Since ZTE does not offer PC Suite software downloading and installing the USB driver on your computer is the only way to connect your ZTE Smartphone or Tablet with your PC or laptop computer. I also tried the Go Air Dashboard and a T Mobile Dashboard that I downloaded and it shows good signal with them all but will not connect I have tried several settings and also tried the SIM in my friends unlocked MiFi dongle as it connects to the no P problem so I do not Ted all the settings in it and tried them in all dashboards without success. It also put a lot of things in networking would that be an issue so indeed the 3 thing will only be an opportunity thing for me when Im back in corrupt. If I put a 3mobile SIM in it switches and tells me that I need to Topup and it T Mobile SIM received 2 SMS welcome me to T Mobile then I would assume that the dongle is unlocked.Since ZTE doesnt offer PC suite software downloading and installing the USB driver on your computer is the only way to connect your ZTE smartphone or tablet with your PC or Laptop computer.I have also tried the Join Air dashboard And a T Mobile Dashboard that I downloaded and it shows good signal with all of them but will not connect I have tried several settings and even tried the sim in my friends unlocked mifi dongle which it connects to no problem so I noted all the settings in that and tried them in all dashboards without success.It also put a bunch of things in Network will that be an issue as really the 3 thing will only be an occassional thing for me when Im back in Blighty.If I put a 3mobile sim in it connects and tells me that I need to topup and the T Mobile sim recieved 2 text messages welcoming me to T Mobile so I would assume that the dongle is unlocked.
