I left a very good review before
I left a very good review before. I have used calling card for ten to twenty years from the beginning when calling card was available. What I experienced "DianhuaChina.com" is definitely the best: (1）The cost to purchase Voice Credit is one of the lowest, no maintenace fees, no connection fees; (2) no expiration. This is the best feature that I like. Because most of calling cards do have an expiration date. The quality of sound is very good， very clear also. (4) The charge is very accurate by one minute. Anyway, it is the best, I have used it since the beginning of 2018, and wish to discover this company sooner.
