sim card - Does a dual sim android phone always return same IMEI when using android.telephony.TelephonyManager.getDeviceId() -

i have seen lot of posts says android documentation not back upwards dual sim phones.

in case want identify device store imei on server. because phone might have dual sims, using code

android.telephony.telephonymanager.getdeviceid()

will homecoming same imei each time run it, or may homecoming 1st sim slots imei 1 time , 2nd sim slot's imei other time?

because app check server give him access running on device. in case above line of code returns same sim slot's imei times, dont bother phone having dual sim. because want same imei saved during apps first run on server.

so in short wanna know running code above give me same imei times or give me imei of sim slot randomly different runs?

if dont create myself clear, please allow me know.

in android l telephonymanager.java have api device each slot. public string getdeviceid(int slotid)

so each sim can imei.

android sim-card imei dual-sim
