There are a variety of device types all using the 5230 marketing name. The two most commonly seen on eBay in the US are the 5230-1c Nuron (Type RM-593) and the 5230-1B (RM-594). In the user guide for the Canada 5230 Nokia explains it this way:"The wireless device described in this guide is approved for use on the (E)GSM 850, 900, 1800 and 1900 and WCDMA 850, 1700-2100 (RM-593) or (E)GSM 850, 900, 1800 and 1900 and WCDMA 850 and 1900 (RM-594)."
In addition to the two types mentioned in the Canadian user guide there are also two additional types.
The Nokia 5230 (Type:RM-588 for Latin America)
The Nokia 5230-1d (Type:RM-629 for Brazil)
- Have some or all WCDMA bands 850 MHz, 1900 MHz and 2100 MHz.
- Does not have WCDMA band 1700-2100 AWS
- The FCC Designation is LJPRM-588 or LJPRM-629.
These are correctly identified as the 5230 and sometimes, about a dozen listings at a time, mis-identified as the Nuron or unlocked Nuron.
The Nokia 5230-1c Nuron (Type: RM-593) Product Code 002P9H9
- is a quadband GSM 850/900/1800/1900 MHz device.
- It has WCDMA bands 850 MHz and 1700/2100 MHz AWS.
- The FCC designation for this model is LJPRM-593.
This will work on T-Mobile US 3G networks at 3G speed. It will also work on Wind Canada.
T-Mobile and Wind Canada employ the 1700/2100 MHz AWS band for 3G. T-Mobile uses GSM 1900 MHz for 2G connections. In order for your device to use T-Mobile 3G it has to have 1700/2100 MHz AWS band enabled.
This device without the Nuron name and without "T-Mobile" on the face is available from Wind in Canada in both white and black. It is designated the 5230-1c.
AT&T and many other carriers use the 850 MHz and/or 1900 MHz WCDMA band for 3G connections. In Oklahoma City my Nuron with the SIM restriction removed operates on the AT&T 3G network.
How to Tell The Difference?

All phones will make phone calls on any GSM network. The difference is "which is going to be best for 3G reception on your provider's network?" If you are with AT&T you'll want the 5230-1b. If you are with T-Mobile you'll want the Nuron.
Service Provider Lock on The Nuron
All New-sealed Nurons are going to have the service provider lock engaged. This will prevent you from using a non-T-Mobile SIM in the device. To use it with any GSM carrier you need to remove the SIM restriction.
- Have a paid up current account. If prepay you will need to have bought minutes in the last 30 days.
- Enter *#06# and write down the IMEI number
- Have a reason for wanting the SIM restriction removed. "I will be going to an area without T-Mobile service." for example.
- Call 611 and talk to a person
- Ask to have the SIM restriction removed.
- Give them the IMEI
- Tell them the make and model of your phone "Nokia Nuron"
- Give them a valid e-mail address so they can e-mail the instructions and unlock code.
In less than three days you will receive an e-mail that looks something like this:
T-Mobile Sim Unlock Request
