Updating sprint phone
If someone on your Sprint Family Locator account gets a new phone but keeps the same number, you don’t have to do a thing. Once they’ve activated their new phone, you’ll be all set, nothing for you to change. If you insert a new SIM card into your i Phone or i Pad, you need to download the carrier settings for your new carrier.
If Sprint does merge with T-Mobile, the combined company will have an unusually complicated, tri-band 5G setup, and I don't know if even the late-2019 phones like the Samsung Galaxy Note 10 will be able to handle it; it may be 2020 before phones can access all of the different bands and systems the combined carrier would use.A carrier reset is almost always necessary if you’re activating a device or if you’re having trouble receiving voice, text, or a data connection.This reset sends your device’s new information to the network so that you can get service.When a carrier setting update is available, you'll be prompted to install it.If your carrier releases a mandatory update, you'll see an OK button instead of an Update button to let you know that the update was downloaded and installed.
