our CEO travels to Vietnam regularly since 2 months and his not able to use his BB 8800 there (in china it works fine).
He is able to make voice calls, but recieving/sending emails is not prossible with a german tmobile(d1) sim card. They do not have a roaming partner in vietnam, which provides data services(EDGE/GPRS).
Even other german mobile phone companys told me, that it's not possible to use the BB in vietnam and they cannot tell me how we can get it working in vietnam. They all have no experience using a BB in a non-euopean country...
The BB is not sim-locked and i thought about buying a vietnamese sim card from mobifone oder vinaphone for him. I talked to a person from a mobile phone shop in vietnam and he told me that it's not possible to use a sim card from mobifone or vinaphone. Because it depends on another BB software version and if he installs this version on our BB, it will not work with our german sim card anymore.
Now i am really confused...because i read, that some people are able to use a vietnam sim card in their blackberry and some are able to use roaming and can recieve emails.
It would be ok for me to get a sim card from another country, which is able to use roaming in vietnam. But it should be able to work with our existing BB devices.
Any ideas or tips for me, how i can solve this problem and get it working?
Or a shop/dealer which has a deep experience with international bb usage?
Thanks in advance!
