This may be more related to your service provider than your phone. Please contact your provider (e.g Verizon, Sprint, AT&T, etc) for answers to this issue.

Try to push the power button and the home button at the same time! (not actually holding it, just try to do it rather quickly) If you are running IceCreamSandwich it should work (my case).

Hope it helps mate!

Everytime i try to recharge my phone or check how much cash left i have on the phone i keep receiving a message about an invalid MMI code i dont know what to do i bought my phone a month ago and it already...


Hey There! You can try contacting your service provider and ask them to provide you the MMI code since your phone keeps requesting that. If its not the SP, then you should contact your service centre where you bought the phone from. Since it's been only a month, your warranty is still valid!
Other than that, regarding the MMI code, I could try to get it for you. Please provide me info on which Country you are located in and what Service Provider. I might be able to help you much further :)
