Why change something that wasn’t broken? ### 1/5 — The worst client service every experienced *2026-02-19* Worst website and client service of any phone company ever experienced **Developer response:** Hello "teflon92, Thank you for contacting us and we are sorry for the unpleasant experience you had. In addition to the "Help" section of the app's Home page, you can find support, information, information material or chat with COSMOTE's "Personal Assistant". At your disposal, Maria. ### 1/5 — Where is the English language version? *2026-01-21, version 12.3.0* Back to 4 Stars as it is now working in iOS 26.2 Down to one star as the App doesn’t work in iOS 26.1 (23B85) Any sign of the English version yet please? Now updated to three stars as the developer has said an English language version is on the way. I hope so. The App is described as being in English plus one other language, but it’s only in Greek. Where is the English language version? ### 1/5 — My number doesn’t work *2026-01-12, version 12.3.0* Cosmote sucks ### 2/5 — New layout gives me a headache *2026-01-09, version 12.3.0* This new layout of the app must be made for and by young people used to gaming! It’s confusing, cluttered and difficult to do the easiest tasks … paying bills! Now the app is all about up-selling offers and overly colourful junk. CLEAN IT UP! The worst Telco app I’ve seen in years. ### 1/5 — An app to cause seizures *2026-01-06, version 12.3.0* This is, by far, the most dysfunctional phone app I have seen in my entire life. Not only do the developers constantly change and redesign it, you get bombarded with basically everything g else that is entirely unrelated to your phone connection. When I opened it today,, my account balance disappeared under basically hidden buttons and everything on screen was to buy things and get discounts on the utterly most irrelevant things on the planet. To illustrate, imagine going to look for a bicycle and you get carpet bombed with travel packages to Mars with worm-dining inside an active volcano, drowning in sea water. Exactly. Their main page makes zero sense. Their ad agency needs to be fired, as I know how these things work in Greece. They’re justifying high budgets by delivering seizure-causing, worthless apps like these to their client, Coamote. And their payment system stopped working if you’re abroad. ### 1/5 — The new update sucks *2025-12-24, version 12.3.0* The new update does not favor users who manage multiple accounts or who pay significantly more than others. Previously, I could scroll through my accounts, quickly check their status, and proceed directly to payment or adjustments. Now I am forced to swipe through repeated advertisements and irrelevant information just to accomplish the same tasks. This redesign makes basic account management more difficult and time-consuming. If I had delivered a user interface like this at my job, I would likely have been terminated. It is hard to understand who approved this change or what problem it was intended to solve. The interface feels poorly thought out and frustrating to use. Overall, this is a terrible interface!!!! ### 1/5 — Junk Junk Junk *2025-12-12* I’m in the US managing and paying for my family’s plans, and every time I have to use this app it’s a nightmare. I’m using a valid Visa/MasterCard, and sometimes even PayPal, and yet it takes 20+ minutes of trying over and over before the payment finally goes through. Why does it keep showing “something went wrong” the first 30 times I click the button, and then randomly work? I’m not asking for anything special. I’m literally trying to GIVE YOU money. This should be the simplest part of your service, but instead it’s incredibly frustrating. The new app update is terrible for someone that has multiple numbers. You push ads but nothing useful for me to manage my account. Called your customer service numerous times. Your company is a JOKE!!! **Developer response:** Hello tsoglani, thank you very much for your comment. We are sorry for the experience you had. We will examine the issue that concerned you to see how we can simplify the process and improve your experience. At your disposal, Maria. ### 1/5 — Expensive and upsettingly bad *2025-12-05, version 12.1.0* This was the most expensive mistake that I could have made in relation to a mobile phone and I am now suffering the consequences do not subscribe ### 3/5 — iPhone 11 - 15.2.1 version - problem ISP *2025-11-28* My ISP Cosmote app on the AppStore requires 15.6 or later. My latest update is 15.2.1 and I cannot get to update it although it is on automatic update. How do I get around this issue without changing my iphone. Thank you ### 1/5 — Doesn't work *2025-11-26, version 12.0.1* After the last update it doesn't work ### 1/5 — Where is the English language version? *2025-11-14, version 11.11.0* Down to one star as the App doesn’t work in iOS 26.1 (23B85) Any sign of the English version yet please? Now updated to three stars as the developer has said an English language version is on the way. I hope so. The App is described as being in English plus one other language, but it’s only in Greek. Where is the English language version? ### 1/5 — App *2025-09-07, version 11.6.1* The app has technical difficulties I must always delete and reinstall as the same on my laptop It throws me out of the site as soon as it opens ### 1/5 — Mise à jour *2025-08-26* Impossible de l’activer ### 2/5 — Site *2025-08-13, version 11.6.1* For a company your size your site is truly very poor I could not access your sight to pay my bill or to top up today that I have managed to do so I could not make a payment as I was getting the message “ something went wrong try in few minutes “ For any company this is terrible especially for you that you are.a tele communications company It’s truly a disgrace ### 3/5 — Καλή αλλά θέλει προσοχή. *2025-08-11, version 11.6.1* Είναι αρκετά καλή η εφαρμογή αλλά θέλει προσοχή για να μη χρεώνεσαι για αγορές που δεν έκανες. Αυτό συνέβη σε μένα με ένα