Strange, only Digitec carries this device with the manufacturer's no. ZA8E0003CH with 4G. Other dealers don't mention it https://www.toppreise.ch/produktsuche?q=ZA8E0003CH
If 4G is important to you, I would contact Digitec customer service to find out if the info is wrong. Especially since you've already been using the device for a week in case of a possible return.
Due to different purchasing conditions and changing suppliers over a certain period of time, price changes/fluctuations may occur. We generally work with daily prices. These can change depending on the purchase price at which we receive the item. So, for example, if we receive 5 pieces at cheaper conditions, we pass on this price. But if the 5 pieces are sold and we have to pay a higher purchase price for more pieces, we also pass on this price increase. This process can be very dynamic.
Lenovo itself does not list GPS as a specification, other sites also report missing GPS function: https://www.techidence.com/lenovo-yoga-tab-11-yoga-tab-13-and-tab-p11-plus-features-reviews-and-price/

Yes, there is an adapter in the case.
Keep in mind that since the stand is on the one side only, you can turn it upside down. So if you want better angles with the camera, it's not so easy. Not very wide lense, unfortunately. When someone is close to the camera it's okay. But if the tablet is not so close, the angles are not so good. Especially at the bottom, for example when the tablet is on a table and you want to see a kid on its baby-chair.
