"Not Allow To Dial Error" In China IPhone 4G

I recently purchased a SciPhone 4G with a dual Sim card phone. I was very happy with this phone. I had no problems until one day I couldn’t call out. I kept getting a not allowed to dial message every time I tried to call anyone.

I could still receive calls and send and receive texts but I couldn’t call out. After quite a bit of research on the internet I came up with a solution. None of the solutions available had all the information I needed I just kept trying different combinations until it worked.

 

Here is the step by step solution I used to remove the “not allowed to dial” message and allow me to dial out again.

1. turn off the phone
2. place 2 sims on the phone
3. restart the phone
4. keep the WLAN disabled
5. enter the engineering mode * # 82043036 #
6. select the option RF Test Tool (on my phone it’s option 13)
7. Select GSM, to accept him
8. go to Power scan
9. go to Band Select and select OK DCS1800
10. another screen will appear (model F003) look at each of the options until you find one that will have your phone appear unresponsive (this locked)
11. pressing the main button (the box) will take you to the home screen
12. go to the setup menu
13. go to network settings menu SIM1
14. this is a preferred mode
15. select one of the preferred modes GSM or WILAN
16. restart the phone and you should be ready to make calls

 

You just enter the code/s into the phone number area in the dial section and the phone will recognize it and enter into the proper mode.

I still love this phone. It has built in WIFI so I can surf the internet with out having to have a data plan from my service provider. I use T-Mobile.

Here are the particulars on my SciPhone:
Mode: i68 Quad Band Phone
Specifications:

• Dual SIM
• Dual Standby
• WiFi

Here is some important information I found that actually works on my phone.

• the special key code to enter “engineering mode” * # 82043036 #
• obtained IMEI code * # 06 #
• factory model code * # # # 66 it is NOT recommended that you use it

I must admit I was the one who caused the problem. I am the kind of person who wants to know just what settings are available on any piece of technology I have. So if you are like me and have changed a setting on your SciPhone i68 4G Quad band Phone with WIFI and get the not allowed to dial message, these instructions should help you back to making calls again.