πακέτο δεδομένων για το εξωτερικό. Το κοιτούσα απλώς και στο επόμενο λογαριασμό φαινόταν σαν αγορά. Η «εξυπηρέτηση» πελατών δεν βοήθησε καθόλου και ένας άνθρωπος ήταν ειρωνικός. ### 1/5 — Online activation doesn't work *2025-07-28, version 11.6.0* I recommend not to purchase sim card from Cosmote online, if you are a foreigner, because you will not be able ti activate your SIM card through the application, which seems to be the only way. After successful verification of you identity, the form is not picking up your first and last name, which are mandatory fields that can't be entered manually, you are not able to move to next step. After talking to support for 12 minutes, their final response was that I need to go to their shop, and closest one is 1 hour ride from my place. I proposed to send my details by email, but they told me it's not possible. I didn't find any other way to submit my dissatisfaction, as even bot chat was closing the chat as technical problem when I mentioned the issue I have. ## Most critical reviews (10 lowest-rated) ### 1/5 — To difficult to understand *2026-08-20, version 12.15.1* The whole app is difficult to understand with too many options which are not understandable ### 1/5 — Ethan *2026-07-25, version 12.15.0* Hi. Every time I want to connect to this app, it says “wrong billing address “. And I need to update the app. It is very annoying. Shame on cosmote. I have no problem with other providers. Please use professional team! ### 1/5 — Used to work but not anymore *2026-06-30, version 12.13.0* The app used to work but now as soon as I do anything it restarts with the splash screen ### 1/5 — Gangsters *2026-06-29, version 12.13.0* Cosmote are gangsters. They will try any trick in the book to swindle you out of your money, they have for the monopoly on the market in Greece, which is the only reason people use them. If the customer service don’t like dealing with you, they just hang up the call. The payment system on the app doesn’t (currently) work for international cards. If you have any other option, take it. ### 1/5 — Subscriber profile *2026-06-22, version 12.12.0* No matter what options I select it takes me back to the same place I started. Never ending loop and I can’t access anything Just ridiculous ### 1/5 — In a constant loop *2026-06-17, version 12.12.0* No matter what I attempt to do the App keeps going back to its initial flash startup screen (where the logo comes together in an animation) making the app useless until bug is fixed! ### 1/5 — Dysfunctional *2026-06-14, version 12.11.1* I tried paying my landline phone and internet after many unsuccessful attempts via emailed notification to my account. Then attempted to add the COSMOTE app on iPad only getting continuously logo “uploads?” I managed to enter my 25 digit account number to get stuck on the Pay button. Deleted app then re added app, same nonsense. I gave up. Never have I had a harder time trying to pay a bill ### 1/5 — Unable to use app!! *2026-06-09, version 12.11.0* After opening the app and loving in it continuously cycles through the colourful display banner, waits a few seconds and does it again. I got as far as add connection. Then that’s it. It just cycles over and over. Please help! ### 1/5 — Avoid Cosmote — Greedy policies and terrible tech *2026-05-28, version 12.10.0* Easily one of the most frustrating networks I’ve ever used. They charge $5 for an eSIM, but if you switch phones, you can't transfer it online for free like normal networks. You have to physically go to a store and pay the $5 all over again. As a prepaid customer, they nickel-and-dime you constantly instead of just offering a simple plan. You can only get monthly unlimited data during specific months of the year; the rest of the time, you have to constantly muck around renewing it weekly. Good luck getting help, too. Their app and website are incredibly buggy, and their live chat is a joke—agents take 5 minutes to reply to every message you send, but the system times out and disconnects you if you don't respond immediately or let the screen lock. Extremely frustrating. ### 1/5 — Don’t find the app helpful at all *2026-05-08, version 12.10.0* Your app is not friendly when we live abroad. Your chat does not work with Apple iPhone ## Most praised reviews (10 highest-rated) ### 5/5 — USA *2026-06-24, version 12.13.0* Being from America this ph app makes it easy to get ph service ### 5/5 — Hussain *2026-03-10, version 12.6.0* Excellent work ### 5/5 — Horrible wait time with customer service *2025-07-04, version 11.4.1* I spent over an hour being connecting to 4 different people and getting nothing done. I just wanted to top-up my router that I use every summer. I wanted to avoid going to a physical store and the options aren’t available on the Cosmote App. I was forced to go to a store and even then they told me I could have done it on the app or through a representative, I almost blew-up. Waisted hours of my day to get this done. NEVER AGAIN! ### 5/5 — COSMOTE Neo *2024-10-27, version 10.12.0* Very easy to add a new account in the COSMOTE application 👍🏼👌 ### 5/5 — 1256. US *2023-11-28, version 10.2.0* U6 ### 5/5 — Excellent app *2023-09-19, version 10.0.8* Very useful app without bugs but it would be great if it can be used in Apple Watch Devices ### 5/5 — In English please! *2023-09-18, version 10.0.8* It’s a very useful app but please could it also be in English? I know we are in Greece but many of your customer are English-speaking. ### 5/5 — Good App *2023-08-20, version 10.0.5* Good app for paying the bill. Need English version ### 5/5 — Cosmote *2023-08-04, version 10.0.5* Fast and efficient ### 5/5 — Feature rich but… no English UI *2023-07-27, version 10.0.5* Coming 2-3 times a year in this beautiful country, great service from Cosmote people but… no english UI for your app. I guess this is not a priority but it would help me get many other services if i could understand/interact with your apps. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
