Hi guys, thanks for your response. I'll try to explain... When I bought it it came with several apps already installed of course, but one of them was a phone app that I had to have a SIMcard in a slot right next to the extra memory card slot to function.
When the simcard was installed it worked like a regular mobilphone, I could take phone calls (voicecalls) and text (sms). Now after a hard reset I only can text (sms).
I followed one of the links (Lenovo TB2-X30L spec's) and downloaded the app to get the specs on my tablet. Now I hope done this correct, because it looks kinda generic.
I'll try posting the link here:
Device Specifications and if it's not correct I'll try to figure it out (tips will be appreciated)
