Beware of this app

Do not try this app unless you want to spend hours on the phone with T-mobile. This app will charge you without successful activation. The worse part is that it will not send you anything to give T-mobile customer care so they can reverse the charge.

They will not be abke to help you. You will have to get your bank involved. If you want to use eSim with your iPhone, please do yourself a favor and move on. T-mobile techincal support and the stores do not even know what eSim is. They are not trained on it. I do not even know why they offer this as an option.

I was forced to give up. 6 stores, techincal support, sales, and managers had no idea to help. Esim was new to them. I love T-mobile still but please train your staff and fix this app. However, I do not appreciate the hours soend on the phone and having to have my bank get involved to reverse the charge which takes weeks.

Pretty easy to use and sign up for a prepaid plan!

Pretty easy to follow along with the instructions to sign up for a new prepaid line. Set up was fast and no problems having it actually set up service. Also extremely easy to transfer my main number over to the new line with a call to T-Mobile.

Good app, gets the job done if you want to avoid paying the ridiculous 25$ SIM card fee.

T-Mobile isn’t the problem.

All these reviews are just people complaining about how T-Mobile is “behind the times”
T-Mobile is the newest company out of the other three main ones. Passed sprint, passing Verizon, will pass AT&T as well. Also so what if T-Mobile doesn’t support it just yet. Use your E-Sim somewhere else then? It’s not that hard to leave the reviews for people who actually want to review the application not the service that they’ve had for 15+ year unhappy about it. Then leave? It’s not hard. I’m sick of the hate on T-Mobile. Every carrier has its good and bad.
