A:AnswerTransferring from an S7 to an S10 was easy and did not require changing SIM cards. The S10, similar yet different than S10+, but the S10 came with its own Sim card. Transfer of app, contacts, pictures etc was done via cord or wireless transfer, from old to new phone. I changed out Sim cards when I first got my S10, because that's what was done in the past, the phone didn't work. I called the customer service and that's when I found out and then I needed to switch back to the SIM card that came with the phone
A:AnswerIf your contract is already up, there's no upgrade, unless you change your plan. I let my contract expire and haven't had a contract for 4 years, and just bought my S10 in July. Still no contract.
A:AnswerThey'll transfer you to a new sim. I also upgraded from a Pixel 2 and it was seamless. Just activate the phone on the new sim preinstalled in the device.
A:AnswerYes, you can go into ringtone and choose the option to not have that feature on. You could also choose a different ringtone if that specific one does not have the option to turn it off.
