According to your description, ZTE Tianji's mobile phone has not released cdma mobile phone, so it can't use Telecom's 3G mobile phone card. I suggest you go to Anhui Telecom Tianyi Mall to buy other brands of cdma mobile phones. There are many brands of cdma mobile phones, such as Coolpad, Apple, Huawei and so on. I hope my answer can help you.
