Bell Canada APN Info
Since it appears that no one has added Bell's APN info to the list, here it is.
Postpaid Version 1:
APN: pda.bell.ca
Proxy: web.wireless.bell.ca
Port: 80
Username: (leave blank)
Password: (leave blank)
MMSC:
http://mms.bell.ca/mms/wapenc
MMS Proxy/Port: (see internet proxy/port)
IP (APN) Type: IPv4
Anything else not mentioned in this list should be left blank unless you know what it does, and what it should be set to.
This is used by some smartphones in the Bell lineup
Postpaid Version 2:
APN: pda2.bell.ca
Identical to Postpaid Version 1, except for the APN.
This is used by the other smartphones in the Bell lineup.
Postpaid Version 3/Prepaid
APN: proxy.bell.ca
Identical to Postpaid Version 1, except for the APN.
This is used by the "dumb" phones in the Bell lineup.
Data Modem (Turbo/Data/Modem Stick)/Tether
APN: inet.bell.ca
Again, identical to Postpaid Version 1, except for the APN.
This is used by ANY data modem in the Bell lineup, whether it's actually a data modem or not. IE: Cell Phone acting as a data modem, Smartphone acting as a data modem, your data stick, etc.
Notes:
The Postpaid 1/2 are used on Bell smartphones. I believe both Windows Mobile and Android use pda.bell.ca, while Blackberry and iPhone use pda2.bell.ca, I think. It seems that Symbian uses a mix of pda.bell.ca and pda2.bell.ca. Why, I haven't a clue. It was said that pda2.bell.ca billed data correctly, but they should both be fixed...
Postpaid 3 is used for Bell dumbphones, as proxy.bell.ca is used to enable the "Unlimited Mobile Browser". If you try to get Unlimited mobile browser through any other APN, you will be charged for the data. I have tried this to confirm it.
Data Modem is used as already stated, on any device acting as a modem. This includes tethering your phone to your (insert cool fancy gadget here), using your phone as a WI-FI hotspot, and, on the regular data modem. As I don't have a data modem, I can't play around with this APN, so I have no info on how it runs.
Hope this helps someone.
