    I bought my sony ericsson (W300i GSM) in mexico 3 months ago because i was living there. Now i am back in Canada since 2 weeks & I want to use my phone. I talked with the provider in mexico and they told me my phone can only work in the US (California & Nevada ). I know my phone can work with Rogers or Fido, because I already ask. Overthere the provider is Telcel with SIM card. Hope you can help me.

Because I am a longtime good customer, Cingular kindly provided me with the subsidy unlock code so that I can use my new W300i on my upcoming several-week trip to Europe, with a local SIM card that I purchase in country. They claim to have sent me both the code and the instructions for unlocking the phone by email, but I didn't get the email. After several calls back to Cingular support, I talked to a customer service rep who found and read me the instructions for entering the subsidy unlock code for this phone model. (This may be the same for other Sony Ericsson phones, I don't know.) Here they are... 1. put a non-Cingular SIM card into your W300i and power it on. 2. the display will indicate that the phone is locked, telling you that you cannot use the phone on this network. 3. disregard this 4. hit the left arrow (the left side of the navigation doughnut, I assume?) 5. hit the star 6. hit the star again 7. hit the left arrow again 8. this should result in you being at the Unlock menu. If not, start over and carefully repeat the steps. 9. the display will say "ME Lock", and in a few seconds it will change to say "Network" and show a picture of a locked padlock 10. Press Yes 11. The display will say "Unlock?" 12. Press Yes 13. The display will say "Enter NCK" 14. At this point, type in the subsidy unlock code that you received from Cingular (16 digits, probably) 15. Press Yes 16. The display will say "Network" and show a picture of an unlocked padlock (Note: if after doing this, you don't get this result, your subsidy unlock code may not be correct; do not try this more than 2 times total, as I've heard that the phone may be damaged permanently if you try a 3rd time.) 17. After doing this, the phone is permanently unlocked, and can be used on any compatible GSM network on any of the 4 bands this phone works on (which in the USA includes T-Mobile, and in Canada includes Rogers and Fido). The phone is still running software loaded by Cingular, so there may be a few menu items that may not work correctly, since they may be customized for the Cingular network service. To change the software, you have to flash new software into the phone, and I have heard that is possible, too. Someone else's post may cover that procedure. BUT MOST IMPORTANTLY YOU NEED THE SUBSUDY CODE FROM YOUR PROVIDER. I hope this helps some and GOOD LUCK!!! :-)

    For $20 I can unlock your phone. I just need the IMEI number and the make and model of your phone and who it is locked to. If you want to do this your self you need the software and the cable to connect your phone to your computer. Other than that I don't think there is any freebies out there for this particular phone. I know cause I have looked and then I finally broke down and did this. So good luck and happy hunting!!!!

SOURCE: unlock codes for sony ericsson w300i

Unfortunately, your model phone cannot be unlocked with a code like most phones. It requires special equipment, so you'll have to send it in to someone to have it unlocked.

This site:
will unlock it for $25, with 24 hour turnaround from when they receive the phone (or $30 with same day turnaround). They were featured on CNN, so they should be trustworthy. If you want to find a better deal, google search for unlock ericsson phone and you'll find quite a few sites who perform this service. I mentioned the one I did because I know it's legitimate.

The only other option would be to call Suncom and ask them to unlock it. But as you're requesting it be unlocked so you can take it to a competitor, I think it's unlikely they will oblige you.

SOURCE: i have a sony ericsson w300i phone

Ok, THIS WILL WORK! It worked on my W580i and it wasn't even supposed to. FIRST! Download (8.8MB) XS++ From HERE:! No install. It just runs.Make sure you have ALL drivers for YOUR phone. That should be under the battery. Under model... or something like that. HERE! your phone, turn it off. Start this program and click on connect.You'll have 30 seconds to plug your phone into your computer and HOLD CThe entire time! (the delete button or 2). If connected, then click at the button: GDFS. There will be a phone lock reset to "0000". Click it.It will take no more than 45 seconds. I promise. Unplug your phone, and vuala! If your phone won't turn on, try pulling out the battery,putting it back and trying again. This program is also good for flashing phones, and putting flash menus on your phone. Also unlocking it and debranding it. GOOD LUCK!

HI I ForGot Whats My Unlock Code For My Handphone (W960I) Help pls

To unlock a Sony Ericsson W960i you will first need an unlock code. You can call your phone carrier to get a free unlock code for your Sony Ericsson W960i. Your phone carrier will more in likely ask for your phone’s IMEI number. You can find your IMEI number on your Sony Ericsson W960i simply, by typing: *#06#. Once you have your free unlock code for your Sony Ericsson, we can get started with the unlocking process. Here are the steps:
Unlock Sony Ericsson W960i 1. Power up your Sony Ericsson W960i without the SIM Card in
2. Press the left arrow key/button once
3. Press the button * twice
4. Press the left arrow key/button once
5. The message “Personalize with MNC2′ will be displayed
6. Enter your free unlock code
If the above steps do not work you can try checking out this forum post on Sony Ericsson Unlocking. Otherwise, hopefully you have yourself a fully unlocked Sony Ericsson W960i phone. Best of all it was completely free. You can find the original steps from this Guide To Unlock Sony Ericsson W960i
