Firstly, you will need to put a SIM card into the phone that is locked, ie: a SIM card from one of the blocked phone networks. When you power up the phone, you will get the message telling you that you have inserted an invalid SIM card. Type in:
If you have done this correctly, a message will pop up telling you to hit exit, press the right soft key and choose #7 to reboot your phone. After the phone has rebooted, type in:
Then after the confirmation message has appeared, reboot the phone once again. Insert a different SIM card and power up the phone, then enter in:
That's it, if you have followed all these instructions correctly, your Samsung E715 / S307 should now be unlocked.
The 3 main pieces of information you need to enter into the calculator are as follows:
1) IMEI Number. This is a 15 digit number that can be found either under the battery of the phone, on the side of the original box you bought the phone with, or by typing in *#06#.
2) Lock Type: The lock type for your Nokia will most likely be "2". If however you have a Nokia 3650, 3660, 6600, 7650 or an N-gage, the lock type will be "5".
3) Network Provider.
Simply enter in the information relevant to your handset and network and click "Calculate". You will be presented with several unlock codes for your phone. You should remove the SIM card from your phone and enter one of the codes, if it fails, try a different one. Hopefully after entering one of the codes you should be presented with a "Phone Restriction Off" message.

Revealing Headphone and Car-Kit menus:
Please note that if you do these next tricks, the new menus can't be erased without retoring the factory default settings. To do these tricks you need to short-circuit the pins on the bottom of the phone next to where you plug in you charger.
1. To activate the "Headset" menu, you need to short-circuit pins "3" and "4". After a short time the word "Headset" will be shown in the display. Menu 3-6 is now enabled.
2. To activate the "Car" menu, you need to short-circuit pins "4" and "5". After a short time the word "Car" will be shown in the display. Menu 3-7 is now enabled.
The Rebooting Trick:
This should work on all software versions of the 6110.
1. Go to the Calendar (Menu - 8)
2. Make a note or reminder.
3. Enter some text into the edit box.
4. Hold "Clear" until the whole text is cleared, then press "Back".
5. Press "0". The main screen will now be showing but a space appears on the screen. (you can't see it)
6. Enter 4 digits (e.g. 1234).
7. Use the down arrow to move the cursor to the left side of the numbers and the space (Down arrow twice).
8. Now enter 6 digits and press the call button.
Wait for a few seconds, the screen should start to flash and reboots. It should alsowork on other menus like the "Profiles" menu.
EFR Call Quality:
To activate EFR (Enhanced Rate) Enter the code-
This improves call quality but decreases batterylife by about 5%
To deactivate it, Enter the code-
If you short-circuit theleft middle and right pins on the bottom of the phone with all connections touching each other, the Nokia software hangs! The profile "Headset" will be activated. Before you do this just activate the "Automatic Answer" in the headset profile and set the ringing volume to "Mute". Now you can use your phone for checking out what people are talking about in a room. Just place it under a table in a room and call it. The phone receives the call without ringing and you can listen to what people are saying.
There is a hidden menu inside your Nokia phone. If you want to activate it, you'll have to re-program some chips inside of your phone.
1. Check your software version. You can only continue if you have v4.33, v4.73 or v5.24.
2. Take apart the phone.
3. De-solder the EEPROM (ATMEL AT 24C64).
4. Read out the data with an EEPROM programmer and save it to a file (Backup).
5. If you have v.33 or v4.73, change the address "03B8" from "00" to "FF".
6. If you have v5.24 then change the address "0378" from "00" to "FF".
7. Write the new data to the EEPROM and solder it back to the phone,
8. Power on your phone and you should have "Netmonitor" enabled.
The Network Monitor gives you the following information.
- Carrier number
- MS RX Level in DBM
- Received signal quality
- MS TX power level
- C1 (Path loss criterion, used for cell selection and reselection). The range is -99 to 99.
- RTL (Radio link timeout).
- Indication of the transmitter status
- Information on the Network parameters.
- TMSI (Temporary Mobile Subscriber Identity).
- Cell identification (Cell ID, Number of cells being used).
- MCC (Mobile country code)
- MCN (Mobile network code)
- LAC (Location area code)
- Ciphering (On/Off)
- Hopping (On/Off)
- DTX (On/Off)
- Discard cell barred information
Check SIM Lock:
Note - If you bought your Nokia on UK Vodafone or UK Cellnet you do not need to check this because they both transmit on GSM900, and they don't lock the phones. However if you bought your phone on UK Orange or UK One2one your phone may be blocked. The reason is that they both transmitt on GSM1800. To make a call on GSM1800 you need what is known as a "Dual band" phone. A dual band phone is able to transmit on both GSM900 and GSM1800, so they lock the phones so you can't use it with any other network simcard. If you find that your phone is locked you can try different software to unlock it. (we havn't found one that works yet), or you can ask your service provider who will gladly exchange the 10 digit code for about £35.
This is how to check the status of the 4 different locks. Aslo don't try entering the wrong number, because after 3 times it will block the phone for good.
The code to read out the sim-lock status of your phone is
# = DOUBLE-CROSS
W = PRESS "*" THREE TIMES
P = PRESS "*" FOUR TIMES
+ = PRESS "*" TWO TIMES
MASTERCODE = 1234567890
Y = NUMBER 1 TO 4
The master code is a secret code. The code has 10 digits, To read out the sim-lock status you can enter every combination you want!
"Y" Shows the status of the network-lock. Here you can enter a number from "1" to "4". The "4" is for the sim-card lock.
#PW+1234567890+1# = GIVES PROVIDER-LOCK STATUS
#PW+1234567890+2# = GIVES NETWORK-LOCK STATUS
#PW+1234567890+3# = GIVES COUNTRY-LOCK STATUS
#PW+1234567890+4# = GIVES SIM-CARD-LOCK STATUS.

