Does any service provider offer an unlimited international roaming plan? I am traveling in Europe for 4 months this coming fall and have a verizon wireless blackberry bold 9930. I am looking for an unlimited plan with data/calls. I have unlocked my device so I can use any sim card but will be traveling to multiple countries so getting a local sim card won't work because once I leave that country I will be roaming. Do any companies offer unlimited roaming? Looking to use my data for emails/bbm etc.. and make calls back to the US. Any of the US providers or other people have this? Thanks for the help.
