Dear Shu,
Thanks for contacting Top China Travel!
Regarding to the WIFI rental service, we are sorry can not offer the rental service separate from the tour at this moment due to some practical operation. But the individual rental service will come out in the further. If ypu indeed need us to offer Pocket WIFI, it is recommended to join our tour, as the deivice is not convenient for sending and receiving for individuals.
Any further request or question, please feel free to contact with us.
