Finally Pipo switched to a third party 3g module! ALL pipo models equipped with integrated 3g have BIG trubles with 3g (slow and weak signal, disconnections, deep sleep not working).

This device is somewhat delayed since they first announced it. And it’s still not out on the market. This is probably just a: we’re almost there.. please wait a little bit more.
The specs look alright however it’s a little bit on the fat side compared to for example talk79-8c.
