By far the best solution is to use the Bluetooth connection to the phone for your data link. If I live in China I can surf, if I am on sprint I can surf, if I am on Verizon, I can surf if I am on AT&T I can still surf. I f I am on a ship in the middle of the sea. I can surf.

If I move to another area and change providers, I can get myself setup with the new plan or get a new phone and not have to buy a new tablet as well, or tablet data card.

Even if the data link speed increased, yes bluetooth may be the bottleneck. But would you rather buy a new tablet with the new high speed link just to keep up?
