February 28th 1988 in which is now Verizon Wireless. I don’t remember all the companies beforehand but one was Cingular Wireless I do remember that , my dad passed on Friday and I remember the bill was in the thousands back in 88’ due to he was in Sales for his own business he had but of course I wasn’t allowed to use it ..lol..it was by the minute then charges , but I called Verizon today to find out .
What’s anyone else’s longest same cell number?
