For mobile, a old API: buildTemplateMobileAll doesn't includes the merged wifi network, call the new API: buildTemplateCarrierMetered to replace the old one. But new API: buildTemplateCarrierMetered requires non-null subscriberId. Call old API: buildTemplateMobileAll when subscriberId is NULL since the matched result is always empty when subscriberId is NULL. No any different between buildTemplateCarrierMetered and buildTemplateMobileAll.
