另一方面，这类功能提高了用户对 OEM 提供服务的依赖程度。OEM 所提供服务质量取决于同运营商的合作水平。基于 OEM 的核心业务是把产品生产出来并出售给消费者，OEM 在极大概率上无法投入巨大的资源来解决蜂窝网络的问题。OEM 有可能只同一家或几家有限运营商合作，这意味着用户最终到手的上网资源很可能是上限不高、下限不明的。具体来说，优质的一级运营商通常会与漫游目的地的多家运营商签订合作协议，允许该运营商的用户设备在目的地基于不同当地运营商的实际信号覆盖情况自动选择，而通过借用一级运营商资源的二级运营商或虚拟运营商以及全球上网方案概率上并不会拿到高优先级的网络或是所有合作运营商的入网权限。如果设备上的 SoftSIM 卡不支持最有利的网络，用户就可能会遇到信号变差甚至是无服务的情况。
We’ve made tweaks to several of our default settings in this release including defaulting to enabling automatic updates, turning off intrusive WiFi notifications, and removing the Multitasking View and System Settings launchers from the dock. System Settings is always available from Quick Settings and Multitasking View can be launched by selecting the already active workspace item in the dock. You can of course always change which apps are pinned to your dock and adjust other options in System Settings.，推荐阅读WhatsApp Web 網頁版登入获取更多信息
