4g is working but there is no LTE option available in phone

[badar581]

My 4G was working fine on the Vodafone network while I was in Qatar but after my return to home country I was unable to use the 4G as there was no option available to select LTE from settings.

However, when I took it to the market to get it fixed, the shop guy did some changes and 4G started working. I checked the speed from speedtest as well which turned out to be just fine. When I went to settings to select 3G to save battery, I was surprised to see that there was no option to select 4G in settings still.

I asked him for which he said that he did some tweaks and 4G should work fine but you should not change any network settings.

I need to ask what changes did he make to get the 4G working in such case.
Please excuse if my question is foolish but I am still surprised.

Thanks for the support.

Thanks for the reply. But the code given in the thread does not work on my phone
Also my current network is not Vodafone. It is Waridtel.

Ok so I figured out a bit. He must have changed some setting from service codes.
*#0011# works on my phone and I input the key as "Q0000" without quotes.
Please guide what was the further settings
