UipSim is a system that allows sending sms over your personal mobile phones. You can send sms to anywhere in the world by using the sms package defined on your line or your credit on your line.
Create a subscription via the UipSim panel. All details will be sent to your e-mail address. Make sure you use an e-mail address that you can access.
Download the android APK application from the UipSim panel to your phone. It is enough to open the application and log in with the QR code or password sent to your e-mail address.
Now you can send sms by uploading credits to your UipSim panel. When you send from the panel, all your sms messages will be sent over your phone.
