Cellesim is a travel eSIM service for people who want data the moment they land, without hunting for a shop or paying roaming rates.We cover more than 200 countries and regions, with local, regional and global plans. You buy online or in our app, receive the eSIM within a minute, and install it by scanning a QR code. Your physical SIM stays in the phone, so you keep your own number for calls and bank verification codes while your data runs on our line. Our plans are data only.Our iOS and Android apps let you buy, install, check how much data is left, and top up while you are abroad, without opening a browser. Running low on a trip is a two tap fix.We work in 31 languages, and support answers in the language you write in. Every destination page lists the local networks we connect to, so you can see the coverage before you buy, and our device checker tells you whether your phone supports eSIM at all.Returning customers earn loyalty credit, and referrals give both sides a discount. Selected plans include a free VPN.If something does not work, write to us. We would rather fix it or refund it than leave you offline.

Катерино, дякуємо, що написали — і вибачте. Ми перевірили вашу eSIM за номером замовлення. Ви маєте рацію, і провина повністю наша: картка встановилася і зареєструвалася в мережі, але за три дні через неї пройшло лише 0,13 МБ із 5 ГБ. Тобто інтернет фактично не працював жодного разу. Це не питання налаштувань вашого телефона і не ваша помилка. Ми вже повернули всю суму — 516,60 грн повертаються на ту саму картку, банк зазвичай зараховує їх протягом 5–10 робочих днів. Нічого робити не потрібно, ми зробили це самі, без вашого запиту. Ваш відгук показав нам ще дещо важливе. Ми перевірили всі активні eSIM за останні 45 днів і знайшли ще кілька карток із такою самою проблемою — люди, які нам не написали, а просто пішли. Через це ми запустили автоматичну перевірку, яка щошість годин шукає картки, зареєстровані в мережі, але без трафіку. Ваш відгук став причиною цієї зміни. Розуміємо, що роумінг від власного оператора коштував вам дорожче, і що довіру повернути складніше, ніж гроші. Якщо колись захочете спробувати ще раз, напишіть нам на [email protected] — ми подбаємо про це особисто. Команда Cellesim

Easy to use and to install would use again for short time travel Sim option
Response from CellesimAug 12, 2026
Thank you, Diana — and we're glad the install went smoothly. You've put your finger on exactly what we built this for. Short trips are where a traditional SIM makes the least sense: you queue at an airport kiosk, pay for a month you won't use, and hand over your passport for the privilege. Your Uzbekistan line was 15 days, and that's the point — you buy the trip, not the contract. If it helps for next time: we also run genuinely short options on that route, down to single-day plans, so a weekend or a stopover doesn't have to cost you a fortnight. The fifth star is still out there, and we'd like to earn it. If there was anything that could have been better — anything at all — write to us at [email protected] and it goes straight to the people who can change it. Safe travels, and thank you for taking the time. Cellesim

Thank you, Goran — much appreciated. If there's something that would have made it a five, I'd like to hear it: [email protected] reaches us directly. — Cellesim Support

Cellesim promised their eSIM would connect to Magti (georgia), on their unlimited plan, but it forced my phone onto a much weaker competitor instead. therefore bought a magti sim at Batumi and used the cellesim only for checking it (max 200 mb altogether, max 3g connection). to make the long story short: after negotiations i got the full refund i deserved. also they apologized and admitted that have full responsibility. i think that ultimately they are a learning company with positive thinking.

Hi Tommy, Thank you for this honest review — and you were right on every point. We've taken it seriously and resolved it. Coverage: Our page implied Magti coverage, but this plan runs on Silknet. That was our error, and we've corrected the labeling so no future traveler is misled. Refund: We've now refunded your order in full ($40.32), not just the partial amount — it should reach your payment method within 5–10 business days. Your review: An honest negative review should never be hard to publish. Yours is now live on our site, and we've fixed our moderation process so genuine feedback isn't held back, and we've replied to your support message directly. We're genuinely sorry for the frustration and the delay in making this right. Feedback like yours is exactly what makes us better, and we appreciate you holding us accountable. — The Cellesim Team
