In this thread we all try to beat network issues until we can all say for sure that a sim network will not work for us.
On the first page there is a list of Proxy Servers and Real Proxy Servers. Mix match them until you get a good connection. There will be a right combination for your location.
Have you considered changing your sim to another network that will work for your location? I have reviewed your inquiries to other threads and mine.Your lines are all the same and the problem recurrs for your Smart LTE.
QueenCee VPN V4 works with all networks, maybe, just maybe using other Sim networks will work. Above all, patience is required.
