I recently purchased driod razr maxx through ebay as unlocked device. I am using this Device in India with a vodafone sim. Now, I am facing few issues and do not know what to do : 1. Whenever I reboot phone message came "Sim Card is from unknown source" although pressing ok remove message but how to remove it... I know why it is coming.... I wanted to remove it. 2. Mobile hotspot is not working. It directly goes to check subscription with verizon and failed. 3. Sometime I feel that there is voice breakage as well. 4. Network goes in and out randomly. First, I thought to root this device. Might be that could fix issue but as there is no support available for moto device in India so I leave that thought. I have already done Factory reset using external key but no help. Any suggestion will help me to get rid of these issues.
