Blackberry passport simcard not detected
I bought my BB passport in Singapore and cut my Vietnamese standard simcard into nano one to fit in. It did not detected at first but few days later when I tried in and out it did detected.
When I removed to changed into a World simcard (also cut from micro simcard) it worked well but when I changed back to my Vietnamese simcard it did not detected.
Now I come to Cuba, I cut my Cubacell simcard into nano one but it did not detected. And at this moment, whatever simcard I tried, my BB passport always says that Simcard not detected.
All these simcards work well on other phones.
I tried security swipe, clean carefully the simcards but it doesnt work.
Can anyone please help what I need to do, I dont want to send it back to Singapore for replacement given it is quite difficult to sent it from here in Cuba. Many thanks.
