This will be the only time I ever use this service ### 2/5 — Error encountered *2026-03-19, version 2.4* Too much error and bug ### 1/5 — Useless app *2025-12-24, version 2.4* The are a lot of ads but nothing to understand how to control my account or how to manage roaming. It redirects me to their website. Big company, zero modern technology ### 3/5 — Ripoff *2025-10-30, version 2.4* Charging $55 for activating the eSIM strikes me as unethical. I have bought 8-9 new iPhones and never had to do this before. There are MANY hidden fees in setting up my iPhone 17 pro max. This feels under-handed and unethical! ### 3/5 — extremely slow app *2025-10-03, version 2.4* this app takes FOREVER to load on every step. can the devs do something please. actually awful user experience ### 1/5 — The worst *2025-09-20* I have called customer support. I have seven different CEOs on this case my text messages show up on the front of my screen. I’m in my messaging application when sending out an email it’s 14.9 the first time it sends out then it goes to drafts and it’s 7.4 the second time it sends out it never shows up when my sent Mail. It never shows up in my drafts. I don’t know where it goes to when signing into an application with my phone number and email address a couple months later it will tell me I never registered my email address or my phone number ### 1/5 — App is very buggy *2025-09-06, version 2.4* If you switch away for any reason (like getting your credit card info) you lose all your progress. It also crashed on me about 3 times in 15 mins signing up. ### 1/5 — Doesn’t work *2025-09-02, version 2.4* App doesn’t work. Never lets me log in ### 1/5 — Useless *2025-08-30, version 2.4* I’m actually quiet surprised this app has such a high rating. It’s basically just a password gateway and then you go through to a website. It still asks me if I want to activate a number when really the default should be to manage my account. Importantly, I just want to know my data usage for the month and I find this hard to navigate. Seems to be sales focused. I actually don’t really know what value this app gives. Useless. ### 1/5 — Annoying app *2025-07-23, version 2.4* Every time I switch out of the app it resets to the beginning. So it’s impossible for example to copy paste from a password manager. ### 1/5 — Fraudulent calling cards *2025-07-18, version 2.4* This is a scam software. The customer service attitude is very poor. I bought a card and added it to my phone, but it has not been activated successfully. I took the initiative to contact the customer service, but the customer service attitude was very poor and hung up the phone directly. Chinese people should not buy this phone card. I want to report this App scam to Apple ## Most critical reviews (10 lowest-rated) ### 1/5 — Be careful with your cc number *2026-08-10, version 2.7* I think this app is harvesting user information. I have yet to have a payment go through. Everything comes back with error code 505. Completely unusable. ### 1/5 — Error *2026-06-17, version 2.7* Errors all the time. Nevertheless you take my money each time. ### 1/5 — The worst company I have ever seen *2026-04-01, version 2.4* Worst customer service ever nothing ever gets fixed tickets never get answered no correspondence locking of numbers that you port in on your own device they stop your cellular services their device they burn your cellular services. You have to purchase more. They get upset if you email the investigation that the representatives never answered back somebody always wants to get in your accountant. Some of the worst customer service I have ever seen ### 1/5 — Garbage webview app *2026-03-10, version 2.4* Every time I change focus to a different app and come back, the app starts over from the beginning. It’s maddening. Trying to use 1Password to manage my login information and every time I switch to 1Password and back, it starts over completely fresh like I’ve never opened before. It has all of the downsides of a website and all the downside of using an app. ### 1/5 — Extremely slow *2026-03-10, version 2.4* I’m using the newest iPhone and it takes 5 min to even open this app. What are you guys doing?? ### 1/5 — Zero supporing in the chat *2026-02-23, version 2.4* 1+ hour spent time in the chat - they did nothing, always disconected and representative changes ### 1/5 — Doesn’t work anymore *2026-02-08, version 2.4* I lost my number and I am out here trying to get a new one but I can’t .. keep saying contact support ### 1/5 — The worst *2026-01-25, version 2.4* Worst customer service ever nothing ever gets fixed tickets never get answered no correspondence locking of numbers that you port in on your own device ### 1/5 — T-Ghetto. New CEO is Ghetto and ABSOLUTE TRASH. Shockingly Horrendous CustomerService Since She Came *2026-01-13, version 2.4* In many, many years with the company this is my very first review ever! The new CEO is ghetto, cheap and absolute trash. Ever since she has come on customer service has had a disrespectful sharp decline into the depths of hell. You will not be on hold for less than AN HOUR anytime you call. Morning, noon, night, you are on never ending holds. Then you finally get someone and they are SO DISGUSTINGLY RUDE. NASTY DESPICABLE ATTITUDES like they’re doing you a favor for paying them and choosing to be a customer with them. They are soooo condescending and nasty and rude and actually start arguments with you and cut you off! I have never! They are soooooo unprofessional!!! It’s absolutely disgusting. I don’t say this lightly. In fact this might be my first time ever saying this about anyone but PLEASE FIRE HER. She is ghetto, cheap and trying to make this the Spirit Airlines of phone services. Not gonna work. T-Ghetto will be the new name courtesy of the recent changes. T-Ghetto. ### 1/5 — Payment taken-service not provided *2026-01-05, version 2.4* I completed all the required information, but at the final step, right after the payment was taken, the connection was lost. Afterwards, I spent approximately 1.5 hours communicating via live chat. I was transferred to three different departments and had to explain the same issue three times. I also visited a T-Mobile store in Savannah. They told me we are not familiar with this application and no solution was provided. At this point, I have paid $50 and still have no result or service. ## Most praised reviews (10 highest-rated) ### 5/5 — So amazing!!! *2026-04-02, version 2.6* Truly grateful for this app; It took me around 5 minutes to get my number after years of not having one! 🥹 — If only I knew then ### 5/5 — totally awesome *2025-12-25, version 2.4* Wow, it only took a few minutes to get everything ready, and I went through it all on the first try! 😲 ### 5/5 — So quick and painless! *2025-12-11, version 2.4* Setting my new eSIM on the new iPhone I bought took minutes.
