For members of the forum that have used both a UK based CMLink SIM card, and a HK based SIM card both with a roaming package for China, can you connect if there is any significant difference in internet connectivity and performance?

Considering trying a UK CMLink SIM rather than order a HK SIM for the next trip to the motherland and just looking for assurance that the service is effectively equivalent... And all traffic is tunnelled back to the home network and is effectively unfiltered.

Cheers
