My girlfriend was having trouble getting the 3G connection on her Android phone to work at full speed and while on a support chat with her telco, she needed to find her WCDMA status (Samsung Galaxy Captivate i897; Android Jelly Bean 4.2.1). She asked me how to find the information, so I figured I would share.
How to find your Android WCDMA settings
In your phone dialer, enter the following string:
This will open up your phone’s testing menu.
In this menu, select “Phone info”
Your WCMDA information is near the bottom ofthe screen.
“What the hell is a WCDMA?” I hear you ask?
The technical explanation involves lots of talk about radios and frequencies, but I’ll try and keep it English.
Essentially, if you select GSM only, you’ll have access to 2G and 2.5G. This mean you’ll see GPRS or Edge on your phone’s connection.
But since it ain’t nothing but a 3G thang, we don’t want that.
WCDMA let’s you access 3G networks via either normal 3G or HSDPA. Which means you can read this blog post faster, and that’s a good thing.
As a general rule, leave your settings at WCDMA Automatic, which means that your phone will be able to switch between these frequencies whenever they are available.TIP: If your Android loses 3G connectivity and it won’t re-connect. Turn off your data connection for ten seconds, and then turn it back on. This is a variation of the Airplane Mode trick, because it turns the 3G radio itself off and then back on, forcing it to hunt for the connection.
