    I was on the 3G network all this time and always wanted to try out the 4G network speed as many had claimed it to be really fast. I got my new 4G sim last month but can't seem to use the 4G network on the 1020. I checked if it was a bandwidth difference in country of manufacture and country of use but it isn't. Now I cannot even see the 4G option in the drop down list when I go to Settings>Cellular+SIM >SIM settings>Highest connection speed.... Therefore I cannot use mobile data at all. Once I put a 4G sim my local telecommunication service provider says that the 3G will not work and therefore I'm now stuck with no data. I looked up the specs of the 1020 and checked so many times and I even hard reset the phone but still doesn't show me the 4G selection in the drop down list. Anyone willing to help me out?

    What country are you based in and what country product code is your phone?

    4G is enabled in Firmware depending on the country product code. eg My India Lumia 920 didn't have the 4G option in settings because it didn't support the 4G bands in India. I flashed it to the Italian Lumia 920 firmware and could see the 4G option.

    First select the 2G, and you'll see the 4G option. It works for me.

    I live in Sri Lanka, and my phone is version RM-875. I bought the phone from Singapore a year and a half ago and I used to have the 4G option but I didn't have a 4G sim. Ever since Cyan came out and I installed it I can't select 4G even when I have the 4G sim :(

    Do you think I should flash my 1020 to get the 4G bandwidth usability? Because all in my family including my mum and sister use Lumias a 920 and 925 and they too can't use 4G... But their phones show the 4G option it just doesn't work.... For me its not even showing the 4G option.... Pls help me

    What happens if you switch SIM with your family. Will they still see 4 G? And what about you phone?

    I'm not familiar with flashing ROMs on Windows Phone. Is it safe? Will it brick my phone? Because I have so many photos and don't want to loose them. Game play is alright as long as I can download the game it self again... Anyone mind helping me?

    I think, if you enable photos backup, your photos are safe in your OneDrive account, make sure you activate it, and about game, you surely will redownload em all again, but as far as I know, any save data are safe too in game nowadays, not all game though, do it at your own risk

    Yeah I prefer backing up the photos to the computer because my data connection is a capped one and I get slow uplink speeds. Any idea on which specific ROM to download?

    I already have the app. I backed up my photos, videos and other documents. I had to manually copy the high res pictures from phone to PC as the app didn't back up the High res version. It only backed up the 5mp version of my pics.

    Could you educate me on which ROM to download and from where I can download it. And also steps to flash it on my 1020? Thanks.

    No you have mistaken your phone supports 4G band.I have 4G option to choose in my Lumia 925 coz Microsoft enabled it in latest dev preview build 8.10.14203.206 (otherwise denim ).......4G option is added as the Highest connection speed in India. Dont know whether this holds for some other regions too...
    Here is a screenshot of it

    I had the 4G option before the Cyan update but I didn't have a 4G sim to make use of the LTE bands. Now I've got the 4G sim but no 4G option in the highest connection speed. I'm downloading the AU CV ROM via Nokia data packet manager. And will try flashing it once it is downloaded. If it works then ill be relieved but if it doesn't then I guess ill have to revert to a 3G sim once again. Lets see how everything goes. :)

    You may need to update the post as it may be helpful to others seeking 4G option in their Phones :)
