naughtyjoshi 1 Report post Posted January 3, 2010 hi, i have blackberry 8830 bought from TATA Indiacom, now i have switched on to Airtel and wanted to use my BIS on the same. However suddenly my phone started acting funny and it just keep showing GSM whenever i try to use my airtel sim but does not allow me to use neither my data service on airtel nor calls while it shows "GSM". I visited to techinical helpdesk and they showed me that in advanced option -> SIM -> when we type MEPD it shows some password attempts to unlock GSM slot completely to be network free, however in my devise its showing " ENTER NETWORK MEP CODE (0 LEFT)", Can any one please help me to get this fixed so that i can use my BB 8830 on airtel. I have seen experts helping everyone, please help me as well. Thanks, Aayush RJ Share this post Link to post Share on other sites
Mufaddal 678 Report post Posted January 3, 2010 MEPD code is simply unlock code the unlock code shud be provided by your handset provider which in this case should be tata so when u type MEPD its asking for unlock code did u try using MFI tool on ur 8830 with bb os 4.2 ?? try it , it might work Share this post Link to post Share on other sites
