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.

Tmobile sidekick 3

The easiest way, though a bit pricey, would be to use T-mobiles own service:

Other options would be to try third party unlockers, though they may be a bit on the shady side. Software unlocking is possible, though it is also possible to brick your phone using untrusted software or by using the software incorrectly.

Sidekick 3 question

Your phone needs to be unlocked to use the text option. The code it is asking for is the unlock code.

All of the main sidekick features like internet, aim and email won't be available if unlocked and used on a carrier other than t-mobile.

text and calling will once unlocked though.
