Lets try updating your phones software, which you can do in settings in the about phone selection.
Or you can try rebooting the device by pressing the Vol down and power buttons simultaneously until phone power up logo comes on then release. Then it should power up normally.
If these steps dont help contact your service provider about the situation.

Blackberry w9700 dual sim. it says "not allowed to dial." how fix this? :(

You should be able to reset your phone by taking the following steps:

Turn on your phone, and go to the dial screen by pressing the GREEN phone icon.

In the dialing screen type the figures *#3646633#

The phone should go into engineer mode. Scroll to RF (radio frequency) test tool, this is the 10th option and will be in the second screen.

Select the RF(radio frequency) test tool option and then select the GSM option.

When a message appears hit ok to verify.


Go to the power scan option then select the band option. Click on the right arrow till you see DCS 1800 . Press OK.

The phone should enter into scan mode, wait a few minutes until it appears to have stopped, if it hasn't stopped within a 10 minute time frame proceed to the next step.

Plug the phone into a computer via a USB connection.

You will see the following options.

  • Mass storage
  • Webcam
  • COM port
  • PictBridge

Ignore all choices (!) and press on the RED (cancel call) phone key.

The phone should power OFF at this point.

Switch the phone back on and go into the settings menu

Select network setup

Select prefered mode, select GSM preferred and press OK
This step is crucial. If the change does go through you'll see mode switching to GSM, then to OK.

If it goes through smoothly go to Settings again, and click on 'Restore Factory settings...
If it the phone doesn't accept the setting you'll see mode switching then it will display UNFINISHED.
If you see that message, please go back to the first step and do everything over again. The definition of madness is doing the same thing again and again and expecting different results. But it's worth a try.
You'll be asked for a password. The password is 1122. If that doesn't work try 1212, 0000, 8888, or 1234.


A message will appear. Click Yes.
When the phone starts up again, you'll see a Chinese message. It's asking you to click on the screen for screen calibration. Click on the touchscreen.
Once that's done you'll be shown to the main menu.
Oh No! It's In Chinese!
Fear not...
To change the language back to English, just go to SETTINGS (the gears/cogs icon).
Then choose menu item 4, then 3 and you'll be able to choose English.
Still more steps...
Go back to SETTINGS, then NETWORK SETTINGS, then click on SIM1 network setup (or SIM2 network setup depending on which slot you previously put into WLAN Only).
There you'll be shown two choices: Network Selection and Preferred mode.
Make sure that Network Selection is set to AUTOMATIC and not MANUAL. If it says MANUAL, go in and change it to AUTOMATIC.
As for Preferred mode it should say GSM Preferred. If not please start the beginning again.

M001 Phone when trying to make a call it says : NOT ALLOWED DIAL"

This is for another similar clone marked with the "vaio" name but it might be useful to someone out there. I found that by following solution one above (thanks Mrfixit) to step 6 as below and then following the second part of what I found at worked for me. I reproduce the steps below:

1. make sure to have 2 sims in phone(do not use 3g sims) 2. make sure wlan is disabled 3. enter engineer mode (type in *#3646633# 4.scroll up not down to number 10 RF test tool 5.choose gsm touch ok verify ok touch power scan band dcs 1800 press ok phone will go to test looking for DES(frequencies) wait until phone crashes or seems inactive


Connect your mobile via USB cable to a PC, DO NOT CONFIRM any connection mode at your mobile, just and ONLY connect the cable!!!

11. Press the Menu button (second from the left, the one with the seven small dots on it) until you are at the main menu with the 12 icons on the display.

12. Go to "Settings" --> "Network Setup" --> "SIM1 network setup"

13. Go to "Preferred mode" and choose "GSM preferred" or "GSM only"

14. The mobile will switch to your selection, but the message that it will stays on display. Do not press anything else, just wait for about 10 - 15 seconds.

15. Disconnect the USB cable from the phone, it will show you that it has switched to your selection.

16. Get back to main menu, switch off and restart the mobile --> DONE
