Great question! When you find phone shops under the Web & Phone Shops on the iSS platform, you will see that these can be done from anywhere and do not require you to leave in a specific state, normally. However, there may be cases that require you live in a specific area, but that should be rare. But as always, please read all of the shop details and contact the scheduler if you have any questions, before completing the shop.
I hope that helps! If you have any other questions, please let us know.
Have a great day!
