Re: Supplementary services Not working

I don't know if this really works. I read a post recently on my carrier website and some are having the exact same issue and error message. Two galaxy owners said that they opened settings/connections/mobile networks and changed the connection to 3g/2g auto connect. They say it forces the connection off LTE and sets it to 4g. A temporary workaround so that they could get access to the supplementary services and turn call forwarding off until the carrier figures out a solution. It might be worth a try. The carrier technicians are putting tickets in but so far the engineers haven't found a solution.

I just switched mine over to 2g/3g and it dropped it down to 4g. I turned wifi off so I could see it. I opened supplementary services and it only took a few seconds to connect with the carrier. With wifi on a small circle rotates for 30+ seconds before it connects. The shortest time to connect might make a difference. Who knows.
