Here is a little Guide I've compiled of GSM Codes... Any suggestions or comments would be greatly appreciated! I did type most of this out, so if you find any mistakes, Please let me know! Also, does anyone have any idea what the Barring Codes are for the Different GSM Carriers? Guide to GSM Codes. What Are GSM Codes?-- The GSM standard allows most of the functions to be controlled by entering codes into the keypad of a mobile phone: you can set diverts and the like, accept or reject calls, or even change your PIN code by typing at the keypad. If you enter a GSM code, and it’s not valid, it simply won’t work. So don’t worry about seriously damaging your phone. Not all codes are compatible with every phone, and every carrier, but the best way to find out is to simply try! If you are having trouble setting call diversion, try ##002#(Send) and/or ##004#(Send) to clear all existing diverts first. You probably have to cancel a 'no reply' diversion before you can set another with a different timeout. Here are some commonly used Characters in GSM codes Explained: • * - Activate • ** - Register and Activate • *# - Check Status • # - Unregister • ## - Unregister and Deactivate Call Divert (These work for ALL Calls) All: • Set: **21*destination#(Send) • Cancel: ##21#(Send) • Query: *#21#(Send) No Answer: (Delay in Seconds: Max 30 seconds, 5 second Increments **nn=Number of Seconds**) • Set: **61*destination*nn#(Send) • Cancel: ##61#(Send) • Query: *#61#(Send) Unreachable • Set: **62*destination#(Send) • Cancel: #62#(Send) • Query: *#62# Cancel All • ##02#(Send) Divert Voice Calls All • Set: **21*destination*11#(Send) • Cancel: ##21*11#(Send) • Query: *#21*11#(Send) No Answer Delay in Seconds, Max 30 Seconds, in 5 Second Increments. **nn=Number of Seconds** • Set: **61*destination*11*nn#(Send) • Cancel: ##61*11#(Send) • *#61*11#(Send) Unreachable • Set: **62*destination*11#(Send) • Cancel: ##67*11#(Send) • Query: *#67*11#(Send) Busy • Set: **67*destination*11#(Send) • Cancel: ##67*11#(Send) • Query: *#67*11#(Send) Divert Data Calls All • Set **21*destination*25#(Send) • Cancel: ##21*25(Send) • Query: *#21*25#(Send) No Answer Delay in Seconds, Max 30 seconds, in 5 second increments. **nn=Number of Seconds** • Set: **61*destination*25*nn#(Send) • Cancel: ##61*25#(Send) • Query : *#61*25#(Send) Unreachable • Set: **62*destination*25# (Send) • Cancel: ##62*25#(Send) • Query: *#62*25#(Send) Busy • Set: **67*destination*25#(Send) • Cancel: ##67*25#(Send) • Query: *#67*25#(Send) Divert Fax Calls All • Set: **21*destination*13#(Send) • Cancel: ##21*13#(Send) • Query: *#21*13#(Send) No Answer Delay in Seconds, Max 30 seconds, in 5 second increments. **nn=Number of Seconds** • Set: **61*destination*13*nn#(Send) • Cancel: #61*13#(Send) • Query: *#61*13#(Send) Unreachable • Set: **62*destination*13#(Send) • Cancel: #62*13#(Send) • Query: *#62*13#(Send) Busy • Set: **67*destination*13#(Send) • Cancel: ##67*13#(Send) • Query: *#67*13#(Send) Divert Line 2 Calls All • Set: **21*destination*89#(Send) • Cancel: #21*89#(Send) • Query: *#21*89#(Send) No Answer Delay in Seconds, Max 30 Seconds, in 5 second increments. **nn=Number of Seconds** • Set: **61*destination*89*nn#(Send) • Cancel: ##61*89#(Send) • Query: *#61*89#(Send) Unreachable • Set **62*destination*89#(Send) • Cancel: ##67*89#(Send) • Query: *#62*89#(Send) Busy • Set: **67*destination*89#(Send) • Cancel: ##67*89#(Send) • Query: *#67*89#(Send) Call Barring (Note: You use call barring to control what calls can be made or received by your account. The barring code is specific to the network. Ask your service provider. Note that Call Barring can't work if call diverts are active, even the autodivert set by the network.)

SIM Pin Code: This is a pin code that locks the sim card until you enter the correct code. This protects your account, even if your sim is put into another handset. The default code is set by the Service Provider. You can change it if you like, but make sure you don't forget the new code. SIM Pin2 Code: This sim card code controls access to some of the more advanced features of the phone, such as the fixed dialing list (a restricted list of numbers the phone can call: handy if you lend a phone to a teenage son or daughter!) The default code is set by the Service Provider. You can change it if you like, but make sure you don't forget the new code. Not all networks support pin 2. Network PIN/Call Barring Code: This is the code you need to change call barring settings that are stored on the network. The default code is set by the network. You can change it if you like, but make sure you don't forget the new code. PIN Unlock Code: If you miskey (or misremember) your SIM PIN code, and enter the wrong one three times in a row, the sim will lock up, and you need to enter the unlock code to release it. You should ask your Service Provider for this code when you need it. Don't try to guess it, because after a few wrong guesses, the sim will be permanently disabled. PIN2 Unlock Code: This performs the same function as the PUK, but for SIM PIN 2. You should ask your Service Provider for this code when you need it. Don't try to guess it, because after a few wrong guesses, the sim will be permanently disabled.
Even though I've seen 004 code mentioned a few times, I haven't found it in any GSM codes guide. I'm not sure Barring Codes are even supported by the US carriers, when I enable "SIM restrictions" on my Nokia phones, the Call Barring menu is hidden. I know of a Russian provider that supports call barring, but only on their monthly fee plans (rough equivalent of Cingular PYP), not on "free" plans (rough equivalent of Cingular PAYG) and since I have the latter I couldn't try it out. It's probably worth mentioning what default PIN/PIN2 codes are: Cingular PIN: 1111 Cingular PIN2: 2222 T-Mobile PIN: 1234 T-Mobile PIN2: 5678
How do you even enable call barring? I can't enable call barring without the code -- it gives an error.
I would guess that's why it doesn't work -- AFAIK it's a network service, not a phone service, just like call forwarding. So if the network doesn't know about the barring being enabled, then the barring won't work
Yes, it is a network service. Just like call transfer. I enabled call transfer, but that didn't work either. That would be a really cool feature. -Jay
Jay, I still don't understand -- if the network doesn't support it, you can't enable it... it's just like T-Mobile prepaid doesn't support changes to call forwarding -- no matter what I do with my phone, I can't change that. What am I missing?
I have an LG CG300 I just got. It's SIM unlocked. I do not have a US GSM phone, my contract is with Verizon. The GSM phone is for overseas travel. I am in the US. When I put my Explorer SIM chip (which works on my older, dying GSM phone) I cannot place any phone calls. The Explorer SIM gives me an Estonian #, so I can receive calls from Skype that have an Estonian number. I cannot receive calls from any number outside Estonia. I see that I have Call Barring on this phone but have no clue how I'm going to be able to cancel this. It's a Cingular branded phone but I am not an AT&T customer. Does anyone have a suggestion?
My problem has nothing to do with Skype. If I put a prepaid global SIM in my CG300, I cannot place calls - only receive. Call Barring seems enabled, and is a menu option. If I use T-Mobile or AT&T SIM cards, I have no such menu option, nor any send/receive issues.
