My phone is an LG G3. I have a monthly plan and have purchased the international roaming add-on and it seems to be activated. I have been here for 2 weeks and my phone still will not connect to a cellular network. My sim card is certainly inserted properly. It also does not say "no service," it just has the symbol for when it is trying to connect above the service bars which are not lit. I really need to get my phone working and would greatly appreciate any help.
