HelloRoam sells 10 GB of Turkey data for $10.69 over 30 days on Vodafone 5G, the lowest 10 GB rate here. Ubigi, the short-stopover pick, charges $3.00 for 1 GB over 7 days. Nomad, best for a heavy-data month, lists 50 GB over 30 days at $31.00.
The order in the table below comes from one yardstick, 10 GB over 30 days
This table sorts on one number, the price of 10 GB over 30 days. It is the only plan shape all six per-gigabyte sellers publish for Turkey. HelloRoam takes the top row on that yardstick, and its Turkey eSIM runs on Vodafone 5G.
The HelloRoam Travel Data Price Index, August 2026, Turkey

Method: advertised Turkey prices in US dollars, sampled 1 August 2026 and held at 30 days in the 10 GB column so they compare. Holafly bills by the day and is not ranked per gigabyte. Jetpac is excluded: its Turkey range starts at 50 GB.
HelloRoam charges $10.69 for 10 GB over 30 days in Turkey, 17.8% less than the $13.00 that Ubigi and Nomad both ask for the same 10 GB over 30 days.
Every seller in the table, read down the ranking
1. HelloRoam: the lowest 10 GB month here, at $10.69 for 10 GB over 30 days
HelloRoam is cheapest at the compared size, by $2.31 a plan, and that gap repeats on every phone in the party. Vodafone 5G carries the profile.
2. Ubigi: the stopover rung, at $3.00 for 1 GB over 7 days
Ubigi and Nomad both list 10 GB over 30 days at $13.00, so the rung below settles second place. Ubigi charges $3.00 for a gigabyte over a week, Nomad $4.00.
3. Nomad: the lowest 50 GB month here, at $31.00 for 50 GB over 30 days
Nomad puts every fixed size above one gigabyte on the same 30-day window, starting at $6.00 for 3 GB over 30 days.
4. Airalo: the most windows at one size, from $14.50 for 10 GB over 7 days
Airalo splits the same 10 GB across three clocks: $14.50 over 7 days, $15.00 over 15 days, $15.50 over 30 days. A nine-day trip stops paying for a full month.
5. Saily: the app-first buy, at $15.99 for 10 GB over 30 days
Saily’s Turkey ladder stops at $22.99 for 20 GB over 30 days, so a 50 GB month has to come from somewhere else.
6. aloSIM: the only 2 GB plan here, at $6.00 for 2 GB over 15 days
aloSIM fills the step between one and three gigabytes. Its $16.00 for 10 GB over 30 days is the dearest of the six per-gigabyte rows.
7. Holafly: unlimited data billed by the day, at $36.50 for unlimited over 10 days
Its Turkey range is unlimited data sold by the day, from $11.90 for unlimited over 3 days to $73.90 for unlimited over 30 days. Judge it on days.
The price per gigabyte drops at every step, from 1 GB over 7 days to 50 GB over 30 days
The unit price falls at every rung of the HelloRoam ladder, where most sellers flatten out.
- $3.49 for 1 GB over 7 days, or $3.49 per GB
- $5.49 for 3 GB over 30 days, or $1.83 per GB
- $8.99 for 5 GB over 30 days, or $1.80 per GB
- $10.69 for 10 GB over 30 days, or $1.07 per GB
- $18.82 for 20 GB over 30 days, or $0.94 per GB
- $32.56 for 50 GB over 30 days, or $0.65 per GB
The trick is spotting where the curve bends. Moving from 5 GB to 10 GB costs $1.70 and doubles the data.
Coverage does not break the tie in Turkey
HelloRoam names Vodafone 5G as the host on its Turkey plans, so you know the network before you pay. No travel eSIM seller owns masts in Turkey, so every row here resells a Turkish network. That leaves price, plan size and top-up terms as the variables.
A long weekend in Sultanahmet needs less data than a two-week drive down the Antalya coast
Three or four nights in Istanbul. Ferry times, menus, photos home. That is a 3 GB over 30 days job at $5.49, or $8.99 for 5 GB over 30 days.
Ten days on the coast with a hire car. Navigation runs for hours without pausing for lunch. Take 10 GB over 30 days at $10.69.
