Sim detected no service

[AC Question]

I currently live in south Korea. I have the HTC OnePlus 2 and wanted to use it with LG U+. it will detect the sim card but i don't get any form of service. However, the odd thing is that after i restart the phone there is maybe 1 second where it detects the service provider and i get service. I have factory reset the phone and even manually put in the APN. What else can i do or is it just the phone wont work?

Are you within service area? Have you tried a different Sim card? A different phone?

The phone may not have radios on the frequencies that LG U+ uses. Take it to your carrier for assistance.
