First time using International sim card on unlocked Bold 9650
We are traveling to Argentina.
I bought an Argentinian sim card on ebay.
Verizon unlocked my BB Bold 9650 (because I happily switched to an iPhone 6 months ago and BB has been sitting in closet).
I checked Advanced options and it does say "Security disabled"
I changed to GSM/UMTS, 2G
My question is that I can't see any evidence that the phone knows this sim card is in there.
When I try to call the Argentinian phone number, my BB does not ring, and it says it is going to a voicemail.
I am so stupid about all of this and have never used a sim before but really need to have an operating phone while in Argentina.
Many many thanks for any assistance in getting this to work.
