Can't delete wrong speed dials set up by my wife

Hi Nilesh, the user's manual says, quote: "Speed dial: If you already set the speed dial numbers, then you can long press number key 2 to 9 to dial set numbers out under the standby mode.Long pressing number key 1 is to dial to voice mailbox if you already set the mailbox number." So it looks like you need to add the speed dial option in your chosen contacts details, first. Then follow the quote above. Good luck!

Create speed dial entries for fax numbers that you use frequently. The number of speed dial entries you can set up depends on the HP device. For more information, see the specifications for the HP device.
To manually create a speed dial entry 1 In the HP Solution Center, click Settings, point to Fax Settings and Setup, and then click Fax Speed Dial Settings. 2 Click New Entry. 3 In the Speed Dial Settings - New Entry dialog box, type a name and fax number, and then click OK. 4 In the Speed Dial Settings dialog box, click Save. The entry is stored on the HP device.
Note If you are creating a speed dial entry for a networked HP device and you are unable to save the entry, another user on the network might have accessed the same speed dial. Wait a few minutes and try to save the entry again. To create a speed dial entry from the Address Book 1 In the HP Solution Center, click Settings, point to Fax Settings and Setup, and then click Fax Speed Dial Settings. 2 Under Address Book, click Select From. 3 In the Address Book dialog box, select one or more names, and then click OK. 4 In the Speed Dial Settings dialog box, click Save. The entry is stored on the HP device.
Note If you are creating a speed dial entry for a networked HP device and you are unable to save the entry, another user on the network might have accessed the same speed dial. Wait a few minutes and try to save the entry again.

In order to change #01 to #21 its best just to program the number into #21 slot and then clear the memory for #1.

Start by trying to store a number at a location already used Press Menu/Set, 2 (Fax), 3 (Set Quick-Dial), 2 (Speed-Dial).

Use the dial pad to select the three-digit location (001 – 200) in which you want to erase the number and press Menu/Set.
The screen displays the name or number currently stored there, then prompts you to either 1. CHANGE or 2. EXIT.
Press the Stop/Exit key when the cursor is to the left of the digits. Everything above and to the right of the cursor is deleted.
Hit he menu/set key.

This should save the speed dial number as a blank.

I have done it. I have found a way to chance the speed dial settings on my Samsung D900i.
The following instructions work for my phone but I cannot guarantee they will work for everyone else.
YOU WILL NEED A PEN AND PAPER.
Press Menu > select Phonebook > Speed dial (4) >Select
You should see names assigned to the numbers.
Decide which speed dial number you want to change e.g. 2 Mum Mobile (remember the name)
Press Back > Contact list (1) Select
Type in/go down to that name e.g. Mum Mobile (WRITE DOWN PHONE NUMBER BECAUSE YOU ARE ABOUT TO DELETE IT)
Press Options > Delete (5) > Select > choose Yes > Back > Speed dial (4)
You should now see that Mum Mobile has been replaced with a big number 2. This means that speed dial number 2 is un-assigned.
Press Back > Contact list (1) > Select
Decide who you want to be assigned to speed dial 2 (WRITE DOWN PHONE NUMBER BECAUSE YOU ARE ABOUT TO DELETE IT)
Press Options > Delete (5) > Select > Yes (HERE IS THE WEIRD THING)
Press Back > Create contact (2) > SIM (2) >Select
Type back in the name and number of person you have just deleted > Save > Back > Speed dial (4)
You should see that Speed dial 2 is now the person of your choice.
HOW COOL IS THAT!!!!!!!!!!
Press Back > Create Contact (2) > Select > SIM (2) > Select
Type in Mum Mobile and Number (THE FIRST NUMBER YOU WROTE DOWN) > Save.
That is it, repeat the instructions until you have all the speed dials of your choice.
Hope this helps the many frustrated D900i users out there.

Hi Menu => Contacts =>Speed dials. Good luck.
