LB2120 LTE Problem

Same kind of problem with LB2120, as far I have not had issues with falling back to UMTS, but I cannot choose which band I want to use. In finland we have quite strong coverage, but problem is that 850MHz bands are slow and usually connect to far away. when locking to 2100MHz usually with other modems speeds increase dramatically as it forces modem to connect to nearest station and not keep itself locked to somewhere other side of town. 

In other manufacturers modems I've always seen that it can be locked anywhere you want, but nooo.. It was wrong to assume that this would be standard feature. But LB2120 seemed nice as it has now wifi which and normal person would assume that using same money to unit without wifi would give you better LTE parts inside.. nope.
