Hi,

I have 2 sim card from different countries in my phone. Both are recognised, and I can access data stored on them. However, my German sim card can not be used to make calls or send messages. When I put the same sim card in another phone everything works just fine.

Could this be a software problem or maybe just some problem with the settings, maybe connected to roaming?!

I already did one update to version BV6000_Blackview_V01_20160704, but nothing has changed.

Any help and suggestions would be greatly appreciated.

Thank you very much!

Cheers

Hi,
