SIM Twinning / Cloning / Duplicate for "Light Phone"

I would start with facebook chat as that was the most helpful.  I had to contact T-mobile 10 times and go to three different stores (I'm not exaggerating).  They don't do this very often and will try to gaslight you into thinking your asking for something else or will just tell you it can't be done but keep trying, maybe you'll get lucky and have this resolved quicker than I did.

 

All that said, here is what they need to do:

 

1. Establish a "data with paired digits line".  They can either set up a new digits line for you or convert an existing digits line you have.
2. Once it's set up, they need to pair the new "data with paired digits line" to your main line.  Once this is done you will receive a text confirmation that your data with paired digits line has been paired with your main line.
3. You'll need a physical sim card for your data with paired digits line to put in your 2nd phone.  The data with paired digits line will have a temporary sim assigned to it once it's set up.  You can either ask the rep that's helping you to assign it to a physical sim and ship that sim to you or you can go in store and ask them to give you a sim card for the data with paired digits line.

 

You’ll likely need to pay $25 for the physical sim and you’ll definitely need to pay $10 per month for the data with paired digits line.

 

Your second phone will be able to make and receive calls and texts like your main line and have slow (but useable) data.  It actually works better than I expected with the exception of sms short codes.  Your data with paired digits line cannot receive them so you can't use it for 2fa etc.

This is the most helpful answer on here by far.

If you haven’t received a text that your number has been paired, it hasn’t been paired yet.

This can happen in real time as you are on the phone with a tech-- there is no need to wait 24 hours or 48 hours, just talk to some1 else and do battle until they pair the numbers. 

This will take a good number of phone calls and store visits, but it is possible. Persevere! It works great once you get it setup, but most t-mobile employees you speak with will have no idea what you're talking about.

Can an existing t-mobile one line be converted to a "data with paired digits line"? I just received my Light Phone 2 and would like to set up as secondary phone sharing same number for calls and messages. From previous posts seems like this is not a common request. Is there any official documentation or instructions to reference when going to request the “data with paired digits line”?

Yes you can add the data with paired digits to an existing line for $10/mo.

Thanks for all the info, everyone. tmo_Chris, and anyone who knows -- does this method using “data with paired digits” to utiizlie Lightphone as a second phone work with iphone or only Android phones?

 

I’m wondering if the whole iMessage thing is still an issue or you can avoid having to deactivate it and just use either phone throughout your day. 

 

Thanks in advance. 

Yes this works with iPhone.

Yes iMessage still needs to be disabled on your iPhone in order to receive the texts as texts-- which therefore appear on both phones.

iMessage is a proprietary apple thing, and it only works on iPhones-- no other phone can receive an iMessage.

Luckily, you can toggle off iMessage easily in settings.
