I have a unlocked 8700g and am currently using a Cingular minutes plan with their BIS Personal plan ($29.99). Since the phone is unlocked I was wondering if it would be possible to simutaneously use a Cingular voice plan and a TMO data plan (it's only $19.99).
If people have done this, what are your experiences? Signal aside, are there any noticible usage differences or issues that come up?
$29.99 is a deal compared to certain other carriers who don't even offer cheaper BIS plans... Not to mention the non-US carriers that don't even offer unlimited BB data plans. If the $10 is a big hit for you then you really should switch to TMO.
