Galaxy S5 (G900T) can't make calls on LTE

[Mike_77712]

I've recently flashed Lineage OS onto my Galaxy S5 G900T and everything worked perfect except the dialer and a few data issues i sorted my data issue reconnecting to my APN and restarting. In Lineage OS i couldn't make any calls without it immediately ending and displaying a minus sign near the LTE on the top right of the screen. After giving up i decided to flash Resurrection Remix with full gapps 7.1. It all went smoothly and then i found out the call problem had continued. I went to my preferred network type and noticed it was set to just "LTE" so i switched it to GSM/WCDMA/LTE. Then after a reboot i was able to make calls, the signal goes to 3G then i think to an H+ (I'll have to check it again) Could someone show me how to fix the issue?

Thanks in advance
