Hi , how to switch to 4G ? ...
tried by entering from settings then cellular then maximum speed connection it only showed 2G and 3G ...Thank you ...... My phone is Lumia 920
Does your network provider support it and are you in a location where it's available?
Have you checked with your provider to see if they need to update your sim card?
Another possibility is you may have a handset that does not have the 4G enabled yet, same as mine. Phones for countrys where 4G is not yet widely available may have 4G disabled. I have been told that an update to enable this will be issued when 4G is finally enabled for that country.
I've been experiencing the same thing in Sweden were they sold a Norwegian / Swedish variant where 4G is disabled due to issues in Norway with 4G. Nokia has promised a fast fix (even if it's possible to fix it temporary with the ##...code) but even after almost three weeks nothing has happened. False advertisement
I fully understand your point but personally I don't mind not to have 4G temporarily, since it isn't yet available in my country anyway, then to have my phone freeze regularly due to 4G issues. I have been promised 4G update when it is available, so happy with that.
