So if I replace the SIM card from my new phone, I can still have my current number? Even if the phone's gig space is much bigger than my current 64 gig iPhone?
Didn't you say in an earlier post that you have a new phone number now?
"Since I ordered it online, I have a new number"......
Not sure how that works since I haven't ordered an iPhone online. It could be that some changes were made on the line that is already registered to your account?
In that case the new phone number will be assigned to the SIM card and it will be in the new iPhone already, probably an e-SIM. This suggests that maybe some adjustment was made to your account and the phone line -- and that once you activate the new phone and line that the old one, the SIM card in the iPhone 6s, will be no longer active. ??
