Using IMEI checks doesn't work anymore.. There were some videos states that, even after IMEI checks were successful, the product could be fake. Scammers developed a lot nowadays..
Sir...at the second method, which is *#0*#, it has always been appearing as connection problem or MMI code invalid. Does it mean my Galaxy A55 is either furbished or not authentic? Even I checked it online in IMEI Info and there it is. So is it still enough?
