SOURCE: i bought a sidekick 3 off ebay but it is still locked to the previous owner's sim card number

I had the same problem with the sidekick i bought off of ebay , when you cal customer care just tell them you got it off ebay and you need the old users information deleted, they will give you step by step instructions on how to do so. Remember to not call on your sidekick becasue you will have to restart the phone.

Bought a sharp sidekick2008 cell phone from ebay usa imported to the uk suppose to be locked to tmobile when i put my tmobile sim in it request a special code to enable the sim can u help


You can call T-Mobile and inform them that you want to use the phone in the UK on their system - with your T-Mobile SIM card and they will more than likely either unlock the phone or provide you the 'special' code to use it in the UK.

Your other alternative is to purchase an unlock code from eBay. The choice is really yours.

My phone has a restriction code when i put my telstra sim in a 3 phone it comes up with restriction code but when i put a 3 sim in there it works im ocnfused can some1 please give me the code??


The phone you have is locked to the 3 phone network provider and it will accept the Telstra SIM card until the phone is unlocked from the 3 phone network.
When you place a new or a existing SIM card from another phone provider into your mobile phone and it asks for a Security code then :-
This phone is locked to the original mobile phone provider. You need to contact this mobile provider to ask for the unlock code (security code) for this phone. You need to provide proof of ownership etc and the phone's unique IMEI number which is located inside the phone under the battery. They use this number to generate the unlock code for your phone.
They should provide you with instructions on how to enter this code into the phone.
Once you unlock the phone, then you can insert a new SIM card in this phone or sign up with another phone provider using this phone.

You could ring the phone provider and ask for the unlock security code because you are going overseas and wish to use your phone with a prepaid SIM card from another country. This maybe a free service.
The other way to get your phone unlock is to use a phone unlocking company on the Internet, they usually charge a couple of Dollars for their services. Use Google and search for "Security unlocking code” companies in your area.
You can also try this WEB site :-
http://www.mobileunlockguide.com/mobile-phone/
The IMEI number is unique the each mobile phone.
The number is printed on the label under the battery.
You can also get the IMEI number by entering this on your phone
*#06# It will then display your IMEI number and you may also get a unique global serial number. Your IMEI number should be 15 digits.

Cant get my sidekick to activate


Let me start by saying I'm not an expert, but after going through a lot of gyrations I came up with a solution that worked for me. I'm sharing it here because I haven't seen a complete concise answer anywhere.
The activation problem with Sidekick Slides is common. Most of the time, people buy a Slide without realizing that you have to purchase a "sidekick plan" from T-Mobile to get it fully activated. These phones were build especially for T-Mobile, so they're designed so that you have to have a Sidekick rate plan first to get the phone activated. By the way, this applies to a new phone as well as a phone that's been activated before, but has been 'hard reset" (where you hold the R button while re-booting.. My advice, DON'T DO THIS! Because you have to re-activate the phone.
However, there's good news for all you non-T-mobile folks who bought a Slide on eBay (or from a friend etc.) only to find it needs activation. Here's the solution. If you search eBay for "sidekick activation" you can find folks selling prepaid activation kits for around $15. They include a sim card and about $10 worth of sidekick prepaid services. Buy the kit, install the sim, and go online to register your phone (registering by phone is a pain with T-Mobile). Online you have 3 plan choices: Pay By The Day, Pay As You Go, and Sidekick. Pick Sidekick, and then provide the requested registration information. When done, your phone should be ready to go and should activate within about 5 - 10 minutes. You'll be charged $1 a day and airtime for calls, so it's not cheap, but at least the phone won't go to the activation screen when you startup.
The next question is, how to unlock the phone for other networks? IF it's not unlocked you will be prompted for special code (this is different than the user-defined password that simply locks the phone against unauthorized users). It won't work on other networks until it's truly unlocked. Again, the trusty folks at eBay can help. I searched for Sidekick Slide Unlock Codes and found numerous vendors, ranging from $6 to $12, who provide permanent unlock codes for Slides. I found on that provides the code via email (others want to mail it to you) and got my code within 30 minutes. So now I can remove the T-mobile sim and put my ATT (or other) sim in and go. I should mention that some of the Sidekick features ONLY work if you have a sidekick plan, but that's T-Mobile's and Danger's devious attempt to make us miserable. Good Luck! Hope this helps! Rick

Motorola razr v3 app.2005


It depends on which carrier the prepaid was with.
if The original prepaid and your wifes plan are both with the same carrier then it should be no problem just swap the sim over.
eg ( telstra to telstra ) or Optus To optus.
If the v3 is an Optus predaid and your wifes sim is a telsra plan then it wont accept the sim as the carriers lock the prepaid phones to their network
