Cell phone service

Do I need to buy a Panama phone while visiting there? I have Verizon in the USA

No. You can get a Sim card for your phone just about anywhere

Your phone must be unlocked to use it in Panama.  If your Verizon phone is a CDMA as are most Verizon phones, you almost certainly cannot unlock it.  Same thing with Sprint.

Thanks, all. Have no idea what "unlocked" means or "CDMA"...but will find out. Von

No.  The easiest thing to do is buy a cheap cell phone to use while here.  There are many shops that will sell you one and set it up for you for about $25.  You buy prepaid phone cards for use in Panama.  For calls to the U.S. while here you can get Magic Jack or Skype, both VOIP, to use on your Verizon phone.
