My question is similar to this one, however what would be appropriate solution for HTC Desire S device because it does not allow you to change your phone number on SIM card like Samsung Galaxy does? Here is what it looks like on my phone (sorry for bad focus):

The bad news is that some phones (like yours) don't support setting your own phone number. The good news is that this information is not stored on your phone but on your sim card.

So if you put your sim in another device and set your number there than you can put it back to your phone and voila, your number will show.

Some devices that support setting your phone number:

  • Apple iPhone (Be aware that newer versions have microSIM slots!)
  • Samsung Galaxy series (Read here on how to do it)
  • All ICS devices (Info)
  • Some custom roms (Including CyanogenMod)
  • Some Sony Ericsson dumbphones (e.g: C902, K550i)

If you don't have access to any of the above you can ask your carrier to do it. It is possible that they can do it OTA.

  • I tried with Motorola dumbphone, had options of setting 4 personal numbers, set all 4 with same number but HTC Desire S still showed "Unknown".

  • @Boris_yo that sets numbers on the phone not on the SIM. Try it with an iPhone or Samsung galaxy. Those are the only ones where I've seen this setting without custom ROM. CyanogenMod supports this too.

  • @Boris_yo updated with some devices and an option to have your carrier do it.

  • @RichardBorcsik Tried ##786# but got "Unknown Application". Do you think there supposed to be additional # at the end?

this happens on some network sims because they do not store the number onto the sim.

You can add the number to the sim by using a device that allows you. These devices normally do:

  • Older (non smart) devices
  • Most custom roms
  • ICS Devices
  • iPhone (below ios 5)
  • Some other stock roms
