Dell Wireless 5570e Slow Speed Tello Mobile

Hi im getting basically no speed on my Dell Lattitude 3350 with Sierra Wireless Dell Wireless 5570e HSPA+ card. Im on Tello Mobile. This is literally my first time using one of these things. My speed under windows network adaters is 236kbps.

What is the firmware version of this module?
Do you have the modem port to check ati3 and at!gstatus? For the signal strength
Have you tried with other sim card?
