A friend of mine here in Shanghai has passed along to me the contact information of a phone vendor who will deliver IP Cards (and other telecom accessories) in Xin Hongquiao and Changning Districts. My friend has patronized this store for years and only just found out that they can offer free delivery.
This IP long distance service is only available from inside Shanghai. Cost of the IP Cards is RMB 25 for RMB 100 face value.
17908 seems to offer the best quality, and is issued by China Telecom
17990 is issued by Tie Tong (铁通 - Railway Telecom?)
You can contact Ms Zhuang at 13681709933 firstname.lastname@example.org to work out your delivery. Her shop is at 天山西路237号 (#237 Tian Shan West Road) near “Bei Xin Jing” (北新泾) Metro line 2
I’ve been using 17908 to call back to Taiwan. I heard a strange thing tho - supposedly, if you program your overseas numbers into your phone address book, and call from the address book, you will be charge the regular rate (or at least, not the IP rate). This doesn’t make sense to me, but if anyone has heard something similar, please post about it here