The famous SIM lock - Don't worry, you won't lock your phone yet. Just scroll & see the various locks that are available. Please don't lock your phone if you don't know what is the unlock code. I myself don't know, so don't ask me. This is another good check before you buy any phone, especially second hand ones. If phone is SIM locked
you may not be able to switch to other GSM operators

Menu Size option
You can extend your phone's menu to include a few more options like Customise, Edit Phone Book, etc... Note that Set Alarm does not work. Customise allows you to rearrange the sequence of the
menus & to reset your phone. DO NOT RESET your phone here!!! It will mess up your menu & you'll have to rearrange your menus again. When you want back the original menus, go back to Menu Size & reduce it.
Only GA628 with earlier software versions, will not work for GF/PF768 & all other models
1.Save a Missed Call into your phone directory
Scroll to "MissedCall", press "Yes" to display the required number. Press any number (i.e. 0 to 9),
then press "clear" once to clear that number, then press & hold "<" until you see "Store". Press "Yes"
& carry on from there...
2.Hide your number when calling (when you don't want the other party to know your number)
After dialing the required number & before pressing "Yes", press ">" twice to choose "Hide Id?" &
then press "Yes". Also works for pre-programmed & last dialled numbers, just press "No" & wait for
the number to appear on the screen first then follow same procedure.
3.Check you battery level when phone is off
Just press "No" quickly one time & wait for the battery meter to show up!
If you're sick & tired of hearing whether your redial gets through, well, don't! The phone will give a
short ring automatically when the redial gets through, so put the phone to your ear only after you hear
the ring. Note: Only works for redial, not first call!
5.Save a number into your phone memory (not SIM card)
Follow normal procedures to store a phone number. When prompted to set a storage position, press
"#" once (display will show "¤") & key in desired location, or press "#" twice for next available
position. GA628 can store 50 phone numbers in memory. Other phones may be able to store more.
6.Call a phone number from SMS message
Do you know you can do that? You can call from within a SMS message if the phone number is
written in it. Example of such a SMS message : Your wife just called. Call her at 7654321 Just scroll
the message until the phone number appears on the display, then press "Yes" to call.
Works on 6200's,8200's,1-888's,7500's,8400's and GSM StarTacs with later than version .27 software.
