I also purchased a Treo 300 but it locked into At&t Rogers in Canada. I am currently using At&t Wireless in US. I would appreciate it if you could share that information about unlocking Treo 300.
Could someone help me unlock the Treo 300 phone, I almost got the code from Sprint but at the end they said that they couldn't give me the code since I wasn't going to sign up with them. I have another place that wants to charge me $30 to unlock the phone (is this a rip off?). If you can help please emial me at kkresge1@ptd.net Thanks
My wife bought me the Treo 300 not realizing that its locked. Can some one (kniteman or anybody else) email me instructions hoe to unlock this baby. I am dying to use it.
Also, since I am in the US, would this phone work on the T-Mobile GSM network?
At last, I had Treo 300 with dual SPC number that I can input. I used ##number, I inject my Flexi number (CDMA 1900MHz carrier in Indonesia) with 10496 SID. But I can't find the place for inputting Prim Channel A&B and Sec Channel A&B. So now, it still non-active even the number is active (I've registered the ESN to Flexi). Can anyone give me any help? I use Sprint device. Contact me at satriyo28@yahoo.com. Many thanks before

Maue, I got the number. Special number for each device. I try your suggestion, but On the Network Screen I can't find Detail. I only find Modify and when I tap that, they said that "This network service has been pre-installed and can't be edited'. I can't find number 8 and 9 in your instruction. Can you help me?Please contact me at satriyo28@yahoo.com

Hello, I am looking to unlock 100's of Sprint 'Treo 300's so they can be used on Verizon network. Can someone contact me that has the knowhow and capabilities.
I am interested in unlocking a treo 300 phone that i bought off of ebay. Sprint could not unlock it because i didnt know where the phone was originally purchased and what network it was originally on. The phone logs on to sprint but they cant figure it out. can someone please help me? i am willing to pay!
Anyone in the GTA have a cable and have experience doing the unlocking on a TREO 300? There's a free 2-4 in for you...
Thanks,
Matt
Your best bet is to check around other cdma forums and ebay. There are people who have access to the Sprint system so you can give them your ESN and they will give you the factory unlock code.
The answer you are all looking for is in this other thread, to "unlock" the phone, or one should say, obtain the MSL code, you need to use the serial cable and bitpim program as described here: http://www.pdaphonehome.com/forums/s...threadid=40137
thread is called "need help unlocking treo 300"
It's easy!
your phone's ESN is no secret, it should appear in the back of the phone (hex and dec form) or, when you manage to get the MSL code and enter ##[your 6 digit MSL code here] then dial, the "activating your phone" screen will tell you your phone's ESN, in hexadecimal form... not decimal, which is what a provider will most likely want, sorry. There must be a way to convert it, it's just not so straight forward though from what I can see on my phone.
Mine was printed on a sticker on the back, but when it came in, it had another paper sticker on top.

Yes but by the time you buy a serial cable plus shipping etc. you can pay for than $10 when some of these guys will get your factory msl for $2-5 or even free.
Ok, but getting your MSL is the access key to programming you phone. Very basic (i.e. same carrier) configuration is done by dialing ## then your MSL, but true service programming is done with a PC application through the treo's serial port.
So, simply put, you need the MSL for any configuration change, you most likely need cable if you want to put the phone on another carrier.
For example, I needed to change much more settings than on the basic "Activating your phone" window to get my Sprint treo 300 to work on Bell Mobility. So it depends what you want to do. If you pay 10$ for getting your MSL, only to realize there's much more settings to change, than you are getting ripped, since when you get a serial cable, you can get your MSL all too easily (see the other thread I mentionned 3 posts up). Good Luck!

To find the hexadecimal ESN on a Treo 300, first turn on the "radio" (activate the phone by holding down the button next to the antenna), then press the function-shortcut key (the big one to the right of the "..." key), then tap "Options," then tap "Phone Info." The Phone number, hex ESN, PRL rev, Firmware rev, and "PRI Checksum" will be displayed.
To convert between an 11-digit decimal ESN and an 8-digit hexadecimal ESN code, you must convert it in two parts. Convert the low-order (right-most) 6 hex digits into the low-order 8 decimal digits, and convert the high-order (left-most) 2 hex digits into the high-order 3 decimal digits.
So, for example, if your hex ESN is 60002000 you would convert it to decimal like this:
1) split it into two parts:
60, 002000
2) convert each part (and add leading zeros as necessary to get the right number of digits):
0x60 = 096
0x002000 = 00008192
3) recombine the two parts to get the decimal ESN:
09600008192
. can someone please help me? i am willing to pay!
(see the other thread I mentionned 3 posts up). Good Luck!
