Iphone users and international dialing issues when traveling UK and HK.
Hello. I have encounterd issues with my users while traveling Internationally. They can't dail US or other numbers while located in UK or HK so far.
Their contacts and populated with +1 and some with no +1 still had issue calling to US #.
We even had them dial the number manually without taking it from the address book and had no luck.
Any suggestions?. any known issue. btw the users was provisioned for Interntaional dial in.. and their data portion worked well.
