New users of Red Mobile might have a hard time getting the settings for their 3G phones via OTA. The info is not also available on their website. However, you can set the 3G settings manually.
Just follow the following settings below and configure your phone with this AP:
APN: redinternet
Proxy: no proxy / off
Homepage: http://wap.redmobile.com
You should be able to connect to 3G internet with these settings.
P.S. The OTA settings for getting 3G configured is by sending “RED < handset model >” to 9969.
