I recently purchased a refurbished iPad Pro 10.5″ with cellular (I originally ordered the WiFi-only but received the WiFi+Cellular since they no longer had the other model. Bonus!!). Everything works fine but I noticed a rather annoying problem with Messages. For context, I live in the United States.
After I transferred my apps and data, I proceeded to check my setup and settings. In Messages, all the phone numbers listed had a +82 prefix. Google shows this as a country code for South Korea. My Contacts cards all show up properly. Messages on my iPhone show up properly. When I when back to Messages on the iPad, some of the numbers now show up properly. I checked Settings > General > Language & Region and made sure that the Region is set to “United States”.
It seems that contacts that I have messaged on my iPhone will have the proper number displayed. Messages that I receive still show the country code. If I send a message on the iPad, the recipient sees the +82 prefix in front of my number. I don’t care about getting a SIM card to enable the cellular features.
I mostly text via my phone or MacBook Pro, so this is an annoyance rather than a hindrance. How can I get my iPad to not show the country code on incoming/outgoing messages?
