supposedly it was put out someplace by ATT but I only use their lines through Pure Talk.
Funny thing was that my Galaxy A 21 s actually could ue 4G speed, aka LTE, but the phone was not approved by ATT as were not a whle bunch of others...
So I got me a brand new Galaxy A42 which runs 5G and is similar to the other Galaxy but newer... I ams til doing updates to it but it will at least give me a phone to use today... More of a PITA than anything...
