You need the data plan to accomplish this... You cannot simply pop a sim in and use the BB that way.
Yes, with the unlimited plan you receive 100 MMS messages on the 7100 or 100 SMS on the 7520. Again, receive only on the 7520...so that discussion doesn't blow up again.
You are only allowed INCOMING messages.
