Here's a link regarding Bell Mail configuration:

For POP3 (incoming), you should be using port 995
For SMTP (outgoing), they suggest that you use port 587 if 25 is blocked.
POP/SMTP settings are usually pretty much standard and in most cases, well established. There are differences in assigned ports and security in use but in most cases, its pretty much generic. Whether you're using the standard Android client, Outlook, or any other mail client on any other device, they should all work barring some specific bugs or local network restrictions.
Have you checked your own router to see whether there are any port filtering/firewall settings which may be preventing the client from connecting? If you're not sure, you can check using another device (PC/Mac) on your home network. This will determine whether its your ISP/router or Arc and/or mail client that's at fault.
You could also try from a public access WiFi hotspots in your area.
