I'm currently creating an app that can automatically compare the 2 different ICCID also can send it automatically into sms. Can someone help me on how to compare these 2 ICCID, which is programmatically.

  • What problem were you having with the code you posted in [your last question](http://stackoverflow.com/questions/34890825/how-to-compare-the-iccid-of-the-simcard-that-ive-stored-to-the-new-simcard-inse#comment57520209_34890825)? – Mike M. Jan 21 '16 at 07:54
  • i'm having a difficulty in comparing these two ICCID in an automatic way, (auto compare) even if there is no trigger @MikeM. – Shane Smith Jan 21 '16 at 07:59
  • Please explain exactly what you're trying to do, because it sounds like the comparison isn't the actual problem. Do you want to do this in an Activity when the user opens your app? Do you want some sort of pop-up at boot to send the SMS if the SIM is different? Do you want to schedule a check at a certain time? What, exactly? – Mike M. Jan 21 '16 at 08:02
  • what im trying to do is to get first the ICCID of my simcard stored in my android phone, then locate it in the database. So whenever, i putted another simcard in my android phone, my app will automatically run and compare the ICCID that i've stored earlier in my database to be compared to the newly putted simcard, then make a notification that simcard is change. @MikeM. – Shane Smith Jan 21 '16 at 08:10
  • Well, apparently most, if not all, devices fire the `android.intent.action.SIM_STATE_CHANGED` broadcast when that happens. Look [here](http://stackoverflow.com/questions/10528464/how-to-monitor-sim-state-change). For those that might not, you'll have to use some other trigger; e.g., the `BOOT_COMPLETED` broadcast. [This comment](http://stackoverflow.com/questions/11009295/how-to-detect-the-sim-card-change-in-android-phone#comment14388531_11009295) has links to several questions about this topic. Please try some of those suggestions first. As it is, your question is a little too broad. – Mike M. Jan 21 '16 at 08:48
  • Thank you @MikeM. for your effort. This link may help me a lot in my thesis project. – Shane Smith Jan 21 '16 at 14:52
