Porting current phone numbers - some complications

I currently have three lines of service with Sprint/TMobile.  I want to switch to Xfinity Mobile and bring all three numbers with me.  That is the easy part, but I am concerned about some complications.

 

First, I want to buy two phones from Comcast because the current phones are not compatible.  My daughter's IPhone 11 is compatible, but she is a thousand miles away.  How do I keep her current Sprint service active while she waits for her new SIM card?  Once I port the three numbers, won't all three phones stop working on Sprint?  How do I work around this?  I have no problem paying to keep both services active during the transition, but I am concerned that her phone will just stop working once the transfer is made if she does not have her new SIM caard.

 

The second complication is a little harder to explain.  We have two houses and two Comcast accounts in two different names (one in my name and one in my wife's name). One house is in DC and one is in rural Maryland.  The FAQ says numbers can only be ported in the same service area.  Our current Sprint account is based in DC.  Does this mean we can only port the numbers to our DC address? If we port the numbers to DC, must the phones we order be delivered to DC?  That will be a problem because we are currently hiding out from COVID in our rural Maryland house.

 

Am I making all of this more complicated than it really is?  I have not tried calling Xfinity Mobile to ask these questions because, well, Comcast customer service.

I recommend having your new phones and new SIM card put on the account where you are currently holed up. They will all be sent there and you will be better able manage and share your data on the one account. You will need to forward the SIM and phone to your daughter after they arrive. The porting does not happen until after you receive the new SIM cards and phones. You will be asked to activate/start the porting process separately online for each phone line but the porting doesn't actually happen until each phone is subsequently turned on with their respective XM SIM. Only then do your previous carrier accounts get terminated.

My guess is that when you separately order the SIM for your daughter that when you enter the preliminary porting information for her new line you will know right away if there may be an issue. You may want to wait and order her SIM after you have successfully received and activated your new phones from XM.

OK, that definitely solves one problem.  If worse comes to worse we can order the phones, deliver the SIM to the daughter, and only then transfer all of the numbers to the new service.

 

But this blurb from the XM FAQ causes concern:

 

  • You must establish service in the same geographical area (rate center) as your old residence. Comcast cannot port phone numbers across rate center boundaries.

 

What exactly is a "rate center"?  Are rural Maryland and Washington DC the same thing?  If they are not, then I cannot port the numbers.  And does pose a separate problem for my daughter in Florida?  Her current phone has a MD AC, if that matters.  The other two phones have AC 202 for DC.
