Ok, Having some problems getting this switch to 100%. I have a german bought HTC ONE and I moved back to the US. The phone is unlocked and has not been rooted (yet). I first had problems findiing a good APN but I think I have that part fixed. the problem now is the service. We have a Samsung Galaxy S2 also from germany and using straight talk and it works fine. it stays on the HSDPA but mine on the other hand keeps jumping off of HSDPA onto GSM/EDGE and is causing very slow/no internet. If someone could type *#*#4636#*#* on there HTC ONE and screen shot there setting that might help me find the right settings for me. Thanks.