A month working from Fethiye. Video calls change the arithmetic. Start at 20 GB over 30 days for $18.82, or $32.56 for 50 GB over 30 days.
A refill bought in Göreme lands on the profile already sitting in your phone
Running out is the cheapest failure to fix. Every HelloRoam Turkey plan accepts a top-up, with no exceptions. A refill adds data to the profile already on your handset, so there is no second QR code and no reinstall in a hotel lobby. Every plan carries a 180-day money-back guarantee.
Ubigi sells a 25 GB plan over 30 days, and HelloRoam’s ladder jumps straight past it
Now the part where HelloRoam loses, because it does.
The ladder runs 20 GB over 30 days at $18.82, then jumps to 50 GB over 30 days at $32.56. Ubigi sells the missing rung, 25 GB over 30 days at $25.00. If 20 GB is tight and 50 GB too much, Ubigi has the plan and HelloRoam does not.
Ubigi takes the smallest rung too, at $3.00 for 1 GB over 7 days against HelloRoam’s $3.49 for the same 1 GB.
Nomad’s $31.00 for 50 GB over 30 days is the lowest 50 GB price here, $1.56 under HelloRoam’s $32.56 for the same size. That 4.8% gap is level, not a win.
A Turkish prepaid SIM adds a passport check and a shop queue to day one
The alternative is a local prepaid SIM, and it is a counter transaction. You bring your passport, the shop registers the line, and part of your first afternoon goes to queueing.
This guide makes no price comparison there, because no verified Turkish prepaid tariff was available. The process is what compares. A travel e-SIM is paid for before departure and works on landing.
Turn the line on at baggage claim, days after the profile went onto the phone
Installing and activating are two steps, and the gap between them is the point.
- Check the handset supports eSIM. Most phones bought in the last few years do.
- Buy at home and install the QR code on your own Wi-Fi. Airport Wi-Fi at 6am is not a plan.
- Leave your usual SIM in place. The profile sits beside it, so your number and codes carry on.
- Land, set the Turkey profile as the data line, and switch roaming off at home.
For a trip running past Turkey, a plain-English explainer covers what to check before you pay.
The ten-day pick is 10 GB over 30 days, with a refill held in reserve
Buy 10 GB over 30 days from HelloRoam at $10.69 and stop thinking about it. It is cheapest at the compared size and tops up if you guessed low. Take Ubigi’s $3.00 for 1 GB over 7 days for a stopover. Choose Holafly at $36.50 for unlimited over 10 days only if you refuse to count gigabytes.
Shops, host networks, refills and QR setup, settled for Turkey e SIM buyers
Where can I buy an eSIM in Istanbul?
You buy an eSIM online from the provider, not in a shop, and it arrives as a QR code by email. Nothing physical changes hands, so there is no counter to find in Istanbul. Buy on home Wi-Fi, because installing needs a connection.
What network does an e SIM use in Turkey?
HelloRoam’s Turkey plans run on Vodafone 5G. Every provider in the table above resells wholesale access to Turkish networks rather than owning masts of its own. Price, plan size and top-up terms are what separate them.
Can I top up my eSIM in Turkey?
Yes. Every HelloRoam Turkey plan accepts a top-up, with no exceptions across the range. The refill adds data to the profile already installed on your phone, so you never scan a second QR code. It is safe to buy the smaller plan and add mid-trip.
Is an eSIM better than roaming for a trip to Turkey?
A travel eSIM fixes the cost before you leave, while roaming rates depend on your home tariff and arrive on a later bill. HelloRoam’s 10 GB over 30 days is $10.69, paid once. Check your contract, because roaming inclusions differ sharply by network.
Is an eSIM cheaper than a local SIM card in Turkey?
No verified Turkish prepaid price was available for this guide, so it makes no claim either way. The process is what differs. A local SIM needs your passport, a shop visit and a registration step on day one. An eSIM is live on landing.
How do I activate an eSIM with a QR code?
Scan the QR code in your phone’s mobile data settings while on Wi-Fi at home, which installs the profile. Activation is a separate switch you flip on arrival, when you set the Turkey profile as your data line. Your original SIM stays put.
