The only way to set up the cell booster is with this app and the app crashes as soon as I try to login. It immediately crashes and tries to open the app page where it gives you the buttons to uninstall the app or open it. it's stuck in this loop. I tried clearing the cache even though I literally just installed the app and it STILL won't open. ATT, do better. Have an online setup option or let us set up through the actual ATT app because this one doesn't work.

Please update to version 1.25261.21 and see if that fixes the crash for you.

Follow the instructions in the app, plug everything in and then prepare to wait an hour plus. You will receive an email when the booster is registered and then another when it is activated. I had to open a few ports on my router per the instructions on the website under troubleshooting, but it works without an issue now even right next to my router. Don't rush it, it takes a while to connect on the AT&T side.

I'd like to say that since my previous review of this app and sending several emails to customer support listed on this app page Jeff from AT&T tech support reached out to me and was able to correct the issue with logging in to the Cell-Booster app. Without having to go through FIRSTNET which is not something the general public can access. Thank you Jeff for addressing my concern and also for the many AT&T and FIRSTNET customer's that have been posting negative reviews for several years 😀
