I'm running into an issue with outgoing calls. I'm on Sprint while in the USA and all of my contacts are saved as +1-XXX-XXX-XXXX, and while travelling I'll have other country codes like +852-XXXXXXXX, etc. When I make a call using the stock rom, it goes directly to Call Ended rather than dialing out. I need to keep the +1 and +852 country codes so that my whatsapp/kakaotalk works from anywhere.
Is there a fix so that outgoing calls can omit the country code or work with the country code?
