I recently purchased a Verizon Blackberry Z10. I am curious to know how the phone will run off Verizon towers (straight talk rep said all blackberry phones ending with c will run off verizon tower) when the straight talk sim card is AT&T? I am out of a contract and would like to stay out of one, however need to make sure it will run off verizon tower as it has to where I live. I also need to confirm that I will have data, mms and sms, bottom line phone works in all aspects. Any info and knowledge on this is greatly appreciated! Thank you
