Ive had a microcell for about 8 months now, and with the exception of the occasional need for a restart its worked great. But yesterday my 3g light wouldnt stop flashing, so I did a reboot. Started normally and then after about 4 minutes of gps and 3g lights flashing the whole unit would stop except for the power light. Tried rebooting several times and it would get to various stages and do the same thing. Only the power light would stay on. Today, I took my old one back to the store and traded for a brand new one, set it up, activated it and as soon as it sent a activation text to my phone it did the same thing as the old one. Any ideas?
