双卡项目中如何修改卡2默认为 3/4G

默认情况下卡1为3/4G,如需默认为卡2，那么需做一些修改。
如果是采用open market的自动切换规则，那么请如下修改：
SIMSwitchPolicyDefault.java
(mediatek\php?mod=tag&id=6090" target="_blank" class="relatedlink">Frameworks\base\telephony\java\com\mediatek\telephony) 文件里面的
selectCapabilitySim()函数。对相关的代码和注释都要修改，举例做如下修改：
/* scenario 3: If user not set 3G switched SIM (i.e. 3G SIM is default SIM2).
* But SIM2 not inserted , then check if there's other SIM card inserted,
* we switch 3G to other inserted SIM card automatically */
if (iccId2 == null) {
if (iccId1 ！= null) {
Log.i(LOG_TAG, "scenario 3: Need to switch capability to the inserted SIM1");
selected = ISimSwitchPolicy.CAPABILITY_GEMINI_SIM1;
} else if (iccId3 ！= null) {
Log.i(LOG_TAG, "scenario 3: Need to switch capability to the inserted SIM3");
selected = ISimSwitchPolicy.CAPABILITY_GEMINI_SIM3;
} else if (iccId4 ！= null) {
Log.i(LOG_TAG, "scenario 3: Need to switch capability to the inserted SIM4");
selected = ISimSwitchPolicy.CAPABILITY_GEMINI_SIM4;
}
} else {
Log.i(LOG_TAG, "found SIM2. stays.");
selected = ISimSwitchPolicy.CAPABILITY_GEMINI_SIM2;
}
如果不是open market的自动切换规则
那么请先参考FAQ08472 [Common]Smart 3G Switch功能和配置（TD定制），具体实现如有问题请提交eservice。

这也行吗?如果插入的是2G卡怎么办?
