Thank you gina7289 for your reply.
Wow the device won't turn on? I would be pulling my hair out if I couldn't get my device powered up. Let's see if we can get this resolved immediately.
Please connect to a wall charger for an hour and then try powering it on. Have you tried resetting the iphone? Please press and hold the home and top buttons (for approx: 15 seconds) until an apple logo appears then release and retest.
Please let me know if these steps help. These steps are for an iphone. If you have a personal hot spot device please let me know and I will provide different steps.
