I have an ATT LG Shine right now.I really love the T Mobile Sidekick 3.If i bought a Sidekick 3 off of OKorder and put my ATT sim card in it, will the sidekick 3 get service and everything?Would ATT know i am using a T Mobile phone?Is there any problems with doing this that i should be aware about?
If the T-Mobile phone is unlocked then you would have no problems in using the phone for voice calls and text. You will not be able to use other data services such as the browser, mms or IM since T-Mobile phones are set up where the data settings cannot be altered at all. ATT will be able to tell that you are using a non-ATT branded phone but so long as it doesn't negatively affect their network they won't have a problem, just don't expect to get any device support since they don't have any information on this phone.
Won't work if it's T-Mobile branded. Buy an unlocked one with the correct GSM bands for ATT.
it really wont work yeah u can get an unlock code but all it will do is just unlock the phone and text (sometimes not even the text) the rest of the features wont work, its not worth it sorry.

If the phone is unlocked then you should just be able to put the SIM in and go. However the Sidekick must have a data plan for all the features to work. ATT shouldn't have a problem with you using a phone from another carrier, but they may or may not be able to get all the data features to work. The incompatibility of T-Mobile and ATT 3G networks are not an issue because the Sidekick is not a 3G device. Although there will be a 3G Sidekick soon.
