By the time I proposed this bug, the WWAN card is totally unusable, but by far Lenovo have provide a workaround: https://pcsupport.lenovo.com/jp/en/products/laptops-and- netbooks/thinkpad-x-series-laptops/thinkpad-x1-yoga-7th-gen- type-21cd-21ce/21cd/downloads/driver- list/component?name=Networking%3A%20Wireless%20WAN&id=49B19606-BEF8-41DD- BE7F-95B570C212C8 So, to me, I think it is actually okay to wait for 1.30. ** Description changed: [ Impact ] There exist no formal API to do the FCC unlock procedure[1] in the latest version of the modemmanger.
