This T-Mobile 4-line promo pairs four iPhone 17s with an Essentials plan around $100 a month for 24 months, and the strongest draw is the upfront phone credit with no trade-in on many setups. Costco and Sam's Club can waive the $35 activation fee and add gift cards, while the plan includes 50GB of premium data and hotspot on paper. The main catches are taxes, fees, possible down payments, and strict port-in rules that often exclude prepaid or recent T-Mobile numbers. It is a better fit for shoppers who can meet the port and line requirements and tolerate the 24-month commitment.
Common Questions (5)
Yes. All 4 lines must be ported in to qualify, and new lines alone do not qualify. Several reports also say the port must come from an eligible carrier or MVNO, with Visible, Tello, Metro, and some other prepaid numbers sometimes rejected.
The advertised $100/month is before taxes and fees, and the real bill can land closer to about $120-$135/month depending on location. Upfront charges commonly include a $35 activation fee per line unless waived, plus sales tax on the phones and recurring regulatory fees such as the $3.99/line telco recovery fee.
The device credits are tied to keeping all 4 lines active for the full 24 months. If you shut off the 4th line, the remaining device balance for that line is still owed, and some reps warn the promo on the other lines may also be re-evaluated.
Not reliably. Keep & Switch and Family Freedom are separate pay-off programs, but multiple reports say the current no-trade-in iPhone 17 promo may not stack with them, so the account has to be checked before assuming both will apply.
The Essentials plan includes hotspot only as unlimited 3G hotspot, which is heavily throttled, and it does not include the higher-end hotspot or premium-data benefits of pricier plans. It also uses deprioritized data, so speeds can be slow in congested areas.

Keep & Switch allows you to keep your current phones, and Family Freedom requires you to trade in your old phones once T-Mobile pays them off for you. You would need to ask a T-Mobile employee whether either pay off incentive program can stack with the current no trade in required promo when you switch to T-Mobile.
