Wanting to add my daughter to my multi-line account but she has tmobile

How do I add my daughter's phone to my multi-line account if she currently has tmobile? Will it cost anything or change my bill due date?

She needs to first port her number to ATT and start her own plan. Once she does that, you can invite her line to join your multiline account. You’ll then begin paying for her plan too but your renewal date won’t change.

It should also be mentioned that she has to have a compatible phone that is unlocked and will work on AT&T. The 3G shutdown has affected many phones which might have worked in the past but will not now.  Have your daughter check her IMEI on crickets IMEI check for BYOD. If it passes cricket, it should work on AT&T. Just to be sure you might want to try your sim in her phone.
