My BB Bold 9900 / 9930 says Insert Sim Card even when there is a sim card inserted

Question

I've been using this simcard with my BB Bold 9930 for  5 months now and then 2 days ago my phone opened at the blackberry protect log-in pagethat happens when you use a new simcard (which I didn't). so i entered my username and password but then it will show that the username and password doesn't match but when i opened it in my computer and checked it.. it was a match. so i tried switching off my phone and then opening it again but then it will come out again and then again doesn't recognize my password.. i've been doing this until i reached the last attempt where after which they will disable your account for 15 minutes before you can try again. so what i did was to wait and try again until i was able to open it. it was working until yesterday when i restarted my phone again and then after a while the log-in page appeared again but this time it accepted my password then an "initializing sim card" appeared on my phone for a while after which the Insert sim card sign was there. so i tried turning it off and removed and re-inserted my sim card for 6 times it keep saying insert sim card everytime i open it. so i tried using another sim card of my friend which is the same network as mine and inserted my sim card on another phone! my simcard worked on the other phone and so as my friend's sim card worked on my blackberry! i don't know why my blackberry doesn't recognize my simcard! i can't switch to a sew simcard (number) because i am on a postpaid line now and it has a contract for 2 years, so i couldn't throw it away and use a new one! 
Help anyone pls. how could i make my simcard worked on my blackberry again! Thanks!!

Answer 1

If you're having issues with your SIM card, Globe Telecom should allow you to swap it for another at no cost to you.  Explain your experiment of exchanging SIM cards with your friend and how another SIM card worked fine in your phone.  This is clearly a faulty SIM card so it needs to be exchanged, no two ways about it.
If Globe is unwilling to do a simple swap, which any other carrier worldwide would gladly do, tell them you'd like your issue escalated to RIM for resolution because you're obviously not getting anywhere with them.  Carriers would prefer not to escalate so they might give in and give you a new SIM card.  You shouldn't have to pay for it, either.
I hope that helps you.
