I am not sure about MobileTrans but Wutsapper desktop version worked.
Earlier I had put negative comment on the product but after Wondershares followup I am glad that I was able to transfer the chat from by Android device to iOS device. It took lot of effort though. The phone to phone transfer did not work however the transfer was successfully concluded through desktop using wutsapper . vip. I had requested for refund and they had refunded the amount without any hassle which is appreciable. After I got refund I had subscribed for Wutsapper whose desktop version worked. I am glad that the Whatsapp data could be transfered. The app did what is promised but the desktop version.
