Hi I am still having issues with roaming. Whenever in the US I can't receive call from people in Canada nor can I make calls. Text and data work fine but calls aren't working. I have to use an app that uses data to make calls. Which is should not have to do. I am using AT&T
unless you have a cellphone that's got volte turned on, you're not gonna have great talk-ability whilst in US using the roaming add-on. You're gonna want to try using 2G for calls and hope you're fairly close to a cell tower that has it.
