Just bought a used sidekick lx, cant sign in?

You will need to reset to manufacturer settings on the phone - that would wipe out any of the previous users information and start you with a clean slate.

Call Tmobile and have them walk you through it!

Here is a link to troubleshooting your phone specifically:

It can walk you through it there too!

Hope this helps!

I actually had the same issue, you'll have to call T-Mo so they can register the sim to the new device. Once it's reset on the system you'll be able to sign in with your old id. Make sure to call from a landline or other phone.

Simple: SIGN HIM OUT. Go to the menu button thats like 3 lines, (you know, on the top right), click sign out.

if it doesn't work, call your local t mobile and tell them to sign it out. and register YouR sim info.

easy way when you turn on the phone

press menu and R at the same time

and wait for it

then it will restart then you can make ur own tmail account
