Thank you for any help you're able to provide. Is there actually a technical reason for this? Note that even if your device is eligible, the speeds and performance you get on the Sprint network may not be as good as what you had on Verizon due to network band limitations. You should make sure your device is fully charged before coming to the store as the activation may take a while to complete. The set-up process will differ from customer to customer, from carrier to carrier.
As you will see later, this makes it much easier to determine what phones will work with what network.
Unlocked Phones and Your Carrier: How They Work Together
Phone frequencies and frequency bands So, on top of all the cell-phone protocols, there are also cell phone frequency bands. Cell phone network technology is always improving and getting faster. Am I allowed to switch carriers at any point if I'm not happy with them? It works mostly but due to the network differences caller ID and msg downloading will not work. Does the phone need to be unlocked to work with a Brazilian sim card? Thanks in advance for your patience.
