I got the sim card through ASAHI Net, asahi - net . jp / en / join / It requires that I add an APN but my phone is not allowing me to add a new APN let alone access the APN. This is a screen shot of what it shows me. I am not technically savvy so I appreciate any help. THANK YOU!!!
Is it a carrier handset? If it is, they probably locked down the settings.
I've been doing some searches on Google but didn't find anything helpful though.
I don't know if you already did but you can always enable Developers Mode and check if this will change anything.
Go to Settings->About->Software Information->More
Now Developers Options will be in your Settings menu, just check if it's unlocked now.
If this doesn't solve your problem, you probably want to try 1000 Google searches.
Or maybe another ROM will work.
