Overview
Berk Bayraktar founded Esimatic in 2023. It's based in Riga, Latvia. On the App Store, its developer entity is listed as 'eSIM SIA'. SIA is the standard name for a Latvian limited-liability company. Third-party review sites record the brand as chosen 13,095 times, with a 4.5-star average. Esimatic's own iOS app listing shows a separate 4.5-out-of-5 rating, from 22 App Store ratings.
Like other independent eSIM retailers, Esimatic doesn't run its own network. It sources data from partner mobile networks in each destination instead. The company describes this as partnering with 'top-tier networks' for strength and speed. Its catalogue covers around 200 countries. That includes local, regional (with CENAM and CIS bundles) and global plans. You buy everything through the app. It also runs a loyalty cashback programme and a $3 referral reward.
Coverage on a cruise
Esimatic's eSIMs are ordinary land-based data plans. The company's own marketing talks about partnering with local mobile networks. It never mentions any satellite or maritime service. Nothing in the material reviewed suggests coverage beyond a normal cellular footprint. Like any shore-based network, its signal only reaches so far. It stops getting to a ship at about 12 nautical miles offshore. That means it won't work through a sea day, whichever plan or country you bought. The hotspot bundled with the unlimited plans only helps while you're docked at a port, within range of the local carrier. Once the ship heads back to sea, it goes quiet too.
Plans and pricing
Esimatic's data starts from around $3.18 for a small local allowance. Regional bundles cost roughly $0.75 per gigabyte. The largest tiers offer quotas as high as 200GB. Validity runs for up to 30 days (checked September 2026, via third-party review). The app also offers 'Day Plan' and 'Day Plan+' options, priced by the day. Unlimited-data plans run from 1 to 30 days, with hotspot access included.
You don't need any ID or KYC check to buy a plan. The app also has a tiered loyalty-cashback programme, plus a $3 credit for successful referrals. Third-party review coverage says you can add a top-up to an existing eSIM. You won't need a fresh install. That wasn't independently confirmed on the company's own site, though. That same third-party test measured customer service response times too. Live chat replies took roughly 1 hour 18 minutes. That's slower than the near-instant WhatsApp replies some rival resellers offer.

Setup and activation
You buy and manage Esimatic mainly through its own app. Pick a plan, pay, then scan the QR code it generates to install the eSIM profile. That step needs an internet connection, so do it on home Wi-Fi before your cruise departs. The app then tracks your data use in real time. You can add a top-up without reinstalling. That means you can top up the same profile again at a later port. No need to buy a fresh eSIM each time.

Cruise and ferry plans
The plans database on this site holds cruise, ferry and maritime products only. Esimatic publishes none, so there is no plan table on this page. Its regional data plans remain the relevant purchase for port days.
Verdict
Esimatic offers a wide range of plans, hotspot-enabled unlimited tiers and no ID check at checkout. That makes it a flexible port-day option if you want one app for many destinations. It has a 4.5-star rating, though from a fairly modest review base. There are also scattered reports of dropped connections. It's worth checking current reviews for your specific port. Do that before you rely on it as your only data source there. That matters most on a short call, when you won't have much time to troubleshoot.
What to pair this with for sea days

Frequently asked questions
01Does Esimatic work on a cruise ship?+
In port, yes. At sea, no. Esimatic sells terrestrial travel data; the ship's own maritime network is a separate system that only GigSky, Saily and Maya sell access to. You want one of each.
02Who founded Esimatic and where is it based?+
Berk Bayraktar founded Esimatic in 2023. It's based in Riga, Latvia. On the App Store, its developer entity is registered as 'eSIM SIA' (checked September 2026).
03Does Esimatic require identity verification to buy a plan?+
No. Third-party review coverage says the purchase process needs no KYC or ID check. That's in line with most prepaid travel-eSIM retailers. You typically just need a valid payment method and an eSIM-capable phone.
04Can an Esimatic plan be topped up instead of buying a new eSIM?+
Yes, according to third-party review coverage. You can add extra data to an existing Esimatic eSIM without a fresh install. That lets you reuse the same profile at a later port. No need to install a new eSIM each time. This wasn't independently confirmed on the company's own site.
05How fast does Esimatic respond to support queries?+
A third-party test recorded a live-chat response time. It came to roughly 1 hour 18 minutes (checked September 2026). That's noticeably slower than the near-instant WhatsApp replies some rival resellers offer. It's worth factoring in if your plan needs troubleshooting during a short port call.
06Is there a Esimatic discount code?+
Yes — ESIMDUDE0. Discount on Esimatic plans with code ESIMDUDE0 Paste it into the promo box at checkout before paying. If the total does not move, the code has lapsed and should be reported so it can be pulled from this page.
