Und ich bekomme angezeigt eSim installiert, habe aber keine drauf. ### 3/5 — Her ülkede kullanılamıyor *2025-06-11, version 4.4.13* Rusya listede var özellikle orası için almıştım çok seyahat ettiğim içim ama orada çalışmıyor malesef ki ### 4/5 — Gute App, aber Accountdaten sind manchmal einfach weg *2025-05-11, version 4.4.12* An sich eine sehr gute App wo auch alles super funktioniert, vor allem das Marketplace feature ist super, allerdings ist es etwas seltsam, dass man wenn man die App etwas länger nicht benutzt hat, seinen Account quasi neu einrichten muss und alle Daten und Käufe von früher weg sind. Zumindest bei mir so. ### 3/5 — Works—most of the time *2025-04-27, version 4.4.12* DENT data works pretty well in the USA. It uses Verizon by default, and T-Mobile is available as well. Data connection is fast enough for most uses when using a local connection. USA one is in northern Virginia. Some web sites, especially e-commerce sites, block access from DENT. It’s really annoying, as I have to find WiFi to visit the sites. The DENT Marketplace is more difficult to use than it needs to be. When searching for data, you can only see a subset of the available offerings, and you can’t filter by things like expiration date and price per GB. I have lots of DENTs, and the value of them varies over time. It’s really annoying when my purchasing power declines precipitously. The Marketplace always reverts to USD, and I have to change back to DENTs. The most annoying thing is that selling data often throws an error “Sorry an unexpected error occurred“ They might not expect the error, but I do. I just tried as I was writing this review, and I got the error again. I never get an error when buying data. It’s annoying, because most things work okay, but there are significant deficits in many parts of the service. ### 4/5 — Dent in Europe *2025-03-30, version 4.4.11* It's worth it for the price and tne need to have signal upon arriving in Europe. I suggest activating the signal before leaving the USA and keeping it ON, until returning to the USA. 1Gb per day is e good planning ahead, you might use less than that . love it, thanks. ### 3/5 — Como pego o numero? *2025-03-25, version 4.4.11* Bom ### 5/5 — Relatable and true to its name *2025-03-13, version 4.4.10* I’ve used several eSIMs apps, solely for the data, and I can’t stress enough how excellent this app is. It features its own currency system, but you can bypass it and change the currency option and pay in dollars(USA or CAD) or in Euros, if you only need a small amount of data and don’t use it all then you can resell sell it and get refunded in Dents. Alternatively you can save those dents and use them later to buy more data ### 5/5 — love this dent app *2025-02-17, version 4.4.9* works everywhere where i want data in a different countries or the usa very great app i recommend this app 5 stars ### 5/5 — App *2025-02-12, version 4.4.9* Good ### 5/5 — Real *2025-01-28, version 4.4.9* It actually works and it’s free ## Most critical reviews (10 lowest-rated) ### 1/5 — Unreliable! *2026-06-14, version 4.5.4* That is so unreliable app, I don’t recommend. When you need the connection most, it doesn’t work. No any prior warnings! The latest example is that the UAE was included in the list of supported countries just 2 weeks ago, no when i arrive i found out that UAE is no more supported! ### 1/5 — Cannot contact support *2026-06-11, version 4.5.4* New iPhone and I can’t download a new esim. My profile says eSIM installed but it is not installed. On the contact support page I can get through the steps but after downloading a screenshot there is no option to send. ### 1/5 — Worst app ever *2026-06-01, version 4.5.4* Tried to install esim and got stuck. Tried to contact support. App has dark patterns all over so you can never reach support. Lost my $20 purchase ### 1/5 — Not installed e sim *2026-04-29, version 4.5.3* eSIM is not appearing in iPhone 16 settings. Device shows "Set Up eSIM". Please solve me eSIM problem ### 1/5 — No data in Europe! *2025-05-10, version 4.4.12* Very poor customer service indeed no customer service.no connection in the Netherlands ### 1/5 — Kesinlikle Sağlıklı değil *2025-04-29, version 4.4.12* Uygulama hiç bir şekilde doğru çalışmıyor. ### 1/5 — Doesn’t work; don’t waste time *2025-03-30, version 4.4.11* App doesn’t work, can’t login, can’t do anything. Don’t waste your time. Pick another eSIM service that actually works. ### 1/5 — Calls don’t work *2025-03-23, version 4.4.11* I paid for a plan with calls, calls do not work at all, customer service said to press a setting which delete everything and made things worse ### 1/5 — Account creation problems *2025-03-03, version 4.4.10* When i click on accept the terms the again and again ask me for accepting terms and can’t go forward ### 1/5 — Inconsistent connection and speed. The Dent marketplace is a scam *2024-12-22, version 4.4.9* Data connection drops constantly, for no apparent reason, even when I’m not moving or crossing borders. Data speed is frustratingly unreliable, even when stationary. It’s sometimes super fast and sometimes you’re unable to load a simple webpage. And it doesn’t work with ChatGPT Dent points one can earn by watching ads is never enough to buy new data. The cost of the data keeps increasing as you earn. It’s all a gimmick. ## Most praised reviews (10 highest-rated) ### 5/5 — asla önermiyorruö *2026-07-29, version 4.6.0* ÜSTE ÇIKSIN DİYE BEŞ YILDIZ VERDİM BOK GİBİ BİR UYGULAMA 1 SENELİK PAKET ALDIM PAKETİM ÇALIŞMIYOR PARAMI GERİ İSTİYORUÖ 🇬🇧 ### 5/5 — 非常好 *2025-12-28, version 4.5.1* 完美 ### 5/5 — GMRemix *2025-09-25, version 4.4.15* Just great. ### 5/5 — Esxcelente *2025-09-24, version 4.4.15* Para viajes internacionales funciona de manera excepcional. ### 5/5 — Does what I need it to *2025-09-23, version 4.4.15* Allows me data to send text messages when I have no other service ### 5/5 — Global Trek *2025-06-27, version 4.4.13* I’ve been using Dent for roughly two years. It has worked flawlessly in all the countries listed. Dent covers the majority of the countries most visited by tourists. I’ve noticed over the years new countries have been added. I like the fact you don’t have to think about getting a new eSIM when traveling to another country. The best part is at the end of your trip you can sell you leftover data for Dent coins which you can later use to purchase data on Dent. You can’t say that about other Esims. It’s mainly use it or lose it on other platforms. ### 5/5 — Muy buena *2025-06-08, version 4.4.13* 👍🏻 ### 5/5 — Awesome *2025-06-05, version 4.4.13* It’s really great eSIM powered on blockchain! ### 5/5 — 5 *2025-04-16, version 4.4.12* 5 ### 5/5 — Goood *2025-03-20, version 4.4.11* Very beautiful --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
