Question about Xiaomi Poco X7 Pro

On your site, this product is presented by 3 suppliers: Digitec and two German companies. For Digitec, the availability is "pre-order with delivery time not confirmed "whereas technik-günstiger.de indicates delivery in 1 week. Is this really the same product, compatible with telephony services in Switzerland (e.g. Sunrise.ch)? And is the guarantee the same (including at Digitec sales outlets, e.g. in Prilly)?
