I can recommend 3gsolutions. Three years running I have visited Shanghai on business and each time took out their MiFi service. Pricing is competitive and the service has been very good. Having the unit waiting for me at the hotel has been very convenient

I was happy with the product quality and service of 3gsolutions. Even though it felt like data was running out fast, I guess that's how smartphones handle data these days. The staff was responsive and helpful when I had questions regarding the product!

Excellent service and good quality. can highly recommend for anyone travelling to / in China!

I used 3gsolutions to rent 2 hotspots for our time in China. They were more than helpful with any questions I had. The devices were delivered our hotel, and then dropped off at the airport on the way out. Both straightforward. I would recommend them.
