Correct, I already had an activated Sim card through Verizon. The Sim card I have is about 3 years old and was a replacement for my unlocked blackberry key2le to work on the network. When I first booted up the Pro1x, I follow the prompts and then change the network settings to LTE/CDMA/EvDo/GSM/WCDMA which seems to work a little better than it was first originally selected. I'm able to make phone calls and also receive them quicker but still noticeably slower than my other phone which was a galaxy s10e. Texting has its ups and downs, where it takes about 30 seconds to send or instantl
