获取SIM卡subId,SlotId,获取卡1&卡2 subID，SlotId

获取两张卡的卡信息：

SubscriptionManager mSubscriptionManager = (SubscriptionManager) context.getSystemService(
        Context.TELEPHONY_SUBSCRIPTION_SERVICE);

List<SubscriptionInfo> subscriptionInfoList =
        mSubscriptionManager.getActiveSubscriptionInfoList();

if (subscriptionInfoList != null) {
    for (SubscriptionInfo info : subscriptionInfoList) {
         /。。。。/
    }
}

获取默认数据卡信息：

SubscriptionInfo subInfo = mSubscriptionManager.getDefaultDataSubscriptionInfo();

获取卡槽1&2的 subID(知道slotID)

mSubscriptionManager = SubscriptionManager.from(mContext);

SubscriptionInfo mSubInfoRecord.mSubscriptionManager.getActiveSubscriptionInfoForSimSlotIndex(mSlotId);

defaultDataSub[0] 就是你要获取的sim卡的 subid

或者

SubscriptionManager mSubscriptionManager = SubscriptionManager.from(getContext());

int defaultDataSub[] = mSubscriptionManager.getSubId(1);

知道subID，转slotID

SubscriptionManager  mSubscriptionManager = SubscriptionManager.from(getContext());

int mSlotIndex = mSubscriptionManager.getPhoneId(mSubId)
