Trophy data connection lost after international travel on GSM

Question

There is a discussion going on at Windows Phone Central regarding the loss of data or 3G connectivity on the Trophy after returning from international travel where the Trophy is used with a SIM card on a GSM network. http://forums.wpcentral.com/trophy/182373.htm
It seems that this is a different flavor of the issue people have had using the HTC Connection app. In any event, the only remedy is to factory reset the phone when you get back from overseas, or, using Zune, revert to a backup, which means pre-Mango, then update to Mango again.
If anyone else is having this issue please make noise to Verizon and HTC so they get on it and solve it. Yes, the Trophy works overseas, but you should not have to factory reset your phone every time you get back.

Answer 1

Ditto. Just spent 10 days inTurkey & Germany. Trophy data & voice worked flawlessly overseas on GSM. Returned to US, no 3G data. Spent 2 hrs. with tech support and six different technical types, each supposedly having “deeper access” into Verizon’s systems, all to no avail. Each tech seemed to be working off the same flow chart because we went through the same series of useless questions with no resolution to the issue.  
Ultimate solution – hard factory reset. This either needs to be a Trophy or Mango issue as wife’s iPhone 4S had no issues either abroad or upon return.
How can you advertise the Trophy as a “global” phone when you need to do a hard reset every time you come back to the States? Undocumented “feature”??? Come on Verizon, either fix it or give us phones that work!
