本文详细讲解了如何在Android双卡设备上实现短信的发送功能，包括API调用、卡选择策略和常见问题解决，为开发者提供实用的技术指导。
I use this way to manage which sim to use for sending SMS even long message .. Its working on my dual sim phone Lenovo A319 (4.4.3), no need for root. its built on reflection.

}Add permission:
<uses-permission android:name="android.permission.SEND_SMS"/>then just call that (bloody) static method like this :)
To use SIM1:
SimUtil.sendSMS(this,0,"00970XXXXXXXXX",null,"Hi Stackoverflow! its me Maher. Sent by sim1",null,null);To use SIM2:
SimUtil.sendSMS(this,1,"00970XXXXXXXXX",null,"Hi Stackoverflow! its me Maher. Sent by sim2",null,null);But wait...that won't work if message is longer than 160 characters.. so better way:
String textSMS;
//short <160
// textSMS = "Hi Stackoverflow! its me Maher.";
//long >160
textSMS = "Hi Jerusalem, hi Cairo, Hi Prague, hi Baghdad, hi Riyadh, hi Jeddah, hi Dammam, hi Aleppo, hi Casablanca, hi Damascus, hi Alexandria, hi Algiers, hi Mosul, hi Basra, hi Arabia, hi Tripoli, hi Amman, hi Kuwait, hi Beirut, hi Abu Dhabi";
int simID = 0;//0:sim_1, 1:sim_2
ArrayList<String> messageList = SmsManager.getDefault().divideMessage(textSMS);
if (messageList.size() > 1) {
SimUtil.sendMultipartTextSMS(this, simID, "00972XXXXXXXXX", null, messageList, null, null);
} else {
SimUtil.sendSMS(this, simID, "00972XXXXXXXXX", null, textSMS, null, null);
}so you can safely pass message body without worrying about length.
------------------ Extra ------------------
I have seen that Android 22 supports multi sim cards from Android 5.1 and here is how to use it .. unfortunately I don't have device with that version for testing, so please for feedback:
SmsManager.getSmsManagerForSubscriptionId(int subscriptionId).sendTextMessage(String destinationAddress, String scAddress, String text,PendingIntent sentIntent, PendingIntent deliveryIntent);How to get subscriptionId? to review all available subscriptionID that belong to sim card:
SubscriptionManager subscriptionManager = SubscriptionManager.from(getApplicationContext());
List<SubscriptionInfo> subscriptionInfoList = subscriptionManager.getActiveSubscriptionInfoList();
for (SubscriptionInfo subscriptionInfo : subscriptionInfoList) {
int subscriptionId = subscriptionInfo.getSubscriptionId();
Log.d("apipas","subscriptionId:"+subscriptionId);
}** Please note that this code is working on 5.1. if you try to run it on older version you'd get an exception that method doesn't exist.
------------UPDATE 19.8.2015----------
Information on SIMs, are located in DB: telephony.db (by default: /data/data/com.android.providers.telephony/databases/telephony.db ) in table siminfo. See screenshot on table siminfo in DB on real device.
Fortunately there is a content provider for that:
"content://telephony/siminfo/"So basically just query data from that table.Its important to mention that slot 0 represents SIM1, and 1 represents SIM2, and slot -1 from old/removed/replaced SIMs.
This applies on Lenovo A319 . I guess that may work on other devices. Here is the util method I use:
public static List<SimInfo> getSIMInfo(Context context) {
List<SimInfo> simInfoList = new ArrayList<>();
Uri URI_TELEPHONY = Uri.parse("content://telephony/siminfo/");
Cursor c = context.getContentResolver().query(URI_TELEPHONY, null, null, null, null);
if (c.moveToFirst()) {
do {
int id = c.getInt(c.getColumnIndex("_id"));
int slot = c.getInt(c.getColumnIndex("slot"));
String display_name = c.getString(c.getColumnIndex("display_name"));
String icc_id = c.getString(c.getColumnIndex("icc_id"));
SimInfo simInfo = new SimInfo(id, display_name, icc_id, slot);
Log.d("apipas_sim_info", simInfo.toString());
simInfoList.add(simInfo);
} while (c.moveToNext());
}
c.close();
return simInfoList;
}and here is the entity class SimInfo:
public class SimInfo {
private int id_;
private String display_name;
private String icc_id;
private int slot;
public SimInfo(int id_, String display_name, String icc_id, int slot) {
this.id_ = id_;
this.display_name = display_name;
this.icc_id = icc_id;
this.slot = slot;
}
public int getId_() {
return id_;
}
public String getDisplay_name() {
return display_name;
}
public String getIcc_id() {
return icc_id;
}
public int getSlot() {
return slot;
}
@Override
public String toString() {
return "SimInfo{" +
"id_=" + id_ +
", display_name='" + display_name + '\'' +
", icc_id='" + icc_id + '\'' +
", slot=" + slot +
'}';
}
}Good luck,'.
