Combining individuals plans to Family’s plan
I recently upgraded my phone to an iPhone 14 and my mother has a iPhone 13. We both are under the same account but we have separate plans. Both of our plans are the same (AT&T unlimited Starter plan). I Plan to add my fiancé to our account and wanted to know if it is possible to combine all 3 lines into a family plan and still keep all benefits like unlimited 5G data with no restrictions, unlimited hotspot, and unlimited texts calls and to North and South America. Also wanted to know if this will increase my monthly cost or if it will lower it by having everything as a family plan. Currently my monthly cost is about $200
($140 for the Unlimited starter plans, $50 for the phone payments, $20 for insurance and a -$20 for auto bill and paperless discount). How much can I expect my monthly payment to increase or decrease by combining all 3 lines into a family package?
