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.

Why do people hate this app?

Not really sure why people hate this app. It worked flawlessly for what it is designed to do. While it doesn’t make sense to have to convert a post paid like to prepaid the process was simple and my bill will actually
Go down. The dual sim functionality is excellent. The app serves no other purpose than to activate a prepaid esim and for that it was flawless
