Thanks for the info, the lines won't change all the lines will be the same. I guess my question is about the phone I am currently using, once I upgrade the phone on the only line off contract to get the new phone, then move the phone to my line that is still on contract ( just being a sim swap) what do I do with the phone I currently have on my line once u move the new phone over?
My reply above was the response to your question.
1. You can keep the phone
2. You can pay the ETF and then sell the phone
3. You can give it to a sibling or a child, if applicable.
4. You can transfer responsibility of it to someone else.
Having said that, you said that you wanted to get a device on a line that was off-contract. In other words, you would have a total of 4 lines. Unless you pay the ETF in advance of getting the new device, you will have 4 separate phone numbers - 1 for each device. However, you want to take the SIM card from your current device and use it in the phone you plan to purchase. Right? Well, your options on what you can do with your current device after you swapped SIMs are listed above.
