As I understand it, the SIM card is what tells your wireless unit which service provider to use. If you have an old phone, it should be an easy matter to take the t-mobile SIM card out of it and install it in the SX-66. One note on the SX-66: the SIM card on mine had a tendency to lose contact (and my contacts would disappear) from jarring until I put a piece of scotch tape across the bottom of it. No problems after that.

LG shine, with tmobile as my carrier . dont know mms settings

MMS seettings stands for multimedia message settings.

It is used to send digital pictures tones etc from one person to another in the form of messages through these settings..

All you need to activate it is call the tmobile customer care services and place a request to get it activated ..

Activation will be free but once you send pictures or tones you will be charged..

So please do call t mobile and get the mms services activated if you need them..

How do you unlock imei 353013014179150 motorola razr v3 gsm tmobile cell phone? I bought the phone and need to use it with cingular/att.

You will need contact t-mobile to get the subsidy unlock code to use your phone internationally or on another wireless carrier. They can walk you through how to enter the code in properly. It is free of charge.

Blackberry pearl 8100 tmobile, with cingular sim

The MEP code is the same thing as a subsidy unlock code.The codes are specific to each IMEI. Meaning at&t could not unlock a T-mobile device and vice versa.You first need to find out which carrier has locked it to their network, then call them and ask for the code. I am not sure what the other carriers do, but at&t will unlock a phone bought from a third party as long as it is either a new at&t device (att in lower case) or a Cingular device and the IMEI does not appear on an active account, whether it be in write-off status or not.

Every phone ships with a factory reset option. Check out the settings for Factory Reset. This will remove all data on the mobile and will revert it back to the settings as when it was when bought.

The only carriers that allow you to setup an "Unlocked" phone, I believe are Cingular and tMobile. So it isn't really worth the effort. Plus, if the phone is ever reported as lost or stolen, it's blocked and rendered useless. (Makes it nearly pointless to buy an ebay phone for example.)
As for the applications, Blackberry are hopelessly tied to the provider. However, I noticed after the last major update; most providers seem to allow a pretty unified distribution of typical applications. The worst, least open, being in my opinion Sprint.
The blackbery themselves are pretty accessible, if you add a microSD card you can pretty much copy to it like a thumb drive.

If your set on cracking your Blackberry, I'd try Howard Forums in the RIM section...

HTC 8125

you have to contact T-mobile technical support and have them guide you through programming their internet settings on the phone. although the phone is unlocked the internet settings currently on the phone is for cingular. have them program the same settings as the t-mobile MDA phone (same phone as 8125, shipped for t-mobile)

Sx66 won't read my sim card

Try and ebay for ROM upgrades. There are many people who unlock these kinds of devices. I don't believe you can upgrade it to WM 5.0 or beyond, but that may be possible. The best bet is a newer version of PPC 2003.

The process is relatively simple. Once you have your ROM on CD or via download, You run it with your device hooked up to your PC via cable/cradle and connected via ActiveSync (3.7 or later). The warning is an improper ROM load could make your device unusable. It is a risk you have to take if you want it to make calls. Toss up: no phone Pocket PC, pocket PC phone, or shiny brick. If the XDA site has recommendations on a ROM source, they are not likely to steer you wrong. They will state emphatically, that you do not want any interruptions in the ROM upgrade process. If you have a power outage or something shuts off for any reason, you will have the shiny brick and be looking for a new device.

Unlock my blackberry 7290

Like you being with T-mobile, I bought a cingular phone off ebay that wasn't unlock. My sims didn't work either. My network just said call Cingular which is now AT&T and they gave me the MEP code to unlock it. Beware, you need to confirm all of your information from your network before they will help you.
