Request your unlock from your original network, if you have served your contractual term they should not have any objections to letting you have the code (there may be a small admin cost to get it though).

My black berry says no service when i try and text or make calls i have full signal and checked to make sure the iemi number isint blocked help please

Take the battery and the SIM card out of the phone for 30 seconds, then place them back and power on your phone. If you still have problems, you should call your cell phone provider for assistance. Hope this helps.

Where is the location of the reset button

First, you do not need to reset the phone to install the sim card. You open the back, remove the battery, and the sim card installs underneath. There is a small lever you shift before it will insert properly and it should go in easily without resistance if this is switched correctly.

Secondly, if you need to do a hard reset for some reason you can do it by going to options / security options / general settings / menu / wipe handheld / "blackberry"...but this will take it back to being a clean out of the box black berry.
