Checklist

Pre-flight checklist

  1. Is your mobile phone locked to only one mobile phone operator?
  2. If locked contact your operator for unlock instructions.  If it works it should only take a few hours to fix.  If there is a legacy system problem normally with older phones it can take weeks to fix.
  3. What SIM card size does your mobile phone support?

Make your prepaid SIM card work checklist

  1. If it’s a good prepaid SIM card product then all you have to do is replace your SIM card in the phone.  Then everything should work right away even the Internet.
  2. But if you got a confusing SIM card product then there are a bunch of instructions you need to go through.  Contact the operator about those instructions if you can’t make it work.
  3. Some prepaid SIM card products also need you to type in the APN configurations.  The procedures for this are different for different versions of Android.  So you will have to google it to see how to find your APN on your specific phone.  But here’s a good place to start your search:
