My son broke his phone, so I decided to get him a new one. After going to the local at&t store, I found out that his phone isn't avaible for an upgrade, but his brothers is. Can I use his brothers upgrade in order to get my son a new phone? If so, am I required to have his brothers sim card or something? Thanks in advance.
You can use his brother's upgrade. If it is on a family plan, you don't need anything but an ID to prove you are able to make the upgrade on that account. If his brother is on another account, his brother will need to be there too.
