I have MetroPCS and AE is correct for $5 you call DR, but ONLY to landlines.
Now you can go to SDICard.com and buy in bulk the access numbers for calling numbers to DR. So for $20 you can buy 10 access numbers and depending on the number(landline or cell) you are going to call you can receive from 27 minutes per call or 2 hours for that one call.
