Extremely slow ArcSde access from cellular network

We use a 2Mb network to access ArcMap 10.2.2 to ArcSDE on SqlServer with direct connect.

In the simulation we set our office network to this bound rate. The performance was reasonable, about 3-4 second to open the  onnection, same to load a layer.

Pan/zoom was slow but not too much.

We check the simulation bound rate with transferring files and it was really 2Mb.

Then we have a cellular network (with net stick). It gives us the SAME bound rate (transfer a file takes the same.

Open Studio management on the client that connects the database is a little slow but not too much.

Opening a connection to the database takes 40 seconds. Load a layer about 35-40 seconds too and pan/zoom is almost impossible.

It has the same bound rate and other clients (file transfer, studio) works the same as the simulation.

Anybody have an idea why?
