The World NEXT ends 


Caveat: This is based on my experience in the North American market. For folks outside of NA, I'm not sure if these observations apply.

If you've had a Blackberry, you know that the cell carriers actually (at the network level) can and do block access to  your corporate BES/BESX server if you are on a cheap, er, non-enterprise data plan. That's because that traffic uses very unique ports & has attributes that make it pretty trivial to block. Verizon  | AT&T

Traveler's implementation of ActiveSync (like Exchange's) uses port 443 for traffic.. This means that it's encrypted and indistinguishable from other SSL/TLS encrypted websites. This makes it much much harder to block, and it looks like the carriers don't bother at this point.
NOTE:
Other Traveler-supported devices like Nokia, WinMobile, etc. (i.e., "legacy" devices Image:Do you need an Enterprise Data plan to use Traveler’s Activesync?) use port 8642, and carriers may block access that that port on the cheaper plans. I do remember reading somewhere that newer versions of Traveler may well move those devices over to port 443 as well.

Bottom Line:
If you're using an iPhone or activesync-enabled device to access IBM Lotus Notes Traveler , it looks like you can go with the cheaper, non-enterprise data plans. As always, YMMV and I'd appreciate hearing about your experiences.

1) Do you need an Enterprise Data plan to use Traveler’s Activesync?

Yes you are right Traveler 8.5.2 use only Port 443 (after migrating all clients)

And for the "legacy" devices there is LMC (Lotus Mobile Connect) which can tunnel all traffic through 80/443

I'm using a very cheap data plan for my iPhone + Traveler ( simyo.de ). It's only €10,- for 1GB without speed limitation.

OK; it's e-Plus and in some regions you might have problems connecting, but it is much cheaper than t-online.

I even had a 50MB dataplan with ARCOR ( €5,- )and they did not block any port ( i.e. 8642 that I had to uses in earlier versions of traveler on my Nokia device )

Lets hope WinPhone 7 has more success than the Kin or the product will be dead before IBM have completed the code!
