhere tourists go and 5G in the big cities: Istanbul, Ankara, Izmir, Antalya, Bodrum and the Cappadocia region are solid on either eSIM, with thinner signal only in the remote eastern highlands. In practice coverage is close — the multi-network fallback mainly helps off the beaten path — so decide on price and daily allowance, not on signal bars. Hot-air balloon selfies from Göreme upload just fine on both.
Turkey eSIM questions travelers ask
Is AeroSims really cheaper than Airalo for Turkey?
For trips up to 10 days, yes — about 15–21% on unlimited ($21.32 vs $27.00 for a week) and less than half price on fixed packages (10 GB: $6.90 vs $15.50). Airalo’s 15- and 30-day unlimited plans are the exception: lower stickers ($39.00 / $69.00), but with a smaller 3 GB daily allowance.
Does Airalo have truly unlimited data in Turkey?
No provider does. Airalo’s “unlimited” Turkey plans give 3 GB per day at full speed, then 1 Mbps. AeroSims gives 5 GB per day, reduced after that until midnight. The difference isn’t whether a ceiling exists — it’s how high it sits and how clearly it’s stated before you pay.
What does “5 GB/day at full speed” mean in practice?
Each day you get 5 GB at full 4G/5G speed; beyond that, speed is reduced until the next day. Most travelers use 1–2 GB per day, so the limit is rarely felt — the point is that you know the number before you buy.
Do I need a passport for an eSIM in Turkey?
No. Passport registration applies to physical SIM cards bought in Turkey. A travel eSIM — from either provider — needs no ID.
Does my WhatsApp number keep working?
Yes, on both. These eSIMs are data-only; your home SIM stays installed for calls and SMS codes, and WhatsApp keeps your existing number.
When does the AeroSims plan start counting days?
When the eSIM first connects to a Turkish network — not at purchase. Install it at home days before you fly and lose nothing.

Bottom line
Airalo is the giant of fixed-GB eSIMs, and for a 15–30-day unlimited stay its sticker price is genuinely lower. But for the trips most people actually take to Turkey — a week, ten days — AeroSims costs about a fifth less, gives you two-thirds more daily high-speed data (5 GB vs 3 GB), publishes that number up front, and lets you buy exactly the days you need. And if you’d rather not pay for unlimited at all, its $6.90 10 GB package has no answer in Airalo’s Turkey catalog. For Turkey in 2026, that’s the rational pick.
