EM7345 4G LTE questions on ThinkPad W550S

2015-04-17, 16:48 PM

I saw ThinkPad w550s can add EM7345 4G LTE MOBILE BROADBAND.

I just want to know does EM7345 support T-Mobile LTE network in US and other international network such as in Europe  and Asia?




I did check the documents about THINKPAD EM7345 4G LTE MOBILE BROADBAND but the information about LTE supported bands are too technical to be easily understood.


I heard EM7355 has better support on international network but not sure if w550s can use EM7355 .. or other brand Mobile Broadband.

I have EM7345 working in the UK on an x1 carbon, but I cannot get it to work on t-mobile USA LTE networks -- it disconnects immediately after registering.  T-mobile said the correct bands were covered by the device, but could offer no help.
