Phone unlocking?

[Chris]

Based on the discussions raised in another topic, I thought that it would be an informative and educational exercise if we could discuss the topic of unlocking GSM phones. I'm sure that there are some of you with some knowledge in this area and would be willing to share this knowledge with those of us without it.

Need I mention that this discsussion is strictly for educational purposes only? Didn't think so. ;)

:-\ well, I wont try 2 go in details but - U need the software and the data cables for the various models of phones. U can even download some of the software with kazaa! Phone unlocking has both positives and negatives. on the positive side U can personalise ur cell, on the negative side criminal elements of our Jamaican socity will steal phones unlock them and call it theirs! I witness alot of this. -- but what I'd probably love 2 find out is how to really find some way to add infinite credit to a pre-paid sim card, hey cant go 2 prison 4 my thoughts only actions.

Nothing is wrong with phone unlocking.
Where you have more than one network on the same GSM frequency they lock their phones to encourage/force customer loyalty (no one else's sim card will work).

The only way around this is Unlocking.

Equally, if I want to stick a Digicel SIM in UK phone I am going to have to get it unlocked before I travel

True, it can be used by criminals; steal a phone, then change the SIM.
Networks can bar phones by their IMEI number, so even eith a new SIM it still wont work.

Then again, you can get software that can change the IMEI number

praedere, you're totally on the ball. Nothing is wrong with unlocking a GSM phone. It's a personal preference, it's either you pay the hefty roaming charges, or you go over to the country and buy a prepaid sim card from them and slip it in your phone.

[pradere]

The only real reason they lock handsets is because it makes commercial sense. If the customer cannot easily leave the network he will just have to stay.

In reality mobile phone operators don't give 2 hoots about stolen phones. It means the can sell more phones & more phone insurance.

The question still remains.

Apart from being free from the networks hold, what other facets are there to unlocking? Will there be any added features? Will I be able to find that open port to make free calls?

[pradere]

If you can find that tell me about it quick ;D

Unlocking as far as I know is seperate from "phreaking" phones.
Unlocking simply allows any sim to work in the GSM phone.

[Nastrodamus]

eh emm
Phreaking you say ?

Actually I am doing and EDUCATIONAL research on phreaking which requires some practical application. However the parts required for that particular "box" ( ;) that is what I am told it's called ;) ) I can't seem to find here in Montego bay. If you guys can help me, we could start a thread for that. ;D For in deed education means a lot to me.

[pradere]

For your purely theoretical, educational research, I am interested to know what parts you require.

[yeayea]

When you unlock, you don't get any additional feature. Unlocking is just basically allowing the phone to accept any other sim cards, there are several levels to unlocking a phone, if not done properly it can go wrong, such as having browser locked. Most people get their phones fully unlocked, so it can be used anywhere.

The part I need is 6.5536MHz crystal


I was also asking some people some questions on the topic and was told that phone unlocking was possible without using data cables for some phones.

He said the code was #pw+1234567890+1#
where 1234567890 was a mastercode (10 digits) which is based on that phone's IMEI number (so the code is different for each phone).

I knew of the IMEI number and how to get it (#06#), but how true is the other part?????

Some one help me out on the matter

[yeayea]

You can unlock DCT4 Nokia phones with codes, but the code is self is dependent on the phone's IMEI and maybe the provider, but IMEI for sure. So the code would be different for every phone. I unlocked my DCT4 type Nokia phone (8390) which is a 8310 in Europe with a code, a thread was open on it, a guy was giving the codes away for free. He had a program, you enter the code of the network, and the IMEI and you would get a code to unlock your phone.

So you're right on the ball Nastrodamus.

Got some more information for you.

DCT-4 phones are:
3510, 6310(i), 6510, 6610, 7210, 7650, 8310, 3590, 6340(i), 6590(I), 8390
Basically newer phones.


There are 7 possible codes, if you want to fully unlock your phone you would use number seven.

For example, you were given this list:
928372746665377
785540000327343
317166434573361
727840745570042
443457367116452
124814141210315
219275733774075


The 1st code unlocks the phone. The 7th Code unlocks EVERYTHING (including browser).
Just ignore the first 6 and pay attention to the last. Now enter the exactly the following:

#pw+xxxxxxxxxxxxxxx+7#

Put that into the phone without a SIM card in phone (The "x" indicating the 7th line of code that is provided)

To access button “+” you have to press “*” twice within less than a second. To access “p” just press “*” three times within one second. To access “w” press “*” four times within one second.


1=MCC+MNC
2=GD1
3=GD2
4=IMSI
5=MCC+MNC+GD1
6=MCC+MNC+GD1+GD2
7=All Locks (Universal - multilock)

unlocking a cellphone can be a big task and can lead to you having a bricked phone.

Dude, are you serious? And that question has a double meaning...

[nevintech]

after reading all the finelines on the end user agreement (Digicel) I havent seen any info regarding unlocking of phone as an infringement(unless maybe under contract),but stil, locking phones create jobs - otherwise its a useless mechanism, its just a matter of time b4 they get unlocked
