Member: 2289476 Status: Offline Thanks Meter: 0 | This Invalid UIM of CDMA occurs every time when the power goes off and I restart the mobile after charging. It recognizes the UIM and shows the tower. But when any number is dialed it goes dead. I deliberately switched off the mobile and rebooted the same. Then the UIM shows tower but goes Invalid when I dial some numbers. I removed the battery and sims and then inserted the same once again and restarted. Then the CDMA UIM shows the tower, but when call is made the CDMA UIM goes blank, rejects the call and UIM tower goes dead as the UIM is rejected. Surprisingly the rejected CDMA UIM works fine in other stand alone CDMA mobiles. Should I pray that my ZTE Mobile should never go off. I think the CDMA+GSM Dual SIM Mobile Technology is yet to be perfected and the buyers are fooled by manufacturers like ZTE. Last edited by nag2014; 11-09-2014 at 12:29. |

Member: 2289476 Status: Offline Thanks Meter: 0 | There is some solution in a web page in internet as given below: When display shows the "No Ruim Card " problem with inserting MTS sim of MTS handset. Solving process discuss the following Steps Step1: Dial *#0203# Step2: Display shows Factory test. Select Factory Reset from the Factory test menu and again select ok button for reset. Step3: switch off the handset and then switch on I tried this. But, I get the following message : USSD Code running; Connection problem or invalid MMI code. I am not able to progress further. I am held up. Last edited by nag2014; 11-09-2014 at 15:26. |
