Question about Samsung D780 Cellular Phone

1 Answer

My New SAMSUNG PHONE D780 DUOS

Ya! the phone is good no doubt, but I just bought mine and I do not know how to REGISTER THE SECOND SIM,
secondly, I do not know how to SET THE VIBRATION if it has.
All this was so because the manuals that came with it were all written in other language and not English.
While the CD is not explanatory enough.
Please what do I do now?

I am not able to send SMS from the mobile phone,SGH D780 aredevi@yahoo.com


There are a few things you can do to figure out what the problem is:
  1. See if you can make a call. If not, it's quite likely you've simply run out of credit, or the D780 is not compatible with your SIM.
  2. Send SMS to a different number, maybe you've got the number wrong?
  3. Use your SIM on another phone. If it works, then your phone's faulty, and you should go to a service centre and get it fixed. If you bought it from a store, you should have it covered under warranty. If the SIM doesn't work on the other phone, then your SIM's faulty, and you may need to get it replaced.

If it does not work, you can try these methods:
Method 1:

3 - Enter the Unlock Code.

OR (if the Samsung D780 shows "Insert Correct SIM Card")

Method 2:

1 - Switch ON your Samsung D780 with a NOT ACCEPTED SIM Card.
2 - Don't bother about what's being displayed on your Samsung D780.

Mobile phone samsung D780 software corruption


O.K. it sounds like to me that it could be one of three problems, let's start here, first depending on where you live, your phone could have been "cloned", contact Samsung Customer service,and talk to tech from another phone,and keep that one handy, second, see if it just needs to be rebooted, just like computers phones hang up too. and third, did you put in any kind of memory chip, or anything like that,cause it maybe the wrong type, try these and let me know if it got ya fixed, if not please let me know, and Ill help you all I can, God bless

I can't turn off my Samsung SGH - D880


Yesterday I also got the same problem on Samsung DUOS SGH-D780!
I found temporary solution how to drop this error message and run the phone normally, but after next reboot it often become again. I will ask Samsung tech. support about this, but now here is the emergency solution:

1. Turn OFF the phone (by removing the battery)
2. Move out all the SIM cards from the phone
3. Insert the battery again (BUT DON'T TURN ON THE PHONE, just insert the battery)
4. Insert a charging cable into the phone and insert the adapter in wall outlet

(then I see the loading screen for the short time and after that CHARGING icon appears)

5. After that turn ON the phone. It will start in no-sim mode.
6. Turn OFF the phone
7. Remove battery, insert SIM-cards, insert the battery.
8. Turn ON the phone

After that it gonna be work good until next reloading...
