Clutch App

I had just opened my iPhone 14 Pro and wanted to convert my physical Verizon SIM to a Verizon eSIM. After multiple calls to customer service, both my new phone and old phone were no longer able to receive calls, texts or use data. I downloaded this app in need of cell service and within 5 minutes I was setup and ready to go. Porting my existing number was easy too. The convenience of this app definitely brings in new customers.

Easy to use!

I made the decision to switch from Mint Mobile and Visible Wireless due to sever deprioritization issues. I made the decision to go with T Mobile prepaid. I stumbled across this app and couldn’t believe how easy it was to set up on my iPhone 12 Pro.

The only “issue” I had was that I didn’t see any option in the app to port my number from my previous carrier (It assigned me a new number), but I made a phone call to T Mobile prepaid and it was ported instantly! It took maybe 5 minutes, in total, on the phone (make sure you have your account number and pin from your previous carrier). Very minor inconvenience, but if that option was added to the app, it would make this app PERFECT.

Good app but small problem with buying from outside US

I like the idea of being able to buy a 30 day prepaid plan before traveling to US. A couple months ago I was able to buy the plan without any problem while being outside of the US, but now the app shows an error while trying to open it being outside of the US. I had to use a VPN connection in order to use the app and buy the plan. It was easier last time when I didn’t have to use the VPN connection. It made more sense to give the ability to buy the plan to use in US before arriving in the country. I don’t know why t-mobile changed that.
