PTCI has been asked if they are blocking cellular calls to and from a nationwide carrier AT&T.
Fact: No. PTCI cannot block calls from or to AT&T cellular customers.
Fact: AT&T GSM technology does not work PTCI’s CDMA technology. GSM technology requires a sim card inserted in the cellular phone. CDMA does not use sim cards. The technology differences means neither company can reciprocate to process cellular calls nor enter into roaming agreements to process cellular calls.
For more information regarding this matter contact PTCI PR department by calling 580.338.2556 or outside of Guymon, 800.562.2556.
Can you explain what your acronyms stand for? What is CDMA and GSM? Those beyond the industry don't know those terms as loosely as you do. Thanks.
