Just moved to Singapore recently and try to find the way to surf Internet from my Google Nexus One. I failed with M1 card. However, still try one last time in SingTel (Hi!card). Amazingly, It works!!!!!!!!!!!!
1. Go to Settings > Wireless & Networks > Mobile Networks > Access Point Names.
2. Hit Menu button, create new APN.
3. Enter new APN settings. See below for the details.
4. Hit Menu button, save settings.
5. Select the new APN name, then hit the home button. Your 3G connection will shortly appear in the top bar.
Here's my configuration:
Name: SingTel Internet
APN: hicard
Username: 65ideas
Password: 65ideas
I'll try to find the way to active M1 for 3G using. Still have 130$ in that Sim card.
Updated!
Success in M1 configuration:
Name: M1 Internet
APN: sunsurfmcard
Username: 65xxxxxxxx (phone number, e.g. 6591234567)
Password: 65idea
Have fun!
