Does Huawei P6 Telecom Edition support mobile or Unicom card 2G Internet access?

Huawei Telecom P6 mobile phone supports GSM and CDMA2000 dual-card dual-standby mobile phones, and supports the use of telecom 3G cards and China Unicom's 2G cards. However, because it is a telecom custom machine, the network is usually locked, so we can only use the telephone and SMS functions, and we can't use Unicom or mobile cards to access the Internet. We only support using telecom cards to access the Internet.
