I recently got my LG classic unlocked, while trying to use my new activated service on Hello mobile which is a GSM provider it seems to turn off the service and reconnect to make a call on the service. While I tried using the same Hello service in a smartphone and it works perfectly fine.
I tried setting the APN and all exactly what hellobmobike recommends but doesn't seem to help. Though ironically I have an actual TMobile sim card which I tried in the classic to see if that also will not work properly. But fortunately it does work well. So the issue lies on the Hello mobile sim card not working properly in the Lg classic even though its unlocked. (It was the tracfone version phone).
I saw this thread but it was discussing the CDMA network.
