The app takes up a crazy amount of storage space for a basic interface with basic features. That is suspicious on it's own. Then I ordered a sim card for $4.99. They checked my IMEI at the outset and said it was good when the IMEI was for a network locked device. Bought a unlocked phone to get service working and after multiple bumps to end of line with customer service, I was subjected to an unnecessary and convoluted troubleshooting process that took over 30 mins and didn't work. Worst ever!
