Blackberry is very efficient, but also consider some of the attachments that don't go through. What ultimately made me ditch a Blackberry was that WAV files. My office voicemail sends me a WAV file containing the phone message. I play the WAV files on the road to keep track. I could not get them to play on a Blackberry or a Blackberry Connect device. There were certain other large attachments that I had problems with.

Then there is the problem with the term "unlimited." Etisilat (a UAE provider) offers an unlimited Blackberry roaming plan subject to "fair usage." The fine print defines "fair usage as 20 megs." Its competitor Du gives you unlimited domestic and international. Fair usage in the UAE is 1 gig; fair usage outside the UAE is 20 megs.

Orange UK's Traveler plan is more honestly branded. It gives you unlimited UK Blackberry service and 15 megs to use abroad:

People's in Hong Kong offers an unlimited Blackberry plan subject to "fair usage." Here is their definition of fair usage:

"Fair Usage Policy: For our BlackBerry local email data usage, a fair usage limit of 50MB each month applies and for BlackBerry roaming email data usage, a fair usage limit of 25MB each month applies. PEOPLES may charge the Customer for all excess usage at a rate as thereafter local email data usage or GPRS roaming charge. Or suspend or limit the PEOPLES mobile service (or any feature of it) for any period PEOPLES think is reasonably necessary and/or terminate the PEOPLES mobile service."
